Lots of data showing vaccines wearing off. Just look at some of the studies and analysis I have linked in the past. This includes Pfizer’s own analysis of phase 3 data pre delta. VE of Pfizer is dropping 3% per month. ( linked in the past) Then other studies showing Pfizer is less effective vs delta. To get it as effective as two shots are against wild covid (the original) they need us to get a booster ( ie three shots total). This is from Pfizer’s Phase 1 booster study results. I linked it earlier.It isn't going to happen like that.
The CDC is recommending a booster for the immuno-compromised, not for the general population.
There is no data so far that the vaccines we have for the general population are "wearing off." And until that data is confirmed, which can take months and months, a booster won't be recommended by the CDC for the general population.
The U.S. has put the order in for boosters 'just in case," just like for the initial Project Warp Speed.
A new variant that is resistant to or 'hides from' the current vaccines can change all that. But... it's a case of semantics if a newly formulated vaccine for a new variant is really a "booster" or a just a "new vaccine."
The prospect of booster shots is igniting a global health debate.
Citing a lack of scientific evidence, the W.H.O. argues that extra vaccine doses should be sent to poor countries instead.www.nytimes.com
So vaccine effectiveness is going down ( Pfizer 3% per month, Moderna 1% per month pre delta), and the vaccines are less effective vs delta. So their effectiveness is decreasing over time and due to the variant ( delta). But they still have a positive effect, if diminished, and they seem more effective against serious covid ( cases requiring hospitalization) than symptomatic covid.
