Ummm....I am guessing that Liza is NOT calling for vaccines to be issued coercely to those who don't need them or who aren't directly prescribed to them by their doctors.
But...why not? If a healthy person wanted additional protection against all kinds of predatory viruses, why shouldn't he/she get such protection?
But yeah, she's dead on. Get the profit motive and price gouging out of medicine, and give us universal healthcare.
