The rest is my personal choice to not take a booster.

It looks like it possibly starts waning at 2 months. So if we're requiring everyone needs to be fully vaccinated with mandates then boosters start at 2 months to be safe. By that measure large portions of our population are not fully vaccinated at this point. No thanks...
