If you are still acting like you did last year, why bother with the

The shots are not infallible, about 95% effective for the Moderna and
Pfizer. That certainly improves your safety a great deal but we're
not totally out of the woods until some large percentage of the
population gets vaccinated. That's not going to happen until May/June
at best. Until then it pays to take reasonable precautions.
