The P.1 variant is extremely contagious, with an unmitigated R somewhere in the range of 6-12. That's close to Measles. Unless a very large percentage of the population gets vaccinated, it's essentially inevitable for the unvaccinated to be infected at some point, as well as a small portion of the vaccinated population.

Your choices are either get vaccinated, get COVID (and possibly transmit it), or take extreme precautions indefinitely. Unless you have reason to believe that the vaccine is more dangerous than COVID, and you're not willing to live your life as a shut-in or wear a respirator for the rest of your life, you might as well get vaccinated.
