It seems like you got it in your head that the COVID vaccines would be a able to stop infection entirely, and were disappointed when it didn't for your family. It's not surprising that you did: a lot of the messaging at the time really counted their chickens before they hatched and painted it as a miracle prophylactic. In the real world, vaccines are a population-level tool with a range of outcomes. It's annoyingly hard to communicate that to the masses. In practice, it turns out that fighting fast-mutating viral respiratory infections is hard to do. Our immune just aren't that great at it, and vaccines can only stack the deck there so much in our favor. I believe that the (observational, hard to rely on) evidence suggests that the covid vaccine reduced the incidence of infection, but only by about 25-50%. And that's good! That doesn't even cover the much more substantial reduction in serious outcomes! A world with the vaccines is unarguably less hostile than that without. But it's not a miracle, and it's always aggravating when people engage in the nirvana fallacy about it.
