RE: Brazil Variant16 Jan 2021 11:34
The problem is not so much the Brazil variant, it is what has happened there, and what this tells us about coronavirus. Last spring the city of Manaus was particularly hard hit by covid with around two thirds of the population infected. Less than a year later, the city has been struck by a new outbreak of covid and seemingly a more infectious variant than the first outbreak, with mutations which mean it is sufficiently different from the first strain that the virus is able to reinfect them. So much for herd immunity, and it may well be that a new vaccine is needed every year as with flu. I have a feeling we may be fighting coronavirus for a while yet.
