I mostly agree. I think it is certain that vaccinations slow the spread somewhat; probable that they're stopping medical services from becoming overwhelmed; and almost certain that they will not eliminate covid from circulating. You'll probably catch covid, whether vaccinated or not. Your elderly relatives will probably catch covid, whether you and they are vaccinated or not. They'll probably catch it even if everyone on the planet become vaccinated tomorrow. Vaccination is simply one tool to moderate the effect. It's wonderful that we have them, but having 20% of the population stay unvaccinated is not going to drastically affect the spread of the disease.
