It can happen! When a vaccine is 97% effective, that means for 3% of people who get it as directed, they still won’t have full immunity. A lot of the time it can be fixed with extra shots, since for some people (or even just with some vaccines) their bodies need a little extra ‘training’ before it works.
To corroborate with personal experience, I got a third round in 2019 for grad school, but post-vaccine blood test showed only a moderate increase in resistance to measles.
Doc said immunity to measles in particular can be resistant to training for many individuals and recommended postponing another booster unless traveling to a country where measles was a problem. Guessing he didn’t imagine that country might be the USA.
Since I live in a city with a lot of tourism from states with burgeoning measles epidemics, I’m getting my fourth booster in April. Oy vey.
