According to another site our immunity has laspsed. Ten years is the max. Also the formula was changed in the early to mid fifties because they used the monkey pox. They discovered is had a carcenigen in it thats why most 90% of the population that was vaccinated 1955 and back have cancer!
Oh horse hooey ! I don't have cancer , and I doubt that EVERYONE who was vacinated prior to '55 , has cancer either. If you are correct,why aren't we all dead or dying?
I was originally vacinated prior to '55.I was also given at least one ( and I think two ) booster shots;one in '61 and the other in '67 !
