Shipping of the new vaccine is set to commence right away. This effort aims to ensure a strong supply and provide quick access to the vaccine at pharmacies, hospitals, and clinics nationwide.
FDA Approval and Emergency Use Authorization
Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) have announced that the U.S. Food and Drug Administration (FDA) has approved the supplemental Biologics License Application for their Omicron KP.2-adapted COVID-19 vaccine for individuals aged 12 years and older. Additionally, the FDA has granted emergency use authorization for those aged 6 months through 11 years, indicating that the vaccine is to be administered as a single dose for most individuals aged 5 years and older.
Eligibility for Further Doses
Individuals aged 5 years and older who have certain types of immunocompromise, as well as those who have previously received Pfizer and BioNTech COVID-19 vaccines, may qualify for additional doses. This also includes children under 5 who have not yet completed a three-dose series with earlier vaccine formulations.
Details on Vaccine Development
The adaptation to the KP.2 strain is backed by a substantial amount of clinical, non-clinical, and real-world evidence that supports the safety and efficacy of the vaccines developed by Pfizer and BioNTech. The supplemental application included manufacturing and non-clinical data showing that the KP.2-adapted vaccine generates a significantly enhanced immune response against the currently circulating Omicron JN.1 sublineages, including KP.2, KP.3, and LB.1, when compared to earlier vaccine formulations.
Core Technology and Approvals
Pfizer and BioNTech’s COVID-19 vaccines are based on BioNTech’s proprietary mRNA technology, which has been developed collaboratively by both companies. BioNTech holds the Marketing Authorization for COMIRNATY and its adapted variants in various global regions, including the United States, European Union, and the United Kingdom, among others.
Safety Information and Considerations
COMIRNATY (COVID-19 Vaccine, mRNA) is designed for individuals aged 12 years and older to help protect against COVID-19. While the vaccine is generally well-tolerated, there are important safety considerations to keep in mind:

- Although rare, severe allergic reactions can still occur, typically within minutes to hours after vaccination. It is advisable to monitor patients after they receive the vaccine.
- There have been reports of myocarditis and pericarditis occurring in some vaccine recipients, particularly in males aged 12 to 17, usually within days of receiving the vaccine.
- It is essential for patients seeking vaccination to inform their healthcare providers about any pre-existing medical conditions or allergies.
Side Effects and Reporting
Other side effects associated with COMIRNATY or the Pfizer-BioNTech vaccines may include mild allergic reactions, discomfort at the injection site, and general flu-like symptoms. Individuals experiencing any adverse reactions are encouraged to report them to the FDA/CDC Vaccine Adverse Event Reporting System (VAERS).
