No, I don't think so, but red measles and diptheria and whooping cough and tuberculoses are all coming back partly because of ant vaxxers refusing to have their children vaccinated. I HAD red measles in 1964 just as the first vaccines were bring released in the northeast and maybe the west coast, BUT they were NOT available in the greater New Orleans area. As a type 1 diabetic, my mother would have made it a high priority to get vaccinated. Red measles can be fatal. Antibiotic resistant TB (tuberculosis) is increasing and so is whooping cough, mumps, and possibly tetanus.
None of those are smallpox. Smallpox supposedly has been eradicated. Yes, I had ONE small pox vaccination that I remember I think I was 10 years old.
I may be wrong. Please cite your sources. Otherwise you are fear mongering and maliciously spreading misinformation.
