Vaccines against the mutant strains of COVID-19 should be approved for use as soon as possible, said Gao Fu, former head of the Chinese Center for Disease Control and Prevention (CDC), in response to the public's concerns about the epidemic situation in China.
... Gao also advocated that the approval procedures of COVID-19 vaccines should refer to that of the influenza vaccines. If the vaccines come from the same company and use the same technology, as long as they just differ in strain or gene sequence, there's no need for them to go through the whole clinical trial process. Only phase I trial would be enough for approval, he said.
... According to Gao, humans getting vaccinated forces the virus to mutate. On the one hand, vaccination can prevent deaths to some extent; on the other hand, the immune barrier created by the vaccines will allow the virus to escape and cause the emergence of new strains.
