Good thinking. This new spike protein is supposedly hard for your body to break down, but only poisonous in very large quantities. Personally, I'm not taking any precautions, but the people I know who got the shot are avoiding me, so same result. The media has done a good job describing those who haven't gotten the shot as dangerous. The many women saying their periods got fucky after hanging out with vaccinated people is concerning, but it's impossible to rule out things such as intercourse, which would make way more sense than breathing in spike proteins floating in the air. These spike proteins collect in the testes, brain and lungs (again, supposedly) in men.
