HONG KONG, Sept 22 (SCMP): A second wave of Covid-19 infections in China over winter is “inevitable” and until a vaccine is available there could be further outbreaks in the country, according to an infectious disease expert.
But Zhang Wenhong, director of the infectious disease department at Huashan Hospital in Shanghai, said even if a safe and effective vaccine was developed, it could be at least a year before it is widely available, according to news website The Paper.
