Even as the Omicron wave winds down, federal health officials, experts, and the vaccine makers are already preparing for a potential fourth COVID shot to protect against whatever may come next, Axios' Caitlin Owens writes. The catch: It's not yet clear whether another booster shot will be needed. And if it is, there are even more questions around who should receive one and what kind of shot would be most effective. What they're saying: "The potential future requirement for an additional boost or a fourth shot for mRNA or a third shot for J&J is being very carefully monitored in real-time. And recommendations, if needed, will be updated according to the data as it evolves," NIAID director Anthony Fauci told reporters last week. State of play: Fourth doses are already authorized for immunocompromised people. However, for most people, data suggest that a single booster shot offers strong protection against severe disease, including from Omicron. - But the big question is how long that protection against hospitalization and death will last.
- The U.K. recently decided that it will soon offer fourth shots to the elderly and some people with health conditions, per The Sunday Times.
Zoom in: Israel has already offered fourth shots and has begun to release preliminary data on their effect. The bottom line: The need for another booster shot will also depend on how much the virus keeps circulating. Go deeper. |
