A lot of people get flu shots every year, but I don't hear a lot of complaining about it. Why? Because the virus mutates. All. The. Time. Same with COVID. As a child I got a DPT booster shot every few years, polio boosters frequently, etc., etc. Instead of looking at reinfection rats, maybe you should look a the mortallity statistics. Last time I checked, the unvaccinated were dying at a rate of 13 times more than the vaccinated. . . And the vaccine is supposed to decrease the severity of COVID infections and keep you from, you know, dying.
