Sitting in a webcast session now with a top doc from Discovery sharing the stats for the vaccine, in particular the Phizer vaccine is amazing. From their own independent analysis (mostly gathered against Delta to date) risk of infection seemed to be 79% down when vaccinated and change of admission or death down over 90%.
Booster shot also seems to be very helpful if one compares data between Belgium and Netherlands as they have similar patterns but Belgium has boosted their over 80's and are seeing much better results. resistance does drop off a but over time post the doses but with the booster shot of Phizer immunity went even higher than the average of just the two doses.
