The U.S. Food and Drug Administration amended the emergency use authorization (EUA) for the Pfizer-BioNTech COVID-19 Vaccine, authorizing the use of a single booster dose for administration to individuals 5 through 11 years of age at least five months after completion of a primary series with the vaccine.
On Jan. 3, the FDA authorized the use of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine for administration to individuals 12 through 15 years of age after completion of primary vaccination with the Pfizer-BioNTech COVID-19 Vaccine. Today’s action expands the use of a single booster dose of the vaccine for administration to individuals 5 through 11 years age at least five months after completion of a primary series of the Pfizer-BioNTech COVID-19 Vaccine. The FDA has authorized the Pfizer-BioNTech COVID-19 Vaccine for use in individuals 5 years of age and older and has approved Comirnaty (COVID-19 Vaccine, mRNA) for use in individuals 16 years of age and older.
“The Pfizer-BioNTech COVID-19 Vaccine is effective in helping to prevent the most severe consequences of COVID-19 in individuals 5 years of age and older,” said Peter Marks, M.D., Ph.D., director of the FDA’s Center for Biologics Evaluation and Research. “Since authorizing the vaccine for children down to 5 years of age in October 2021, emerging data suggest that vaccine effectiveness against COVID-19 wanes after the second dose of the vaccine in all authorized populations. The FDA has determined that the known and potential benefits of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine for children 5 through 11 years of age at least five months after completing a primary series outweigh its known and potential risks and that a booster dose can help provide continued protection against COVID-19 in this and older age groups.”
The EUA for a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine for children 5 through 11 years of age is based on FDA’s analysis of immune response data in a subset of children from the ongoing randomized placebo-controlled trial that supported the October 2021 authorization of the Pfizer-BioNTech COVID-19 Vaccine primary series in this age group. Antibody responses were evaluated in 67 study participants who received a booster dose 7 to 9 months after completing a two-dose primary series of the Pfizer-BioNTech COVID-19 Vaccine. The antibody level against the SARS-CoV-2 virus one month after the booster dose was increased compared to before the booster dose.
The safety of a single booster dose of the Pfizer-BioNTech COVID-19 Vaccine in this age group was assessed in approximately 400 children who received a booster dose at least five months (range 5 to 9 months) after completing a two-dose primary series. The most commonly reported side effects were pain, redness and swelling at the injection site, as well as fatigue, headache, muscle or joint pain and chills and fever.
The amendment to the EUA was granted to Pfizer Inc.
