My favorite part is where the referenced document doesn't say that. It literally shows that a third shot of Pfizer-Biontech is still 90+% effective against the Delta variant after 10+ weeks. And close to 50% against Omicron after 10+ weeks. The only significance of 10 weeks is that was where their data ended, because boosters haven't been generally available that long.
- collias 5y agoI'd definitely consider 50% efficacy against the most prevalent variant (by far) after 10 weeks to be "waning". That might change if we ever get a booster targeted toward Omicron specifically, but we don't have one, and by the time we do, I'm sure there will be other variants around.
