Thats old news isnt it?

Yes it goes from like 95% effectiveness down to like 80% effectiveness against the south african version (I think I read?).

However, thats still MUCH better than how some of the other vaccines do.

Astrazeneca vaccine drops down to like ~10% effectiveness against that variant.
Thats why South Africa is like "okay UK, we wont bother buying anymore vaccines, thank you".

This is also why I said, it was worrying that the South African variant is spreading in the UK, since most of their vaccines are from AZ.
Thus it could undo alot of the good work vaccinateing they have already managed to get done.

Yes, it's kind of old news but Reuters loves their Covid doom, so there you go.

As for those numbers, that was just the press theorizing. We don't have numbers from actual trials, just controlled in vitro studies.

For all we know, it could be a big drop comparable to Novavax's, where its efficacy dropped from 95% in conditions similar to Pfizer's phase III trials down to 50% - 60% with the South African variant. Or it could be a smaller drop of about one-fifth like it happened with J&J's single-dose vaccine.

Of course, like every expert has been trying to hammer in the minds of efficacy junkies, it's far, far easier to prevent severe disease than infection. And that all the vaccines should continue doing that very well.
