Can you share what some of those medications are? Any ones that I'm aware of are products that came out 20+ years ago. And by "late night TV", if you're referring to the class action attorney commercials... well, that's all you need to know. They're just trying to get a settlement so they can pocket a few million. It certainly is possible for things to surface after a drug comes to market. How big the clinical trials are depends on the incidence of the disease. For drugs that I've worked on, the trials are typically 1000-2000 people (and there are usually 3-4 separate trials). For oncology drugs, the numbers are much smaller because of how rare the diseases usually are and how short the life expectancy is. As I've shared before, these clinical trials aren't with 1000-2000 people - they are with 30,000 people. And the reason they are coming to market so quickly is because of the tremendous amounts of resources that have been allocated to this as well as the fact that these companies are all sharing data - that never happens. I'm not afraid of the vaccine, but I won't be first in line to get it so that the health care/essential workers, first responders, and high risk populations can get first cracks at it.
