But together, their data strongly suggest the vaccines will be much less effective at stopping infections from the omicron variant but will still likely offer protection against severe disease. The study in Germany also indicates that a third shot, or a booster, will partially recover the effectiveness of the vaccines, at least for a few months.
In the South African study, researchers at the Africa Health Research Institute took blood from about a dozen people who had been vaccinated with two shots of the Pfizer vaccine and looked to see how well their antibodies kill the virus. In the experiment, everyone's antibodies were able to neutralize an earlier version of the virus quite well.
