evidence: Assoumou: The vaccines are safe, and remarkably effective. But what precautions to take will decide on a lot of factors. For example, where you live. Are you in a place with high vaccination coverage, like Massachusetts, or a southern state with low vaccination coverage and high case rate. It also depends on what activity you are engaging in. Outside not in a crowd, that’s safe. You don’t need a mask, but inside in a crowd where you don’t know who is vaccinated or unvaccinated, then you may still want to follow public health measures. If you have children less than 12, like I do, then you also need to be a little more cautious. In addition, if you have a compromised immune system, then you also need to take some precautions. If you happen to be in a place with high vaccination coverage and a lower case rate, then it might depend on your level of comfort for risk.
