“Correlation does not imply causality”. But Gupta did admit that autism, at least in male children, is on the rise, and it isn’t entirely clear that it is simply more reporting of it and enlarged definitions.
But Michael Gerson, in the Washington Post Feb. 3, p A15, "Threatened by free riders: Those who skip vaccination endanger everyone" (or online "The public good versus individual freedom") argues that herd immunity works only when about 90% of the population is immune, so that the immunocrompromised person on chemotherapy (who can't "choose" vaccination) isn't endangered. The state should take compulsory measures necessary to bring the rate up to 90%. That is, those who don't have a medical reason to avoid vaccination are riding on the willingness of everyone else to take a very small risk for the public good (link). As noted, though, this kind of reasoning affects other areas, like the old military draft.
