Vaccination when? My immunity was gone when I got tested at 35 so I had to re-take the shots. I was telling everyone I knew to get titers done for themselves.
Usually, you don’t need a booster once you got fully vaccinated (2 shots, usually combined with mumps and rubella vaccines). However, the second shot was not the recommended practice until around the 90s, so you might have received only one and then it’s a good idea to get it checked.
We don’t actually know that. We don’t have studies of lifelong effectiveness of the extra shot. Does it extend protection? Yes. By how much? We’ve been doing it for 30+ years, so we don’t know

If everyone, or at least most (Over 90%.) had had the first shot, how necessary would the second shot have been?
Still necessary; they started doing the second shot because they found that immunity was dropping off fairly quickly with only one dose
