My Dad was a public health inspector way back when all these diseases killed and maimed. I remember getting each and every vaccine as it became available as he was so involved in public health. He was very, very, pro vaccine in an age when people were very sceptical of new things.
We have lost that knowledge now. We are so conditioned to modern healthcare that we believe most things can be cured. even when caught. COVID should have taught us that is not always the case. Unfortunately it has gone the other way, even though millions died of it, people no longer trust vaccines.
Both my Mum and her partner died of COVID pre-vaccine. Started with mild colds, dead within two weeks, on the same day. Brutal.
