Indeed, it’s always better to be cautious about this but it won’t be good for people’s mental health if they get down every-time another variant is discovered.Would really caution against getting too wound up over variants.
Firstly, there are thousands of them.
Secondly, strong scientific consensus that very unlikely to completely bypass vaccine efficacy.
Thirdly, COVID mutates slower than flu, which we control with a new vaccine each year.
Fourthly, the vaccine technologies used make responding to new variants easier than historic technologies used.
The precautionary response against the so-called Brazil one is perfectly sensible, although in huge contrast to our reactive response in everything else!
It’s good that we are able to find and detect all the many different ones which will enable us to adjust vaccines etc when/if needed.
