Rand Paul and mandatory vaccination

Rand Paul, whatever his other flaws and virtues, is a physician, so his comments on vaccination on Monday caused considerable eyebrow-raising, and accusations, muted or not, of either pandering to the tinfoil brigade or of his not being a very good physician.

Will Wilkinson at The Economist parses Dr Paul’s comments, and gives a cogent (IMO) “liberaltarian” defence of (virtually) mandatory vaccination.
