I know nothing is free (tax will be extracted to cover the cost eventually) but the fact that we benefit from a free health system is shown so clearly in this situation. No one needs to be scared of not being able to pay for or not having access to it. If I lived in some countries I would not have access or would have to find the cost. As much as everything could always be better we represent a lucky society.
Developing those vaccines and bringing them to market, then delivering them is quite a spectacular thing to have watched happen even if it feels like it has taken quite some time from our individual dug-outs.
Once we, the lucky privileged, are done then the next step is to help suppress it around the rest of the world.
