To the editor: Since herd immunity doesn't require a 100% vaccination rate, a good compromise for California is to let the unvaccinated enroll in schools with greater than a 95% vaccination rate (if enrolling the kid won't push the rate below the threshold). The unvaccinated would have less school choice and may have to move, but they would not be forced into home-schooling. ("Much in common, but worlds apart on the issue of vaccinating children," June 5)
Forcing a medical treatment — even a safe one — is a big intrusion. It is justified to save a kid from major risk or to prevent him from endangering others; other than that, give parents their autonomy.
