Some vaccines are more effective than others.  Polio is known to be an
effective one, as is Tetnus.  I have not seen stats on measles or mumps,
but I also didn't know anyone who got mumps growing up because we all had
to get the shot (not sure about measles).

The COVID vaccines seemed to depend on which brand you got.  J&J was not at
all effective, where Moderna had better stats and Pfizer was somewhere in
between.  Like the flu vax, you have to keep up with boosters to keep up with
the mutations.  If you don't get the boosters, you cannot really blame the vax
when you come down with a new strain that was not known of when the original
vax (or maybe even last booster) came out.
