VERY prelim data on neutralization of Omicron
Bottom line: 40 fold drop in neutralization
Not great. Not terrible.
More evidence that 2 shots probably not enough
But those with prior infection 2 shots do better
Gives me hope boosters will protect people against infections
~40x reduction in neutralisation between D614G & Omicron, reduction expected considering mutations
Key thing to stress is data is small, but looks like we don't lose complete neutralisation in those with x3 antigen exposures (eg infection 2 doses) =confidence to boosters working
