The vaccines we have received were based on the original Covid-19 strain
out of China. The dominant strain around the world is the Delta variant,
so the most likely mutations that a person will encounter in the near
term will derive from that.

Since a full vaccinated person seems to be well protected against
serious illness from the Delta variant, exposure to it will provide the
immune system with a heads up about something closer to a future mutation.

Just a thought.

Hi, Sylvia,

Why is this important?

Are they going to draw blood from infected-but-vaccinated people to transfuse into others who have the Indian version of COVID to help with recovery?

I suspect that an exposure to a small number of deltas, without a
raging infection, won't affect one's immune system.

Having a semi-serious delta bout might be a sort of vaccine.

I wonder how protective a delta infection is against the original
strain.

The mass vaccination hubs have long queues, so seems most are trying
to do the right thing, there is a percentage point of persons having
been vaccinated where this virus will burn out, become extinct.

That hasn't happened to influenza.

With a concerted effort to vaccinate the entire world against covid-19,
we might achieve extinction. Otherwise, we'll constantly be dealing with
new variants. The vaccine producers probably quite like that idea - they
can make booster shots for ever more. Governments should take a
different view, but I see little evidence of it.

Like the influenza virus?

The effectiveness of a vaccine can be expected to decrease as the virus
mutates away from the strain used for the vaccine. My thought was that
exposure to a more recent variant allows one to play catchup at little risk.

Not necessarily, the most important mutations
aren't always of the most commonly seen variant.

That utterly mangles the story all over again.

Just another of your steaming turds, actually.

That's much less likely with the delta, it has
a lot higher viral load than the original strain.

But when the viral load is much higher, it will.

That's true of all the strains.

No evidence that it isn't. Its only the brazil
strain that has seen much reinfection of
already infected people so far.

And there isn't a lot of the original strain
around now, so its rather academic anyway.

Because it mutates a lot faster. But it has with
almost everything else we vaccinate against.

And it might end up not important anymore like the spanish flu did too.

You don’t know that either.

About what ? Most are having a real problem
getting most of their own vaccinated. Vaccinating
the rest of the world has to come later, just like
it did with every other viral vaccination campaign.

> but I see little evidence of it.

Because they are having enough trouble vaccinating their own so far.

Safer to wait for the next booster jab which should be along in the
Autumn and with a better match for the current nasty strains.

There is absolutely no chance of driving it to extinction any more. It
can already infect domestic pets, ferret and mink in addition to humans.

About one sixth of the cats and dogs in homes where the adults have
tested positive for Covid have also tested positive for Covid
antibodies. Recent results suggest it is catholic in what it infects:

It is never going away.

Yes, it is an OK thought and may have some merit...

But so far, there is no need to do that. The mRNA vaccines work just
fine against variants so far.
