Don't forget, the best Covid vaccines are 95% effective. That leave 5% who do still get symptoms of reinfection. Most vaccines do NOT prevent reinfection. They just make your immune system well prepared in case you do get infected. I suspect people get reinfected all the time, but have no symptoms because their immune system wipes out the virus quickly. If you are vaccinated, it behooves you to make sure you are never exposed to such a high viral load you get symptoms. We can do that by following all the sensible public health guidelines we have known for the last year.

We're flying electric helicopters on Mars yet you can't turn on your clothes dryer in Texas. That's because scientists are in charge of Mars, and Republicans are in charge of Texas.
