Then show me the many examples where he's said that vaccines are perfect proof against infection. Because now you're moving the goal posts as your point is refuted by context, so you expand to more vague ad hominem attack against him. The burden of evidence is on you to support that, and to do so with more than brief out of context soundbites.
A link to the entire transcript of an event is an "out of context sondbite"? You're clearly not discussing in good faith.
So there you are-- posting an article, maybe failing to read it or more likely deciding to ignore most of it, and then accuse me of discussing in bad faith? That is quite brazen, accusing me of the exact thing you are doing, A poor, failed attempt at a diversionary tactic to distract from your avoidance of the question.
It's not out of context, it's completely in context. Biden said you won't get COVID if you take the vaccine, full stop. There's no additional context that changes the meaning of those words.
The fact that he also made other statements about COVID doesn't render the quote out of context.
So, I don't think you and I can have a productive conversation. Perhaps you are capable of doing so when it doesn't involve a political figure, but it seems clear that you have a vendetta in this case and are unable to look past it.
If you'd like to reply for posterity, for anyone else who comes along, go for it, but don't do it on my account, I see no point in revisiting this thread. If we encounter each other in a different conversation then I look forward to the possibility of a reasonable discussion & exchange of ideas, but you don't currently, on this topic, seem interested in that.
