From my memory, in the early sixties, even though vaccination had already been OK'd, my father wrote to Org to get permission to get us vaccinated against smallpox before we went to a JW free location where the 'need was great'.
The need wasn't great at all, but he got the OK from the bOrg and the place he went to got infected with JW doctrine. Many of the people that he convinced would be preserved through Armageddon and make it into Paradise with all of the wonderful benefits that would come with being the 'other Sheep' are already dead. So is he.
