Omicron:

A report out of South Africa offered a first glimpse at how vaccinated people might fare against the fast-spreading Omicron variant of the coronavirus.

Laboratory experiments found that Omicron seems to dull the power of the Pfizer-BioNTech vaccine, but also hinted that people who have received a booster shot might be better protected.

The study, published online on Tuesday, found that antibodies produced by vaccinated people were much less successful at keeping the Omicron variant from infecting cells than other forms of the coronavirus….

Dr. Sigal and his colleagues used antibodies from six people who received the Pfizer vaccine without ever having had Covid-19. They also analyzed antibodies from six other people who had been infected before getting the Pfizer vaccine.

The researchers found that the antibodies from all of the volunteers performed worse against Omicron than they did against an earlier version of the coronavirus. Overall, their antibodies’ potency against Omicron dropped dramatically, to about one-fortieth of the level seen when tested with an earlier version of the virus. That low level of antibodies may not protect against breakthrough Omicron infections.…

The results could help explain some high-profile superspreading events caused by Omicron. At an office Christmas party in Norway, the virus seems to have infected at least half of 120 vaccinated attendees.…

His team found a distinct difference between the two sets of volunteers. The antibodies from the six uninfected vaccinated people were very weak against Omicron. But among the volunteers who had Covid-19 before vaccination, five out of six still produced fairly potent responses.

One reason for the difference is that people who are vaccinated after an infection produce higher levels of antibodies than do people who were not infected.… nytimes.com
