Pfizer and BioNTech Announce US FDA Approval of their COVID-19 Vaccine COMIRNATY For Adolescents 12 through 15 Years of Age – Pfizer

NEW YORK and MAINZ, GERMANY, July 8, 2022 Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced the U.S. Food and Drug Administration (FDA) approved the companies supplemental Biologics License Application (sBLA) for their COVID-19 vaccine, known as COMIRNATY (COVID-19 Vaccine, mRNA), to include individuals 12 through 15 years of age. The vaccine was previously made available to this age group in the U.S. under emergency use authorization (EUA), and to date more than 9 million 12- to 15-year-old adolescents in the U.S. have completed a primary series.i

Todays approval is based on data from a Phase 3 clinical trial of 2,260 participants 12 through 15 years of age. A two-dose primary series of the vaccine (30-g dose) elicited SARS-CoV-2neutralizing antibody geometric mean titers (GMTs) of 1,239.5, demonstrating strong immunogenicity in a subset of adolescents one month after the second dose. This compared well (was non-inferior) to GMTs elicited by participants aged 16 to 25 years old (705.1 GMTs) in an earlier analysis. In the trial, a two-dose primary series of the vaccine (30-g dose) was also 100% effective (95% confidence interval [CI, 87.5, 100.0]) in preventing COVID-19, measured between a week and more than four months after the second dose. During this time, all 30 cases of confirmed symptomatic COVID-19 were in the placebo group (n=1,109) and no cases were in the COMIRNATY group (n=1,119). The only SARS-CoV-2 variant of concern identified from the confirmed COVID-19 cases in this age group was Alpha as the efficacy analysis was conducted between November 2020 and May 2021, which was before the Delta and Omicron surges. No cases of severe disease occurred in either the COMIRNATY or placebo group. The adverse event profile was generally consistent with other clinical data for the vaccine, with a favorable safety profile observed across 6 months of safety follow-up data after the second dose.

Pfizer and BioNTech also filed these data with the European Medicines Agency (EMA) and other regulatory authorities around the world.

COMIRNATY is now the only COVID-19 vaccine approved by the FDA as a two-dose primary series for individuals 12 years and older. An EUA for a primary series in U.S. adolescents ages 12 through 15 years was previously granted in May 2021 based on initial data from the same pivotal Phase 3 clinical trial. Longer-term follow-up data, announced in November 2021, confirmed the safety and effectiveness of COMIRNATY in adolescents 12-15 years of age and were required for licensure. In the European Union the conditional marketing authorization in this age group was granted by EMA in August 2021.

COMIRNATY was previously FDA approved for individuals 16 years and older in August 2021. Pfizer and BioNTech have also submitted a sBLA to the U.S. FDA to extend the approval of COMIRNATY to include booster doses for individuals ages 16 years and older, who are currently authorized under EUA.

COMIRNATY, which is based on BioNTechs proprietary mRNA technology, was developed by both BioNTech and Pfizer. BioNTech is the Marketing Authorization Holder in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Pfizer and BioNTech also are pursuing regulatory approvals for this age group in other countries where emergency use authorizations or equivalents have been granted.

IMPORTANT SAFETY INFORMATION

Tell your vaccination provider about all of your medical conditions, including if you:

Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY (COVID-19 Vaccine, mRNA) may not protect all vaccine recipients

You should not receive COMIRNATY (COVID-19 Vaccine, mRNA) or Pfizer-BioNTech COVID-19 Vaccine if you have had a severe allergic reaction to any of its ingredients or had a severe allergic reaction to a previous dose of COMIRNATY or Pfizer-BioNTech COVID-19 Vaccine.

There is a remote chance that COMIRNATY (COVID-19 Vaccine, mRNA) or the Pfizer-BioNTech COVID-19 Vaccine could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose of the vaccine. For this reason, your vaccination provider may ask you to stay at the place where you received the vaccine for monitoring after vaccination. If the vaccine recipient experience a severe allergic reaction, call 9-1-1 or go to the nearest hospital

Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received the vaccine, particularly 7 days following the second dose. The observed risk is higher among males under 40 years of age than among females and older males. The observed risk is highest in males 12 through 17 years of age.

Seek medical attention right away if you have any of the following symptoms after receiving the vaccine:

Fainting can happen after getting injectable vaccines, including Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY (COVID-19 Vaccine, mRNA). Sometimes people who faint can fall and hurt themselves. For this reason, your vaccination provider may ask the vaccine recipient to sit or lie down for 15 minutes after receiving the vaccine

Some people with weakened immune systems may have reduced immune responses to Pfizer-BioNTech COVID-19 Vaccine or COMIRNATY (COVID-19 Vaccine, mRNA)

In people 12 through 15 years of age, the most common side effects (8%) were pain at the injection site, fatigue, headache, chills, muscle pain, fever, joint pain, injection site swelling, and injection site redness.

In people 16 through 55 years of age, the most common side effects (10%) were pain at the injection site, fatigue, headache, muscle pain, chills, joint pain, fever, and injection site swelling.

In people 56 years of age and older, the most common side effects (10%) were pain at the injection site, fatigue, headache, muscle pain, chills, joint pain, injection site swelling, fever, and injection site redness.

These may not be all the possible side effects of the vaccine. Call the vaccination provider or healthcare provider about bothersome side effects or side effects that do not go away.
