I think that it is safe to say that the ideal for almost everyone is eradication. I think that even people who are opposed to vaccines could agree. I do not know many people who have had a smallpox vaccine.
Perhaps I am missing the finer points of forum etiquette. But when someone starts a thread about vaccines and I make a post about a vaccine, I do not expect to be told that I am too far off topic and should start a new thread.
