I'm a little suspicious of this Pfizer Covid-19 vaccine, largely because I was always going to be suspicious of whichever vaccine made a claim to have come "first" in a perceived race. I've seen enough games launch prematurely in an attempt to get the jump on competitors that I'm not impressed by glory-seeking.

I'd like to know more about how it works, though. The way I understand it, the vaccine turns your own cells into machines that produce pieces of the virus which the immune system can latch onto and destroy. This means that should the virus itself appear, the defences are in place to see it off.

That sounds swell, but I don't know for how long the cells produce pieces of the virus. Do they do it just once? If so, that's fine. Do they do it maybe a couple of dozen times? That's going to be OK too. Do they do it indefinitely? That sounds as if it could cause problems in the long term. Do they do it until the cells themselves are destroyed by the immune system? That doesn't sound good at all. Maybe the second dose of the vaccine turns it off.

I think I'll have to wait for an explanation to appear using language accessible to non-viroligists.
