And (as we’ve discussed many times!) there is very little data on post 21 day results of one dose as most of the trials were done on a different schedule.Throw in the varience in protection after 1 dose, going from memory isn’t the range between 59-89% in clinical trials.
I can understand people being frustrated with the scientists but I honestly don’t envy them given the shakiness of the data we have to date, especially after B.1.117.
