Laboratory experiments with blood plasma led them to estimate that there would be 73% protection against symptomatic disease from omicron and 95% against severe infections for those who had been vaccinated and previously infected, the scientists, led by Alex Sigal, said in a preprint released on Wednesday. A preprint has not been peer reviewed.
