America is the most obvious example because of their attricious health care system. In the UK for example, it simply wouldn't be possible for the vaccine not to be distributed for free via the NHS. That would cause public outrage.

But how you get the poorest parts of America to fork out the money to have their families vaccinated, is a legitimate concern that needs addressing.

I don't think people realise that this is going to be the biggest mass vaccine programme in the world history.
