Clinical trial results for the original monovalent Pfizer-BioNTech COVID-19 Vaccine (administered as a two-dose primary series) demonstrated that among vaccine recipients age 12–15 years, side effects during the 7 days after vaccination were commonly reported (90.9% of vaccine recipients reported a local reaction and 90.7% reported a systemic reaction). Most reactions were mild to moderate. Pain at the injection site was the most common local reaction. One in 10 reported a side effect that interfered with daily activities. Side effects usually resolved after 1–2 days. Systemic side effects (e.g., fever, fatigue, headache, muscle pain) were more commonly reported after the second dose than after the first dose. No specific safety concerns were identified among adolescent vaccine recipients.
The safety and side effects of the 2023–2024 formula mRNA vaccine introduced in September 2023 are expected to be consistent with the previous formulations of the product.

Yes. The 2023–2024 formula Novavax vaccine is an option for any person age 12 years or older who is unvaccinated or was previously vaccinated with any COVID-19 vaccine and is due for a 2023–2024 updated vaccination. The dose may be given at least 2 months after the most recent dose of a previous COVID-19 vaccine formulation. Any person age 12 years or older who has never had a dose of COVID-19 vaccine should receive two doses of Novavax vaccine, administered 3 to 8 weeks apart as a primary series. People with moderate to severe immunocompromise may receive a third dose at least 2 months following the second dose, and may receive subsequent additional doses at the discretion of their healthcare provider, in consideration of their individual circumstances.
