Wherever a virus multiplies, there’s a chance it will mutate into a variant. The more infections there are, the greater chance that will be a more dangerous variant
It may not respond to the vaccine
It may be more deadly

If there is a pool of unvaccinated people then mutations are going to continue, and may be more deadly to the young than the current ones are.
I’m sure that’s a concern for SAGE and the vaccine rollout needs to continue as far as it safely can. So must the border controls, as places like Brazil and Chile are still large breeding grounds.

But we want to go to the pub, we want to go on holiday in the sun.

Thats interesting... France has been all over the place with its vax policy. Has there been any research into mixing the different vaccines? I dont recall any other countries doing this.

Research into mix and match is underway but I haven’t seen any results as yet.

That’s an anthropological response if ever I saw one.

A virus is pretty much the dumbest “thing” that can be called living.

The good part is that virology is a pretty old and mature scientific discipline- with a plethora of peer reviewed and double/triple blind studies. The behaviour of a virus is very much open (hence predicted) to statistics- something every Western kid learns in maths.

Humans are incredibly adaptable.
Especially the ones who live through something like Covid

It would be interesting to hear of a few examples of non-novel virus which have done that.


The existing viruses have done that, the don’t kill the host, or not too many of them.
Flu goes in both directions dependent on the year, phase of the moon, zodiacal sign. Some year it transmits readily, others the incidence is low, deadliness seems to vary too.

At first glance the least 'dumb' virus ever would appear to have been in the 1980s - the HTLV3 virus, later to be known as the HIV:

After all, how clever to attack the very system protecting the host, the immune system?

Why hasn't 'disease' thought of this before?

But then it's pretty dumb to plan on killing off the very host upon which you depend to survive........
