Pfizer’s CEO says Covid vaccine effectiveness drops to 84% after six months
- Spivak 5y agoAre we not going to just do booster shots as long as reasonable? Seems silly not to at least in the short term.
- failwhaleshark 5y agoAZ should be the booster for mRNA (Pfizer and Moderna) because of its greater apparent efficacy against gamma and lambda. Also, we have to consider the interests of big pharma to sell more vaccines.
- ibeckermayer 5y agoIt's worse than that: in terms of preventing infection, vaccine effectiveness drops to 16% after about 6 months [1] (see the graph on the final page). Severe disease infection seems to last longer, but a natural hypothesis from this data is that it would fall off as well, just delayed by some unknown amount of time. Unfortunately, we probably won't find that out in any transparent way, since Israel's ministry of health [conspicuously] just announced that they'll no longer be including the relevant information in their daily data releases [2].

- nate_meurer 5y agoKeep in mind, Pfizer is pushing hard to get the government to buy third doses from them. Also keep in mind, this study of theirs hasn't been reviewed, and Pfizer is, in general, shady as fuck. Also, very important to remember, vaccines aren't intended to prevent infection, and they most don't. Vaccines are meant to prevent serious disease. So far, the sars-cov2 vaccines look good in that respect, but only time will tell.
