(Reuters) – The U.S. Food and Drug Administration is preparing to authorize Pfizer Inc and German partner BioNTech SE’s COVID-19 vaccine for adolescents aged between 12 and 15 years by early next week, the New York Times reported on Monday, citing federal officials familiar with the agency’s plans.

An approval is highly anticipated after the drugmakers said in March that the vaccine was found to be safe, effective and produced robust antibody responses in 12- to 15-year-olds in a clinical trial.

Responding to a Reuters request for comment, the FDA said its review of expanding the vaccine’s emergency use authorization is ongoing, but did not provide further details.

The vaccine has already been cleared in the United States for people aged 16 and above.

Pfizer declined to comment on the NYT report.

The U.S. Centers for Disease Control (CDC) Director Rochelle Walensky said earlier in April that the vaccine could be approved by mid-May.

If an approval for the 12-15 year old’s is granted, the CDC’s vaccine advisory panel will likely meet the following day to review the clinical trial data and make recommendations for the vaccine’s use in adolescents, the report added.

A potential approval of the vaccine would boost the country’s immunization drive and help allay fears of parents anxious to protect their children from COVID-19.

Moderna Inc and Johnson & Johnson are also testing their vaccines in 12- to 18-year old’s, with data from Moderna’s trial expected to come soon.

Pfizer and Moderna have also launched trials in even younger children, aged six months to 11 years old. Both companies have said they hope to be able to vaccinate children under 11 as soon as early 2022.
