Science is only as good as it’s scientists.
Here’s one for you, you may or may not know.
Were you at school when the dreaded BCG injection was out?
Do you recall that is you got the 6 little dots swelling you didn’t have to have the BCG because you were “immune” to TB or you “had your own resistance”
Did you know that’s shown to be a load of bollocks.
It actually meant that you had latent TB which could become active at any time given the right conditions. Nowadays if you get the swelling of the dots they offer you a course of treatment to get rid of it.
Science and scientist eh!
