I remember ‘scientists’, last year, consistently saying that this virus is stable. Unusually stable, in fact. It doesn’t mutate. It’s so unusual how stable it is. Other coronaviruses, like the flu, mutate a lot. But not this one.
This was the consensus. The message was consistent and unchanging. Just like the virus. Until one day, when the vaccines started being rolled out, suddenly, it isn’t so stable anymore.
Interesting to say the least.
