Decades ago, we had to have vaccines against several diseases before being allowed to travel in foreign countries. Do they/we not require that today? Stupid policy if not.
Apparently it’s all mere recommendations, now.
Possibly because vaccinations had become near universal in most of the world until the the anti-vaxxer movement got legs as a result of the Wakefield fakery in the 90’s and then the internet was invented and put it on steroids.
It seems apparent that large numbers of kids are gonna have to die before people are going to get woke to the anti-vaxxer BS.
