> Many people who are double vaccinated are testing positive for COVID and therefore capable of spreading it
Yes, but the fact that symptoms tend to be much weaker in the vaccinated likely means it's less likely to spread from them. Currently, the problem is that we have those breakthrough cases, plus also the unvaccinated still spreading the disease.
That said, it's true that the new delta variant may mean we need further boosters.
As mentioned in the parent comment I made, it's a game of odds. It's one thing wearing a mask at the supermarket and passing someone with covid. But if I go to the office, pick up COVID, and I live in the same home as someone who is immunocompromised, they don't stand a chance. This is the reality for many millions of families around the world.
