[quote JanglyBeads]Some actual data from Israel:

That's really interesting, and pretty encouraging, data, albeit very preliminary. Suggests good news for the Pfizer- vaccinated - only a slight drop in efficacy against either infection or serious disease - less than the difference between Pfizer and AZ - so if true this would mean Pfizer still works better against Omicron than AZ does against Delta. I presume there's not so much data on AZ as it wasn't used so much in South Africa (because less good against beta wasn't it?)
On the negative side, the article suggests that unvaccinated people have 2.4 times the chance of serious illness - which is a lot. Would sggest we need to get kids vaccinated asap, and also appeal to unvaccinated adults urgently.
