I flew back from Mexico yesterday, and had to get tested to board the flight.
Antibodies drop by as much as 90% in 6 months and as little as 20%. That leaves a range of at least 10-80% residual antibodies which is obviously MUCH greater than the global levels of March 2020. And to mattys point were talking about a booster shot here, not original distribution.I was very surprised to learn that the vaccine is only effective for roughly 6 months.
