Great credit to this team for quickly getting us Omicron lab neutralization data. The bright side is that there is incomplete immune escape from vaccination👍

For people who had Prior Covid plus vaccination, the preserved Omicron neutralization level (FRNT) likely reflects solid protection. Not seen with 2 doses of Pfizer vaccine, but would expect that a 3rd shot, with its marked effect on raising nAbs, would simulate that

Here are some relevant data for the small sample. The 6 vaccinated individuals range from 10-39 days post-vaxx.

Take home point is how powerful hybrid immunity (vaccine + prior Covid) vs all variants that we've seen now, including Omicron

A 2nd neutralization report today using an Omicron pseudovirus (above was with live virus) and less extensive immune escape, as explained here
