"If they try locking us down again what's the point in bothering to get jabbed?"
They'll say lockdown was becessary because not enough people were jabbed..
Don't forget the figures they quote every evening are for vaccinations of
adults - kids carry it too. I suspect we'll have to get teenagers done.
"It's excellent news the jabs seem to be effective at currently all known strands.."
It's tentatively looking that way. Significantly effective anyway, especially if a modified vaccine is produced. Moderna did one, and AZ's is on the books. It looks like we can fight known possible variations of the spike with what we have and what we could easily make.
The virus is, simplified, a spike, plus "the rest", in a string of 30,000 nucleotides, like ACUAGACUGAAA etc etc making say
/\_._._._._._._._._._._._._._
The spike is the bit which it "Gets in" with, so that's the bit which all the vaccines target. If the virus changes its spike, the vaccines may not fit as well, but if the spike changes
a lot, then it won't do what's necessary for the virus anyway.
"The rest" is lots of bits like antigen defeaters, duplication enablers, virus "capsule" makers and quite a lot we don't understand very well, so we don't really know how it does us damage in all the various organs, affecting the brain; for long covid; etc.
It's quite a big virus so it has a repairing mechanism(!) to correct errors when it replicates, but there are still mutations going on in "the rest".
The vaccines ONLY work against the spike bit, because that's the easy bit to recognize the virus with, as a bad thing.
(The MERS virus had a different sort of spike which went for a different receptor (not ACE2) and the vaccines were well on the way for MERS. That's why it was relatively quick to change the recipe for SARs-CoV-2 (covid) ).
If one of the mutations in "the rest" made it become really bad, given that the vaccines aren't perfect and don't stop everything getting in , we could still get a nasty variant.
Wot I mean is - say we have 25% getting infected despite vaccines now, but only with no/mild symptoms. No real drama, arguably. If something in that non-spike bit changed so it killed 33% though, (MERS was) it would be killing around 1 in 12. That's a proper flapping situation.
Vaccines aganst bits of "the rest" would be a different kettle of potatoes altogether, because they aren't accessible on the envelope(capsule) of the virus like the spike is.
It's all jolly interesting
