Pfizer and BioNTech Submit a Variation to EMA for the Vaccination of Children Ages 6 Months to less than 5 Years with COMIRNATY®

NEW YORK and MAINZ, Germany, July 8, 2022Pfizer Inc. (NYSE: PFE, “Pfizer”) and BioNTech SE (Nasdaq: BNTX, “BioNTech”) today announced that the companies have submitted a variation to the European Medicines Agency (EMA) requesting to update the Conditional Marketing Authorization (CMA) in the European Union (EU) with data supporting the vaccination of children 6 months to less than 5 years of age (also referred to as 6 months through 4 years of age) with the 3-µg dose of COMIRNATY® (COVID-19 vaccine, mRNA) as a three dose series. 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. 

The submission included data from a Phase 2/3 randomized, controlled trial that included 4,526 children 6 months to less than 5 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. No new safety signals were identified, and the frequency of adverse reactions observed in children 6 months to less than 5 years were generally lower than in children 5 to less than 12 years of age.

Pfizer and BioNTech submitted the same data to the U.S. Food and Drug Administration (FDA) which granted emergency use authorization (EUA) of the Pfizer-BioNTech COVID-19 vaccine as a three 3-µg dose primary series in this age group in June 2022 The companies also plan to submit these data to other regulatory agencies around the world.

COMIRNATY, which is based on BioNTech’s 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 the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries. Submissions to pursue regulatory approvals in those countries where emergency use authorizations or equivalent were initially granted are planned.

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.

AUTHORIZED USE IN THE EU:
COMIRNATY® ▼ (the Pfizer-BioNTech COVID-19 vaccine) has been granted conditional marketing authorization (CMA) by the European Commission to prevent coronavirus disease 2019 (COVID-19) in people aged 5 years and older. The vaccine is administered as a 2-dose series, 3 weeks apart. Adults and adolescents from the age of 12 are given 30 micrograms per dose; children aged 5 to 11 years are given 10 micrograms per dose. In addition, the CMA has been expanded to include a booster dose (third dose) at least 3 months after the second dose in individuals 12 years of age and older. A third primary course dose may be administered at least 28 days after the second dose to people aged 5 years and older with a severely weakened immune system. The European Medicines Agency’s (EMA’s) human medicines committee (CHMP) has completed its rigorous evaluation of COMIRNATY®, concluding by consensus that sufficiently robust data on the quality, safety and efficacy of the vaccine are now available.

IMPORTANT SAFETY INFORMATION:

  • Events of anaphylaxis have been reported. Appropriate medical treatment and supervision should always be readily available in case of an anaphylactic reaction following the administration of the vaccine.
  • Very rare cases of myocarditis and pericarditis have been observed following vaccination with Comirnaty. These cases have primarily occurred within 14 days following vaccination, more often after the second vaccination, and more often in younger males. Available data suggest that the course of myocarditis and pericarditis following vaccination is not different from myocarditis or pericarditis in general. The risk of myocarditis after a third dose of COMIRNATY has not yet been characterized.
  • Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress‐related reactions (e. g. dizziness, palpitations, increases in heart rate, alterations in blood pressure, tingling sensations and sweating) may occur in association with the vaccination process itself. Stress-related reactions are temporary and resolve on their own. Individuals should be advised to bring symptoms to the attention of the vaccination provider for evaluation. It is important that precautions are in place to avoid injury from fainting.
  • The efficacy, safety and immunogenicity of the vaccine has not been assessed in immunocompromised individuals, including those receiving immunosuppressant therapy. The efficacy of COMIRNATY may be lower in immunosuppressed individuals.
  • As with any vaccine, vaccination with COMIRNATY may not protect all vaccine recipients. Individuals may not be fully protected until 7 days after their second dose of vaccine.
  • In clinical studies, adverse reactions in participants 16 years of age and older were injection site pain (> 80%), fatigue (> 60%), headache (> 50%), myalgia and chills (> 30%), arthralgia (> 20%), pyrexia and injection site swelling (> 10%) and were usually mild or moderate in intensity and resolved within a few days after vaccination. A slightly lower frequency of reactogenicity events was associated with greater age.
  • The overall safety profile of COMIRNATY in adolescents 12 to 15 years of age was similar to that seen in participants 16 years of age and older. The most frequent adverse reactions in clinical trial participants 12 to 15 years of age were injection site pain (> 90%), fatigue and headache (> 70%), myalgia and chills (> 40%), arthralgia and pyrexia (> 20%).
  • There is limited experience with use of COMIRNATY in pregnant women. Administration of COMIRNATY in pregnancy should only be considered when the potential benefits outweigh any potential risks for the mother and fetus.
  • It is unknown whether COMIRNATY is excreted in human milk.
  • Interactions with other medicinal products or concomitant administration of COMIRNATY® with other vaccines has not been studied.
  • For complete information on the safety of COMIRNATY always make reference to the approved Summary of Product Characteristics and Package Leaflet available in all the languages of the European Union on the EMA website.
