Re: Coronavirus
A doctor said on TV yesterday that the vaccination works by exposing people to a mild dose of Covid, thus allowing their immune system to recognise the virus & prepare itself to fight it.
As a consequence, someone asked if they should have the vaccine if they've recently had the virus. The answer was yes, but to wait for four weeks before being vaccinated.
It seems odd that someone who naturally catches it doesn't become immune, but someone who is given it artificially obtains a varying level of immunity. If having and surviving Covid doesn't give one immunity, it's interesting that being given it artificially does.
