broad power when it comes to vaccinations. i think more broad power than people may recognize. the states clearly can mandate vaccinations. i don't mean just say you have to be vaccinated to go into restaurants but can mandate needles in arms. the supreme court said that. to a point of the doctor, states do and can require vaccinations for public school children. now, there are some fair questions about whether the mayor holds the power a state legislature holds. the general principle is that wh when you have a reasonable medical need. i think this is more than reasonable. there's an awful lot the government can do, and i think you're right. modelling is an important phenomenon here. we've seen it on the private sector where we've seen more and bigger private corporations start to require vaccinations and their employees and others follow suit. >> doctor, this is just going to be a requirement to have one dose in order to have access to the indoor facilities.
