Re: measles, this isn’t necessarily the case. Breakthrough infections have been known and discussed before.[0] The measles vaccine efficacy is estimated at 97% implying 3% chance of a breakthrough.
However, Covid-19 vaccine efficacy against infection was originally 93-95% but has dropped to 60% or less against the Delta variant. A lot of discussion seems to ignore this. To get back to the 90% plus efficacy we’ll need the vaccine to be re-tuned against delta, which no one seems in a rush to do for some reason…
