Germany, Italy, France to halt AstraZeneca shots, further hitting EU vaccination campaign

By Thomas Escritt and Stephanie Nebehay

BERLIN/GENEVA (Reuters) – Germany, France and Italy said on Monday they would stop administering the AstraZeneca COVID-19 vaccine after several countries reported possible serious side-effects, throwing Europe’s already struggling vaccination campaign into disarray.

Denmark and Norway stopped giving the shot last week after reporting isolated cases of bleeding, blood clots and a low platelet count. Iceland and Bulgaria followed suit and Ireland and the Netherlands announced suspensions on Sunday.

The moves by some of Europe’s largest and most populous countries will deepen concerns about the slow rollout of vaccines in the region, which has been plagued by shortages due to problems producing vaccines, including AstraZeneca’s.

Germany warned last week it was facing a third wave of infections, Italy is intensifying lockdowns and hospitals in the Paris region are close to being overloaded.

German Health Minister Jens Spahn said that although the risk of blood clots was low, it could not be ruled out.

“This is a professional decision, not a political one,” Spahn said adding he was following a recommendation of the Paul Ehrlich Institute, Germany’s vaccine regulator.

France said it was suspending the vaccine’s use pending an assessment by the EU medicine regulator due on Tuesday. Italy said its halt was a “precautionary and temporary measure” pending the regulator’s ruling.

Austria and Spain have stopped using particular batches and prosecutors in the northern Italian region of Piedmont earlier seized 393,600 doses following the death of a man hours after he was vaccinated. It was the second region to do so after Sicily, where two people had died shortly after having their shots.

The World Health Organization appealed to countries not to suspend vaccinations against a disease that has caused more than 2.7 million deaths worldwide.

“As of today, there is no evidence that the incidents are caused by the vaccine and it is important that vaccination campaigns continue so that we can save lives and stem severe disease from the virus,” WHO spokesman Christian Lindmeier said.

The United Kingdom said it had no concerns, while Poland said it thought the benefits outweighed any risks.

“UNUSUAL” SYMPTOMS

AstraZeneca’s shot was among the first and cheapest to be developed and launched at volume since the coronavirus was first identified in central China at the end of 2019 and is set to be the mainstay of vaccination programs in much of the developing world.

Thailand announced plans on Monday to go ahead with the Anglo-Swedish firm’s shot after suspending its use on Friday but Indonesia said it would wait for the WHO to report.

The WHO said its advisory panel was reviewing reports related to the shot and would release its findings as soon as possible. But it said it was unlikely to change its recommendations, issued last month, for widespread use, including in countries where the South African variant of the virus may reduce its efficacy.

The European Medicines Agency (EMA) has also said there was no indication the events were caused by the vaccination and that the number of reported blood clots was no higher than seen in the general population.

The handful of reported side-effects in Europe have upset vaccination programs already under pressure over slow rollouts and vaccine skepticism in some countries.

The Netherlands said on Monday it had seen 10 cases of possible noteworthy adverse side-effects from the AstraZeneca vaccine, hours after the government put its vaccination program on hold following reports of potential side-effects in other countries.

Denmark reported “highly unusual” symptoms in a 60-year-old citizen who died from a blood clot after receiving the vaccine, the same phrase used on Saturday by Norway about three people under the age of 50 it said were being treated in hospital.

“It was an unusual course of illness around the death that made the Danish Medicines Agency react,” the agency said in a statement late on Sunday.

One of the three health workers hospitalized in Norway after receiving the AstraZeneca shot had died, health authorities said on Monday, but there was no evidence that the vaccine was the cause. They said they would continue their probe and that no more suspected cases had been reported since Saturday.

AstraZeneca said earlier it had conducted a review covering more than 17 million people vaccinated in the European Union and the UK which had shown no evidence of an increased risk of blood clots.

Investigations into potential side-effects are complicated as the history of each case and circumstances surrounding a death or illness are examined. Austrian authorities have said their review of the AstraZeneca batch will take about two weeks.

The EMA has said that as of March 10, a total of 30 cases of blood clotting had been reported among close to 5 million people vaccinated with the AstraZeneca shot in the European Economic Area, which links 30 European countries.

The WHO said that as of March 12, more than 300 million doses of COVID-19 vaccines had been administered around the world with no deaths found to have been caused by any of them.

Kenya hails first vaccine ‘bazookas,’ Rwanda secures Pfizer shots

By Omar Mohammed and Clement Uwiringiyimana

NAIROBI/KIGALI (Reuters) – Kenya received over a million doses of the AstraZeneca COVID-19 vaccine on Wednesday, while Rwanda said it was the first in Africa to secure shots from Pfizer, as efforts to inoculate the world’s poorest nations accelerated.

With fewer resources and tougher logistics than other regions, African nations are racing to secure the doses needed to protect their roughly 1.3 billion people and allow the safe reopening of economies.

Africa has been relatively lightly hit by the coronavirus compared with other regions, recording 104,000 deaths, according to a Reuters tally. That is lower than national tolls in the United States, India, Brazil, Russia and Britain.

Kenya’s batch, which arrived on a Qatar Airways passenger flight, is the first of an initial allocation of 3.56 million doses by the global COVAX facility.

“We have received … machine guns, bazookas, and tanks to fight this war against COVID-19,” Health Minister Mutahi Kagwe exulted as the doses arrived at Nairobi’s main airport.

COVAX, which is led by the GAVI vaccines alliance along with the World Health Organization (WHO) and other partners, aims to deliver over 1.3 billion doses to 92 lower- and middle-income countries, covering up to 20% of their populations.

Backers of the initiative hope to level a playing field that has seen wealthier nations quickly vaccinate millions, ahead of poorer regions. Only a few African nations have started inoculating citizens with vaccines acquired outside of COVAX.

First shots under COVAX are arriving at several African nations this week, including Nigeria, Senegal and Uganda.

Senegal, which received 200,000 doses developed by China’s Sinopharm last month, got an additional 324,000 shots of the AstraZeneca vaccine on Wednesday, via COVAX.

COLD STORAGE

In Kigali, officials said Rwanda will get the first doses of the Pfizer COVID-19 shots to be dispatched to Africa under the vaccine-sharing scheme. The Pfizer vaccine presents an extra logistical challenge because it requires ultra-cold storage.

The batch of 102,960 doses were due in Kigali on Wednesday, hours after a flight landed carrying 240,000 AstraZeneca doses from the Serum Institute of India, the health ministry said. The government has installed special infrastructure to keep the vaccine at -70 degrees.

“Rwanda is one of the first countries among the low income countries to have ultra-cold chain,” said Fode Ndiaye, the United Nations’ resident coordinator.

Rwanda plans to start its vaccination drive on Friday, prioritizing frontline health workers and others at high risk. It hopes to vaccinate 30% of its roughly 12 million people before the end of this year.

Despite Africa’s comparatively low fatalities, fragile economies across the continent are reeling from lockdowns.

Kenya, which has so far recorded 106,470 infections and 1,863 deaths, has taken a major economic hit from the virus, which cut the flow of tourists, a crucial source of foreign exchange and jobs.

Nairobi plans to prioritize 400,000 health workers nationwide in a vaccination campaign starting on Friday, the health ministry said.

It will join Ivory Coast, Ghana and South Africa among the nations in sub-Saharan Africa to start vaccination drives.

COVAX vaccine program to deliver 237 million doses to 142 nations by end-May

GENEVA/LONDON (Reuters) – The COVAX vaccine-sharing program said on Tuesday it will deliver 237 million doses of AstraZeneca’s COVID-19 shot to 142 countries by the end of May as it steps up the global roll-out of its vaccine supplies.

The timeline for the delivery of doses, made by AstraZeneca and by India’s Serum Institute, will be split into separate two-month schedules, COVAX said in a statement, with the first in February-March and the second in April-May.

“These timelines are dependent on a variety of factors including national regulatory requirements, availability of supply, and fulfillment of other criteria such as validated national deployment and vaccination plans,” the statement said.

COVAX is the World Health Organization-backed program to provide vaccines for poor and middle-income countries. It began its roll-out last week with the first deliveries of shots to Ghana and Ivory Coast.

Hailing the campaign as an “unprecedented partnership,” WHO Director-General Tedros Adhanom Ghebreyesus said Angola, Cambodia, Democratic Republic of Congo and Nigeria could also expect deliveries of COVAX-supplied vaccines on Tuesday.

“This is an unprecedented partnership that will not only change the course of the pandemic but also change the way the world responds to future health emergencies,” Tedros told a joint media briefing with the U.N. Children’s Fund UNICEF, the GAVI vaccines alliance – which co-leads COVAX – and others.

Ghanaian President Nana Akufo-Addo told the same briefing that his West African country, which this week began its inoculation campaign with COVAX doses, aimed to vaccinate 20 million people by the end of 2021.

COVAX added in a statement that as well as the first round of allocations of the AstraZeneca vaccine, some 1.2 million doses of the Pfizer-BioNTech COVID shot were also anticipated for delivery in the first quarter of 2021.

EU warns it could block vaccine exports, wields legal threat at drugmakers

By John Chalmers and Philip Blenkinsop

BRUSSELS (Reuters) – Europe’s fight to secure COVID-19 vaccine supplies intensified on Thursday when the European Union warned drug companies such as AstraZeneca that it would use all legal means or even block exports unless they agreed to deliver shots as promised.

The EU, whose member states are far behind Israel, the United Kingdom and the United States in rolling out vaccines, is scrambling to get supplies just as the West’s biggest drugmakers slow deliveries to the bloc due to production problems.

As vaccination centers in Germany, France and Spain cancelled or delayed appointments, the EU publicly rebuked Anglo-Swedish drugmaker AstraZeneca for failing to deliver and even asked if it could divert supplies from Britain.

European Council President Charles Michel said in a letter to four EU leaders that the EU should explore legal means to ensure supplies of COVID-19 vaccines it contracted to buy if negotiations with companies over delayed deliveries are unsuccessful.

“If no satisfactory solution can be found, I believe we should explore all options and make use of all legal means and enforcement measures at our disposal under the Treaties,” Michel said in the Jan. 27 letter.

EU rules on monitoring and authorizing exports of COVID-19 vaccines in the 27-nation bloc could lead to exports being blocked if they violated existing contracts between the vaccine maker and the EU, an EU official said.

The European Commission is to lay out the criteria under which such exports would be evaluated on Friday.

VACCINE CRUNCH

The swiftest mass vaccination drive in history is stoking tensions across the world as big powers buy up doses in bulk and poorer nations try to navigate a financial and diplomatic minefield to collect whatever supplies are left.

Israel is by far the world leader on vaccine rollout per head of population, followed by the United Arab Emirates, the United Kingdom, Bahrain and the United States. Behind them are Italy, Germany, France, China and Russia.

The African Union (AU) has secured another 400 million doses of the AstraZeneca COVID-19 vaccine, a regional health leader said on Thursday, in a push to immunize 60% of the continent’s population over three years.

Under fire from the EU, AstraZeneca CEO Pascal Soriot said the EU was late to strike a supply contract so the company did not have enough time to iron out production problems at a vaccine factory run by a partner in Belgium.

Tensions have risen as both New York-based Pfizer and AstraZeneca, headquartered in Cambridge, England, have had production problems.

Britain, which has repeatedly touted its lead in the vaccine rollout race since leaving the EU’s orbit on Jan. 1, said its deliveries must be honored.

“I think we need to make sure that the vaccine supply that has been bought and paid for, procured for those in the UK, is delivered,” Minister for the Cabinet Office Michael Gove told LBC Radio.

Just a day ahead of a decision by European regulators on whether to approve the drugmaker’s shot, Germany’s vaccine committee said AstraZeneca’s vaccine should only be given to people aged between 18 and 64.

“There are currently insufficient data available to assess the vaccine efficacy from 65 years of age,” the committee, also known as Stiko, said in a draft resolution made available by the health ministry on Thursday.

Britain’s Johnson said health authorities in Britain believed the vaccine was safe and worked across all age groups.

APPOINTMENTS CANCELLED

In the northern French region of Hauts-de-France, France’s second-most-densely-populated region, several vaccination centers were no longer taking appointments for a first jab. In several other French regions, some online appointment platforms closed booking options.

Spain’s Madrid region has ceased first vaccinations for at least this week and next and was using the few doses it has to administer second shots to those who have had the first one, said deputy regional government chief Ignacio Aguado.

Germany’s most populous state, North Rhine-Westphalia, last week postponed opening its vaccination centers until Feb. 8, while the state of Brandenburg has also had to push back vaccination appointments originally scheduled for the end of January due to delivery delays.

AstraZeneca is prepared to publish the delivery contract it has with the European Union and aims on Friday to make proposals to the European Commission on which sensitive parts to black out, the Frankfurter Allgemeine reported.

The newspaper quoted an EU source as saying that while AstraZeneca would not be able to deliver the 80 million doses expected for the first quarter, volumes should significantly exceed the 31 million doses that had earlier been reported.

Africa secures 400 million more COVID-19 vaccine doses

By George Obulutsa

NAIROBI (Reuters) – The African Union (AU) has secured another 400 million doses of the AstraZeneca COVID-19 vaccine, a regional health leader said on Thursday, in a push to immunize 60% of the continent’s population over three years.

As richer nations race ahead with mass immunization campaigns, Africa is scrambling to obtain supplies for its 1.3 billion people. Only a handful of African nations have begun giving doses.

John Nkengasong, director of the AU’s disease control and prevention body, told an online briefing that in addition to 270 million doses previously secured, the bloc would get 400 million shots from the Serum Institute of India (SII) – all AstraZeneca/Oxford University shots.

A spokesman for the SII declined comment.

The AstraZeneca vaccine is the cheapest option and one of the best-suited to African health systems as it does not require storage at ultra-low temperatures like the vaccine from Pfizer and German partner BioNTech.

Separately from the AU’s efforts, Africa is to receive about 600 million vaccine doses this year via the COVAX facility co-led by the World Health Organization (WHO).

Health authorities hope to vaccinate about 30-35% of Africans this year, rising to 60% in two to three years. The AU has said vaccines secured by its vaccine task team will be allocated according to population.

Though COVID-19 has not hit Africa as badly as some experts had feared it would, wealth disparities, logistical difficulties and “vaccine nationalism” by developed nations may put the world’s poorest continent at a disadvantage.

Africa has reported 3.5 million infections and 88,000 deaths, according to a Reuters tally. That is fewer fatalities than individual nations the United States, Brazil, India, Mexico and Britain.

OUTLIER TANZANIA

In an implicit rebuke to Tanzanian President John Magufuli, who has discouraged mask-wearing and social distancing, discontinued data publication and called vaccines a malign foreign plot, WHO Africa director Matshidiso Moeti urged Tanzania to implement such measures, prepare vaccinations and share data. “Africa is at a crossroads and all Africans must double down on preventive measures,” she told an online news conference on Thursday, saying WHO officials were in touch with Tanzanian officials. “Science shows that vaccines work.”

Magufuli’s government has published no coronavirus data since May 8, when the country had 509 cases and 21 deaths.

On Wednesday, he said, without evidence, that vaccines were a foreign plot to spread illness and steal Africa’s wealth. He urged Tanzanians instead to trust God and use alternative remedies such as steam inhalation.

“We in Tanzania managed to stay for a year without corona. Even here, no one has put on a mask. Our God is beyond Satan and Satan will always fail using different diseases,” he said in a speech in his western home area.

Nkengasong said the Africa CDC was exploring obtaining more vaccines from China, Russia and Cuba, and would work with any partner whose vaccine was safe and effective.

Madrid halting COVID-19 vaccinations due to supply delays

MADRID (Reuters) – Delays to COVID-19 vaccine shipments have forced authorities in Madrid to halt inoculations and are threatening supplies in Catalonia, Spanish officials said on Wednesday.

The Madrid region has ceased first vaccinations for at least this week and next and was using the few doses it has to administer second shots to those who have had the first one, said deputy regional government chief Ignacio Aguado.

“We need more doses and we need them now,” he told reporters on Wednesday, urging newly appointed Health Minister Carolina Darias to act quickly to secure the shots.

U.S. pharmaceutical giant Pfizer said last week there would be a temporary slow down in shipments to the European Union in late January caused by changes to manufacturing processes to ultimately boost output.

The announcement angered some EU governments and the executive European Commission due to the slow pace of vaccine roll outs in the 27-nation bloc.

It is also in dispute with Anglo-Swedish pharmaceutical firm AstraZeneca, which developed its shot with Oxford University and notified the EU on Friday that it could not meet supply targets for the first quarter of the year.

Spain’s 14-day incidence of the virus hit a record 900 cases per 100,000 people on Wednesday and the Health Ministry reported 40,285 new infections and 492 deaths.

Officials in Madrid and Catalonia said at the current pace it would be impossible to reach the national target of 70% of Spain’s 47 million population vaccinated by July.

Catalan health secretary Josep Maria Argimon said the region would use up all its stockpile of vaccines in the coming days and will have to administer second shots later than planned due to supply delays, citing an undelivered shipment of the Moderna vaccine scheduled for this week as one example.

The affluent northeastern region will issue a new request for 30,000 vaccine doses that it expects to administer starting on Feb. 4, Argimon told a news briefing.

Spain has administered just over 1.3 million doses to a priority group of care-home residents and frontline medics, around 77% of its current stocks.

UK AstraZeneca vaccine plant partially evacuated over suspect package

LONDON (Reuters) – A factory in Wales that produces AstraZeneca’s COVID-19 vaccine was partially evacuated on Wednesday after it received a suspicious package and police said a bomb disposal unit was dealing with the incident.

Operated by Wockhardt UK, the plant provides so-called fill-and-finish capacity for AstraZeneca’s UK supply chain, which is the final manufacturing step of putting vaccines into vials or syringes and packaging them.

AstraZeneca has agreed to supply Britain with 100 million doses of the vaccine, developed by Oxford University.

It is currently engaged in a dispute with the European Union after it cut supplies to the bloc due to production issues at its Belgian factory.

“Wockhardt UK in Wrexham this morning received a suspicious package to site. All relevant authorities were immediately notified and engaged,” the company said, referring to its facility outside the town of Wrexham in north Wales.

“Upon expert advice we have partially evacuated the site pending a full investigation. The safety of our employees and business continuity remain of paramount importance,” it said.

Local police confirmed that a bomb disposal unit was on site and advised the public to avoid the area.

“We are currently dealing with an ongoing incident on the Wrexham Industrial Estate,” they said in a statement.

AstraZeneca vaccine can be up to 90% effective; COVID-19 reinfection unlikely for at least six months

By Nancy Lapid

(Reuters) – The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.

AstraZeneca COVID-19 vaccine shows up to 90% efficacy

An interim analysis of late-stage trials of AstraZeneca’s COVID-19 vaccine finds it prevented 70% of COVID-19 cases with no confirmed serious adverse effects, the company announced on Monday. In 8,895 participants who got two full doses, the efficacy was 62%. But due to a dosing error that proved to be a happy accident, among 2,741 volunteers who got a half dose followed by a full dose, efficacy rose to 90%. Pfizer and Moderna reported that their vaccines were about 95% effective at preventing illness. But AstraZeneca’s vaccine is cheaper, easier to make, and can be stored at normal refrigerator temperatures. Investment analysts at SVB Leerink said Astra’s vaccine was unlikely to gain U.S. approval because safety data so far are inadequate and the trial design did not meet U.S. requirements for representation of high-risk groups such as the elderly and minorities. AstraZeneca said it plans to seek approval to modify its U.S. study to get more data on the smaller initial dose. Eventually, all three vaccines could prove comparable. “My suspicion is that by the time we are a year down the line, we’ll be using all three vaccines with about 90% protection,” said immunologist Danny Altmann of Imperial College London.

COVID-19 reinfection appears unlikely for at least 6 months

People who have had COVID-19 are unlikely to contract it again for at least six months, British researchers said on Thursday in a report posted on medRxiv ahead of peer review. Between April and November, they tracked more than 12,000 frontline healthcare workers at high risk for infection with the new coronavirus. COVID-19 with symptoms occurred in 89 of 11,052 workers who did not already have antibodies showing exposure to the virus, whereas none of the 1,246 staff with antibodies developed a recurrent infection. Staff with antibodies were also less likely to test positive for COVID-19 without symptoms, the researchers said. “This is really good news because we can be confident that, at least in the short term, most people who get COVID-19 won’t get it again,” said coauthor David Eyre of Oxford’s Nuffield Department of Population Health. Maria van Kerkhove of the World Health Organization added, “We still need to follow these individuals for a longer period of time to see how long immunity lasts.”

Delirium may signal COVID-19 in elderly

Delirium is common among older patients with COVID-19 and may be their only symptom, U.S. researchers warned on Thursday in JAMA Network Open. Among more than 800 COVID-19 patients over age 65 who showed up at emergency departments around the country, nearly 30% had delirium, they found. Overall, delirium was the sixth most common of all the symptoms and signs in these older patients. Those most at risk for delirium included elders with vision or hearing impairment, stroke, Parkinson’s disease and residents of assisted living or skilled nursing facilities. Delirium is not on any official list of COVID-19 signs and symptoms, but the U.S. Centers for Disease Control and Prevention (CDC) should add it, said coauthor Dr. Maura Kennedy of Massachusetts General Hospital in Boston. “Sometimes delirium is the chief complaint when these patients arrive at the emergency department,” Kennedy said. “But there can be a number of reasons they come, including falls that occurred because of the delirium. They may present without what we consider typical COVID-19 symptoms, such as fever, shortness of breath and cough.”

New data help distinguish COVID-19 from flu

Certain findings can help distinguish COVID-19 from influenza or other respiratory illnesses, a new study suggests. Israeli doctors studied 693 hospitalized patients with COVID-19, plus more than 8,000 adults who had been hospitalized in previous years for the flu or severe respiratory infections. Compared to the other patients, those with COVID-19 were on average younger, more overweight, and had fewer preexisting conditions other than dementia, which was more prevalent in COVID-19 patients. Upon hospital admission, COVID-19 patients had overall lower levels of infection-fighting white blood cells and neutrophils, but their hearts were beating faster, they had less oxygen in their blood, and they had higher percentages of immune-system B cells, which produce antibodies to attack invading germs, and T cells, which destroy cells that have become infected. During the first two days of hospitalization, white blood cell and neutrophil levels rose in COVID-19 patients but fell in the other groups, the researchers said in a paper posted on Sunday on medRxiv ahead of peer review. “At the dawn of winter, recognizing the characteristics discriminating COVID-19 from influenza, will be critical to support the management of the current pandemic,” they conclude.

AstraZeneca COVID-19 vaccine shows promise in elderly, trial results by Christmas

By Kate Kelland and Alistair Smout

LONDON (Reuters) – AstraZeneca and Oxford University’s potential COVID-19 vaccine produced a strong immune response in older adults, data published on Thursday showed, with researchers expecting to release late-stage trial results by Christmas.

The data, reported in part last month but published in full in The Lancet medical journal on Thursday, suggest that those aged over 70, who are at higher risk of serious illness and death from COVID-19, could build robust immunity.

“The robust antibody and T-cell responses seen in older people in our study are encouraging,” said Maheshi Ramasamy, a consultant and co-lead investigator at the Oxford Vaccine Group.

“We hope that this means our vaccine will help to protect some of the most vulnerable people in society, but further research will be needed before we can be sure.”

Late-stage, or Phase III, trials are ongoing to confirm the findings, researchers said, and to test whether the vaccine protects against infection with SARS-CoV-2 in a broad range of people, including people with underlying health conditions.

Results of those trials should definitely be known by Christmas, the Oxford Vaccine Group’s director, Andrew Pollard, said, adding it was too early to know whether and how well the vaccine works in preventing COVID-19 disease.

“We’re still waiting to get to the point where we can do the analysis to just work out how well the vaccine can protect people, and we’re getting ever closer to that,” he told journalists.

“We are optimistic that we’ll be able to do that before Christmas, and obviously we’ll share that with you as soon as we can at that point.”

The Oxford-AstraZeneca COVID-19 vaccine candidate, called AZD1222 or ChAdOx1 nCoV-19, had been among the front-runners in global efforts to develop shots to protect against infection with the novel coronavirus, or SARS-CoV-2.

But rival drugmakers Pfizer Inc, BioNTech and Moderna Inc have in the past 10 days edged ahead, releasing data from late-stage COVID-19 vaccine trials that shows more than 90% efficacy.

“We’re not in a rush. We and it’s not a competition with the other developers,” Oxford’s Pollard said, adding that AstraZeneca would release headline efficacy data before it was published in an academic journal.

Oxford University has set a target of 53 infections to start the interim analysis of its late-stage trial results, though “lots of cases” in its trial arms in Britain, South Africa and Brazil mean the exact number of infections reported could differ.

Unlike the Pfizer-BioNTech and Moderna shots, both of which use new technology known as messenger RNA (mRNA), AstraZeneca’s is a viral vector vaccine made from a weakened version of a common cold virus found in chimpanzees.

The Phase II trial reported in The Lancet involved a total of 560 healthy volunteers, with 160 aged 18-55, 160 aged 56-69, and 240 aged 70 or over.

Volunteers got two doses of the vaccine or a placebo, and no serious side effects related to the AZD1222 vaccine were reported, the researchers said.

AstraZeneca has signed several supply and manufacturing deals with companies and governments around the world.

India sees early vaccine launch as AstraZeneca deliveries run late

By Krishna N. Das

NEW DELHI (Reuters) – India raced ahead with work on its coronavirus vaccine while Britain’s AstraZeneca said its deliveries were running “a little bit late” as countries around the world sought to conquer the pandemic and rescue their economies.

A vaccine is seen as the world’s best bet for taming a virus that has infected more than 48 million people, led to more than 1.2 million deaths, roiled economies and disrupted billions of lives since it was first identified in China in December.

Australia is beefing up its prospective arsenal against the pandemic to 135 million doses of various vaccine candidates.

“We aren’t putting all our eggs in one basket,” Prime Minister Scott Morrison said on Thursday.

Some 45 vaccine candidates are in human trials worldwide, with Pfizer Inc saying it could file in late November for U.S. authorization, opening up the possibility of a vaccine being available in the United States by the end of the year.

Moderna and AstraZeneca are close behind the largest U.S. drugmaker and are likely to have early data on their vaccine candidates before the end of the year.

An Indian government-backed vaccine could be launched as early as February – months earlier than expected – as last-stage trials begin this month and studies have so far showed it is safe and effective, a senior government scientist told Reuters.

Bharat Biotech, a private company that is developing COVAXIN with the government-run Indian Council of Medical Research (ICMR), had earlier hoped to launch it only in the second quarter of next year.

“The vaccine has shown good efficacy,” senior ICMR scientist Rajni Kant, who is also a member of its COVID-19 task force, said at the research body’s New Delhi headquarters.

“It is expected that by the beginning of next year, February or March, something would be available.”

Bharat Biotech could not immediately be contacted.

A launch in February would make COVAXIN the first India-made vaccine to be rolled out.

VACCINE KEPT FROZEN

AstraZeneca has signed multiple deals to supply more than three billion doses of its candidate to countries around the world.

But a summer dip in British coronavirus infections had pushed back test results, leading the drugmaker to delay deliveries of shots to the government.

Britain’s vaccines chief said on Wednesday it would receive just 4 million doses of the potential vaccine this year, against initial estimates for 30 million by Sept. 30.

AstraZeneca said on Thursday it was holding back deliveries while it awaits the data from late-stage clinical trials in order to maximize the shelf-life of supplies.

“We are a little bit late in deliveries, which is why the vaccine has been kept in frozen form,” CEO Pascal Soriot said on a conference call.

AstraZeneca and its partner on the project, the University of Oxford, said that data from late-stage trials should land this year.

The United States leads the world in both the number of COVID deaths and infections and the pandemic was a polarizing issue in Tuesday’s presidential election in which votes were still being counted.

Australia’s Morrison said the government would buy 40 million vaccine doses from Novavax and 10 million from Pfizer and BioNTech.

That adds to the 85 million doses Australia has already committed to buy from AstraZeneca and CSL Ltd should trials prove successful.

Among other vaccine candidates around the world, a growing number of Russians are unwilling to be inoculated once a vaccine becomes widely available, the Levada Centre, Russia’s only major independent pollster, said this week.

Russia, raising eyebrows in the West, is rolling out its “Sputnik V” vaccine for domestic use despite the fact that late-stage trials have not yet finished.
