Your statement: "AVAN will only go up if Kennedy is given this vaccine."
What IF Kenedy is not given the vaccine, what if he is given the vaccine and we never find out, what if he is given the vaccine and he's one of the few that doesn't respond to the treatment as well as the mayority, even if he is given the vaccine we won't find out for months.
You can not pretend that Avant's future will depend on one patient. I surely hope he (Kenedy) gets well, and if Avant/Celldex/CDX-110 has something to do with it, more power to it. But, Avant's success will depend on the hundred of thousands or millions it could and most likely will help over time, not just on one person.
