Apologies if this has already been discussed but I only heard about this today. So now we have a British variant, a South African one and now a Brazilian one?
Are these new variants coming from the countries where the virus is more widespread? I don't really understand how viruses mutate, but I do find it worrying, as how will our vaccine be able to combat other variants? And will there be more of them to come? And how will it affect international travel?
Sorry, lots of questions, but does anyone have any idea about this?
