Infection rates aren't what the vaccines were looked at to bring down though. It's hospitalizations and deaths. I think that's a big problem with how many people look at their vaccinations. Yes, vaccination reduces risk of spread but it's not really a case of hey I'm, safe to be around because I'm vaccinated. It's more of a case of hey, it's ok I go to a busy place where covid may be circulating as I'm unlikely to need to take up a hospital bed if I get COVID. This is a big part of why we allow vaccinated people to gather when unvaccinated people cannot.
