I actually have my smallpox vaccination. I received an experimental dilution in 2002 to test whether or not the existing supply could be diluted to protective levels in order to save the country.
My sister has had the anthrax vaccine, and she's fine today.
Neither one is issued to people on a regular basis due to the severe (for vaccines) side effects that outweigh the risks of not vaccinating. Smallpox because it is effectively eradicated, anthrax because there is a low risk of natural (non bio-weapons) exposure.
Thats not what these people are b*tching about - they're complaining about vaccines where the risk of NOT vaccinating is very high (pertussis, measles, chicken pox, etc...) and the risks from vaccination are very low.
