symptoms. the key, as i understand it from talking to doctors today is that you have to get your hands on this pill and take it very early on in your illness. meaning if you wait any time more than five days, there s really no evidence it s going to help you at all. is that right? that s right. so what happens is the virus attaches to the lining of your nose. multiplies thousands of times. at that point, virus replication is an important part of the disease profess. then immune response kicks in. that s when you develop symptoms. at that point, virus reproduction is not an important part of the disease processing anymore. so anti-virals or mono clonals don t work anymore. you have to get it early to have an effect. you ve been talking about booster shots. you said you re concerned that this emphasis on boosters at the exclusion of all else is misguided.
