California has confirmed more cases of measles in people who visited Disneyland or its adjacent California Adventure park last month, health officials said on Monday, raising the number of infected people to 26.Public schools have had a devil of a time with the anti-vax crowd, since they have to allow religious or "religious" exemptions to some degree or another. But private landowners? Not so much.
It would be perfectly legal for Disney to deny entry to customers whose vaccinations aren't up to date. Maybe what will bring down anti-vaxxing won't be public health information initiatives (though that seems to be working very well in Australia), but will be commercial entities like Disney. Imagine having to show proof of vaccination before your kids are allowed into Disneyland. Score one for the invisible hand!
