The best time to reopen would have been June or July 2023, since the summer is more forgiving, said Liang Wannian, an epidemiologist-turned senior official leading China’s Covid response, in an interview with state television on Monday. However, immunity generated from vaccinating the high-risk elderly would have ebbed, he said.
The summer of 2022 wasn’t a good time to reopen since elderly vaccination rates then were low, he said. Immunization has since climbed to 80%, offering more protection, he said.
