你是医学界的？从机理上怎么能看出5天后服用没有用？

机理：Paxlovid is an antiviral medication that is made of two drugs: One blocks a key enzyme that the covid virus needs to replicate, and the second blocks the first drug’s metabolism in the liver so it doesn’t leave the body as quickly. 

是的对于seriously ill 试验结果不理想。

Paxlovid is not recommended for people who are unlikely to get seriously ill from covid. In June, the drug’s manufacturer, Pfizer, announced it was discontinuing a clinical trial for standard-risk people because Paxlovid didn’t significantly reduce hospitalization and death in that group.

所有跟帖：
