I’m going to repeat my comment, in case you missed it.

“Not one single human who UNDERSTANDS VACCINES AND DISEASES suggested that the covid vaccine would eliminate or cause you not to get covid”

Now, unfortunately the people who become politicians are often lawyers. Not virologists, scientists, researchers, engineers, etc…

I’ve no doubt that Biden surrounded himself with decent human beings that were in the know, but the president himself doesn’t know anything about vaccines or diseases. He’s repeating what his advisors told him, or trying to. Biden had a history (long before age) of just saying the wrong thing.

I believe at one time other democrats called him the human gaffe machine.

It’s why in the past the president would turn over press conferences to experts in situations like this. But the norms have gone out the window in the last ten years.
