Omicron

Dec 10, 2021 11:36

An early study of vaccine effectiveness showed that the shots from AstraZeneca Plc and the Pfizer Inc.-BioNTech SE partnership provided much lower defenses against symptomatic infection with omicron, compared with the delta strain, after two doses. A booster lifted protection to 70% to 75% in the early days after the shot.

теперь в сравнении появилось слово "симптоматических", от них две дозы тоже не защищают. упоминается также, что АЗ вообще в ноль
