Vaccinations has to a degree the same issue as masks. The question isn't if they work, but rather how effective they are in different contexts. It seems we are now at three vaccinations for just 2021, and multiple different mutations of the virus. I hope strongly this third dose will be it and this latest mutation will be the final one, however listening to researchers that discuss the subject makes me less hopeful.

The exit criteria is that the general population get enough protection that covid outcomes behave similar to other seasonal flu viruses. The hope is that this will be achieved through a combination of vaccinations and time, but we won't know until the data is in. What is known in many countries is that transmission of covid by vaccinated people has surpassed greatly those of unvaccinated (by simple quantity of people who are vaccinated), which is why masks in high risk areas is still recommended for tipple vaccinated people. I would recommend a mask in NYC subway to combat Covid regardless of how much vaccine you have taken.
