Pfizer vaccine doesn't remove the need for therapeutics, especially for the first half of 21. However, if it (or other vaccine) works, it will reduce the long term demand. We need LL yesterday, but we won't have a shot until March or so. That's just the math on getting results- which will still be interim- for our CD12. From a business revenue perspective, we are potentially cut the market significantly, and don't forget that there are other therapeutics who will likely beat us to approval, so that pie gets sliced again. We can help, but it's not going to be a blockbuster it could have been if available today.
43,000 already took the vaccine and the DSMC didn't stop for safety. I'd take the shot without another thought. Of course we have measles outbreaks in the anti-vax communities here in 2020.
