On May 9, 2024, the Food and Drug Management (FDA) authorized updated COVID-19 vaccines from Moderna, Novavax, and Pfizer-BioNTech designed to target current circulating variants. These vaccines are intended for use in individuals 12 years and older,marking a shift towards an annual vaccination schedule similar to the flu vaccine.
The FDA’s authorization followed a meeting of its Vaccines and Related Biological Products Advisory Committee (VRBPAC) on May 8, 2024, where the committee unanimously recommended updating the COVID-19 vaccines. According to the FDA’s press release, the updated vaccines will target the KP.2 variant,a descendant of Omicron,which is currently a dominant strain in the United States.
The authorized vaccines include:
- Moderna: Spikevax 2024-2025
- Novavax: Updated COVID-19 Vaccine,2024-2025
- Pfizer-BioNTech: 2024-2025 COVID-19 Vaccine
These vaccines are mRNA vaccines (Moderna and Pfizer-BioNTech) and a protein subunit vaccine (Novavax). They are designed to elicit an immune response against the spike protein of the virus, which is crucial for preventing severe illness, hospitalization, and death.
Why Update the Vaccines?
The COVID-19 virus continues to evolve, with new variants emerging regularly. Previous vaccines, while effective, have shown reduced efficacy against newer variants. the FDA’s decision to update the vaccines reflects the need to adapt the vaccination strategy to maintain protection against circulating strains. As explained by CIDRAP, the goal is to provide a vaccine that closely matches the currently dominant strains, maximizing the immune response.
The VRBPAC’s recommendation was based on data demonstrating that the updated vaccines elicit a strong immune response against current variants. The committee also considered the potential for future variant emergence and the need for a flexible vaccine platform that can be quickly adapted to address new threats.
What Does This Mean for You?
The updated vaccines are expected to be available in the fall of 2024, coinciding with the typical start of the respiratory virus season.The Centers for Disease Control and Prevention (CDC) will provide recommendations on who should receive the updated vaccine and when. NBC News reports that the CDC’s Advisory Committee on Immunization Practices (ACIP) will meet in June 2024 to discuss these recommendations.
Experts anticipate that the updated vaccines will be recommended for individuals at high risk of severe illness, including older adults, people with underlying medical conditions, and immunocompromised individuals. However, the CDC may also recommend vaccination for a broader population, similar to the annual flu vaccine.
The FDA emphasized that the updated vaccines are safe and effective. The agency continues to monitor the safety of COVID-19 vaccines through various surveillance systems.
