I’m really not sure if it’s a good thing that we’re finding out about these new strains. Most of them haven’t been any worse than the ones we have already but everyone panics about them. Perhaps a case of too much information being a bad thing? For the general public anyway.
But most of them are worse than the ones we already have, either because they are much more transmissible or because vaccines have lower efficacy against them (or both). Of course we should know about them, imagine what people would be saying if this information was deliberately hidden from the public and what that would do to public trust and confidence as well as fuelling the conspiracy theorists.
In any case the information would be impossible to hide as it comes from the scientists not the government and as we don't live in an authoritarian state, scientists are free to publish their findings.
Personally I am glad to live in a democracy, where you are treated like an adult and given relevant information and people in the UK should be proud of the fact that the UK is a world leader in genomic sequencing and surveillance - this is something which will save lives not just here, but globally as it means new variants are picked up sooner and action can be taken sooner (tweaking vaccines for example).
