> “So even though there are breakthrough infections with vaccinated people, almost always the people are asymptomatic and the level of virus is so low it makes it extremely unlikely — not impossible but very, very low likelihood — that they’re going to transmit it,” Fauci said.

So, almost noone vaccinated will get it, and those who do, won't spread it.

So, people literally died, because they though they coudln't get it, and went out, and other people who though they couldn't spread it, spread it around.
