- In a Phase 2/3 clinical trial, the Pfizer-BioNTech COVID-19 Vaccine elicited a strong immune response in this age group
- Three 3-µg doses had favorable safety profile similar to placebo in young children ages 6 months through 4 years in Phase 2/3 clinical trial
- Pfizer-BioNTech COVID-19 Vaccine now authorized in the U.S. for all individuals 6 months of age and older
Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced the U.S. Food and Drug Administration (FDA) granted emergency use authorization (EUA) of the Pfizer-BioNTech COVID-19 Vaccine as a three 3-µg dose series for children 6 months through 4 years of age (also referred to as 6 months to less than 5 years of age). The 3-µg dose was carefully selected as the preferred dose for children under 5 years of age based on safety, tolerability, and immunogenicity data.
“Tens of millions of older children across the globe have already been vaccinated with our COVID-19 vaccine, helping to prevent symptomatic, severe disease and hospitalization. We know many parents in the U.S. have been eagerly awaiting an authorized vaccine for their children under 5 and we are proud to now offer them a vaccine option with a favorable safety profile,” said Albert Bourla, Chairman and Chief Executive Officer, Pfizer. “We are grateful to all the parents and caregivers who made today’s authorization possible by choosing to enroll their children in our COVID-19 vaccine clinical trial.”
“We are committed to providing access to our COVID-19 vaccine to all age groups. Parents in the U.S. now have the option to vaccinate their children under 5 years of age, and we are working to ensure that other countries worldwide will follow,” said Prof. Ugur Sahin, M.D., CEO and Co-founder of BioNTech. “The data from our Phase 2/3 study show that a dose level of 3-µg of our vaccine, which we selected based on safety, tolerability and immunogenicity data, administered in a 3-dose series, provides young children and infants with a high level of protection, also during the recent Omicron wave.”
The EUA is based on data from a Phase 2/3 randomized, controlled trial that included 4,526 children 6 months through 4 years of age. In the trial, children received the third 3-µg dose at least two months after the second dose at a time when Omicron was the predominant variant. Following a third dose in this age group, the vaccine was found to elicit a strong immune response, with a favorable safety profile similar to placebo.
The clinical trial results were reviewed by the FDA Vaccines and Related Biological Products Advisory Committee (VRBPAC) on June 15, who unanimously recommended authorization. The U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) will meet June 17 and June 18 to discuss a potential recommendation for the use and rollout of the vaccine to children 6 months through 4 years of age. Vaccinations for children 6 months through 4 years of age are anticipated to start subject to and after the CDC endorses the ACIP recommendation.
Pfizer and BioNTech will begin shipping 3-µg pediatric doses as directed by the U.S. government. Eligible U.S. residents will continue to receive the vaccine for free, consistent with the U.S. government’s commitment to free access to COVID-19 vaccines.
The companies plan to submit requests for authorization of their COVID-19 vaccine in this age group to other regulators around the world, including the European Medicines Agency in early July.
About the Phase 1/2/3 Trial in Children
The Phase 1/2/3 trial has enrolled more than 10,000 children ages 6 months to under 12 years of age in the United States, Finland, Poland, Spain and Brazil from more than 90 clinical trial sites. The trial evaluated the safety, tolerability, and immunogenicity of the Pfizer-BioNTech COVID-19 Vaccine in three age groups: ages 5 to under 12 years; ages 2 to under 5 years; and ages 6 months to under 2 years. Based on the Phase 1 dose-escalation portion of the trial, children ages 5 to under 12 years received a two-dose schedule of 10 µg each while children under age 5 received three lower 3-µg doses in the Phase 2/3 study. The trial enrolled children with or without prior evidence of SARS-CoV-2 infection.
