The Food and Drug Administration has approved updated Covid-19 vaccines from Pfizer and Moderna in an effort to target recent virus strains and potential variants that may arise this winter. With millions of doses set to be shipped soon, the vaccines are designed to provide better protection against currently circulating variants.
The decision to approve the updated vaccines came earlier than last year’s rollout, as a summer wave of the virus continues to affect most parts of the country. The Centers for Disease Control and Prevention has already recommended this fall’s shot for everyone aged 6 months and older, with vaccinations expected to be available within days.
While many Americans have some level of immunity from prior infections or vaccinations, that protection tends to wane over time. Last fall’s shots targeted a different strain of the coronavirus family tree that is no longer circulating, with data showing that only a small percentage of adults and children received it.
Experts are urging eligible individuals to consider receiving the updated Covid-19 vaccine to ensure better protection against the latest variants. Robert Hopkins Jr. of the National Foundation for Infectious Diseases warns that skipping the new shot could be risky, as even a mild previous infection could lead to more severe symptoms or long Covid.
The updated vaccine recipe is tailored to target a newer branch of omicron descendants, with Pfizer and Moderna focusing on a subtype called KP.2 that was prevalent earlier this year. While additional offshoots like KP.3.1.1 are now spreading, the vaccines are expected to provide cross-protection against these variants.
The big question now is when to get vaccinated. With the current summer wave ongoing and winter surges typically being worse, high-risk individuals are advised not to wait but to schedule vaccinations as soon as they are available in their area. This includes older adults, people with weakened immune systems, nursing home residents, and pregnant individuals.
It is also crucial for more youngsters to get vaccinated this year, especially with schools reopening while Covid-19 levels remain high. Health authorities recommend getting both a Covid-19 and flu vaccination at the same time for convenience, with the prime time for flu shots typically being late September through October.
Overall, the approval of updated Covid-19 vaccines offers hope for better protection against the virus and its variants. It is important for eligible individuals to consider getting vaccinated to safeguard their health and the health of those around them.
