The U.S. Food and Drug Administration (FDA) yesterday proposed updating the COVID-19 boosters every fall, like the flu shot.
The proposal: FDA says the move will simplify vaccine administration and “potentially increase vaccine compliance” by allowing a consistent, easy-to-follow message about getting vaccinated.
How it would work: As they do with flu shots, the FDA would assess SARS-CoV-2 strains annually, and each summer would recommend the strain to be targeted by the fall booster. If a dangerous “vaccine-escape variant” emerges, FDA could address it at any time.
What about the original formulas? The annually updated formulas would replace the original COVID vaccines. Young children who have not received a vaccine yet, and older or high-risk individuals, would be recommended two shots of the newest, targeted formula.
Why they’re proposing it: The FDA notes that “real-world evidence” from a variety of sources shows the updated bivalent boosters are effective. Even the highly contagious and immunity-evasive XBB.1.5 variant has been kept in check by the vaccines, which appear to protect against hospitalization and death.
The next steps: The FDA’s Vaccines and Related Biological Products Advisory Committee meets Thursday to vote on the recommendation.
The big picture: Fears of a “tripledemic” of COVID-19, influenza, and Respiratory Syncytial Virus (RSV) are abating, thanks to the COVID-19 vaccines and a drop-off in RSV cases, says The Washington Post: “The immune systems of those who have been vaccinated or previously infected are still effective at keeping the cases mild, especially if they have recently received booster shots.”
