I think that the official line as of 10:13 mountain time on 8/8/21 is that if you take the vaccine you can still get sick, you just don't get AS sick as someone that's unvaccinated.
I about lost it when Biden tried to recount the urban legend about people going on a ventilator and then begging for the vaccine and the poor overworked doctors having to say "It's too late". Give me a f**king break huh? Who's that stupid? Take the vaccine or don't, I don't care, just don't expect me to mask up to protect your ass.
