Geez! How did we all survive before they created these vax protocols! When I was a kid the only vax we got were the forced smallpox shot and the sugar cube polio vax given to us at school without parent permission in the 1960’s. My baby sister who was 3 years old and did not receive the smallpox jab developed a form of smallpox that almost killed her. This was in Riverside, California. I use to be able to google the outbreak, but they have pretty much removed any reference to this occurring.
I was curious about the smallpox outbreak that affected your sister in the 60’s. Somehow I thought everybody had to be vaccinated for it then but maybe you got vaccinated before going to kindergarten. You’re lucky you didn’t get it!!
I went to Grok and it had no information. It said it would look further if it had more details, e.g. exact year. You’ll probably have more success. I did find this article.
