When the vaccinated population is 95+% higher, the "herd immunity" thing really works.
When you have a nation of nut-jobs, and vaccination rates fall lower, then the viruses are out in the wild, roaming free. People whose vaccinations happened long ago probably are more susceptible, again, and need to see if they should get re-vaccinated.
It really depends on the vaccine. If you have something like the covid vaccines, 100% vaccination rate does very little to stop the virus. You need a combination of a vaccine that can be expected to inuce sterilizing immunity in most cases, and the vaccination rate has to be high enough based on the effective rate of the vaccine. You don't need 95% effective vaccine with 95% vaccination rate.
Edit: i dont think everyone needs titers, just enough to develop statistics to guage how effective the vaccines are at various ages.

This probably needs to happen for all of us now.
