Always ask, If the vaccine was so effective we wouldn’t be up to 4 boosters by now. They even admitted that it isn’t as effective especially against variants. Soon they will probably stop admitting it and just tell you to keep taking vaccines without any explanation but that’s besides the point.
On the other hand if the natural antibodies weren’t enough to protect individuals, you would have seen a rise in cases to the likes of the beginning of the pandemic. You have not seen that so obviously the previously infected population have not gotten reinfected. What other evidence for you need?
Makes you question why are they pushing the vaccines so aggressively on the whole population with no scientific basis aside for what they conveniently make up as they go along…
