We’ve all been waiting for this upgrade. Shots should be available as soon as next week:
Today, the U.S. Food and Drug Administration approved and granted emergency use authorization (EUA) for updated mRNA COVID-19 vaccines (2024-2025 formula) to include a monovalent (single) component that corresponds to the Omicron variant KP.2 strain of SARS-CoV-2. The mRNA COVID-19 vaccines have been updated with this formula to more closely target currently circulating variants and provide better protection against serious consequences of COVID-19, including hospitalization and death. Today’s actions relate to updated mRNA COVID-19 vaccines manufactured by ModernaTX Inc. and Pfizer Inc.
In early June, the FDA advised manufacturers of licensed and authorized COVID-19 vaccines that the COVID-19 vaccines (2024-2025 formula) should be monovalent JN.1 vaccines. Based on the further evolution of SARS-CoV-2 and a rise in cases of COVID-19, the agency subsequently determined and advised manufacturers that the preferred JN.1-lineage for the COVID-19 vaccines (2024-2025 formula) is the KP.2 strain, if feasible.…
Per the Washington Post, “New coronavirus vaccines are now approved. Here’s what to know” [gift link]:
The Food and Drug Administration approved new mRNA coronavirus vaccines Thursday, clearing the way for shots manufactured by Pfizer-BioNTech and Moderna to start hitting pharmacy shelves and doctor’s offices within a week…
The FDA has yet to approve an updated vaccine from Novavax, which uses a more conventional vaccine development method but has faced financial challenges.
Our scientific understanding of coronavirus vaccines has evolved since they debuted in late 2020. Here’s what to know about the new vaccines:
Why are there new vaccines?
The coronavirus keeps evolving to overcome our immune defenses, and the shield offered by vaccines weakens over time. That’s why federal health officials want people to get an annual updated coronavirus vaccine designed to target the latest variants. They approve them for release in late summer or early fall to coincide with flu shots that Americans are already used to getting…
Who needs a new coronavirus vaccine?
The United States differs from other countries in recommending an updated coronavirus vaccine for everyone except young infants, rather than just those at heightened risk for severe disease because they are 65 or older, are moderately to severely immunocompromised or have serious medical conditions…
How long does vaccine protection last?
CDC data shows that the effectiveness of the 2023-2024 vaccine, meant to reduce emergency room visits and hospitalizations, declined sharply more than four months after receiving it. But the risk of hospitalization still remains low for most people, which made it harder for the CDC to compare outcomes for people who received an updated shot with those who did not…
