After having the BCG (TB) jab back in the 1960's, my schoolmate Jimmy was off school for a week with a fever and an infection at the site of the jab., which shows even in those days there was risk associated with jabs.
(nearly every schoolkid in Britain inculding me had the jab, we didn't really want it but were bullied into it by our parents, teachers and the media who were all saying it was a "good thing")
Before that in the 1950's we all had the polio jab too, again because we were told it was a "good thing", but as far as i know nobody had an adverse reaction.
PS- around that time lots of pregnant women had the Thalidomide jab which caused many babies to be born badly deformed.
Huh, so much for trusting "medical science".
