To be fair, we don't vaccinate against smallpox anymore because the risks of the vaccine outweigh the benefits. It's not prima facie irrational to believe that the risks of other vaccines outweigh the benefits. I've never heard of anyone being persuaded by being insulted, so perhaps we should instead approach the anti-vaxxers with hard data showing how yes, their concerns are in fact grounded in fact, but there are also other facts that make vaccination the right decision in most, but not all, cases.
