I am beginning to wonder why we have so many Covid cases with so many people vaccinated.
How many "breakthrough infections" are being recorded daily. Is it with people who got the AstraZeneca vaccination?
Why aren't we being told this information?
I'm a bit surprised about the rising cases myself given that we're coming out of summer, we still have many measures in place and we have large numbers vaccinated, and while the vaccines don't block transmission 100% the early indication were that it significantly reduced it. The delta variant has changed the rules of the game.
Why aren't we being told? Well, you are assuming we have even this information?
Information is still being collated on how the various vaccines fare versus the delta variant, but from the information in other countries there's nothing to suggest someone fully vaccinated with AZ is noticeably different than Pfizer or Moderna in protection.
In Israel, who were something of a trial country for Pfizer, there seems to be some concern that the protection given from Pfizer is dropping after 6 months and they are planning booster shots.
For all we know, AZ might afford longer term protection.
Given that the Janssen/Johnson&Johnson vaccine is single dose, that would be the one I'd be most concerned about versus delta variant.
If anyone should be targeted for booster doses, they seem to the ones who should be prioritised if over 50.
It's not authorised here, but there seems to be some indication that the Chinese vaccines are faring poorly versus the Delta variant.
The Russian Sputnik seems to hold up well, assuming you get a proper batch of it!
