Past vaccine disasters show why rushing a Covid-19 vaccine now would be 'colossally stupid' - CNN A 'colossally stupid' move Markel said people's mistrust of the system makes the idea that the FDA would rush this process before late stage clinical trials are complete "colossally stupid." "This is one of the most ridiculous things I've heard this administration say," Markel said. "All it takes is one bad side effect to basically botch a vaccine program that we desperately need against this virus. It's a prescription for disaster." FDA Commissioner Hahn said that the vaccine decision will be based on data, not politics, but Kinch shares Markel's concern. "This could do substantial damage," Kinch said. Kinch, who is a patient in one of the vaccine trials himself, said the clinical trial process needs to be followed to the end. A too-early EUA for a vaccine could cause a "nightmare scenario," for a few reasons. One, the vaccine may not be safe. Two, if it is not safe, people will lose faith in vaccines. Three, if a vaccine doesn't offer complete protection, people will have a false sense of security and increase their risk. Four, if a substandard vaccine gets an EUA, a better vaccine may never get approval, because people would be reluctant to enroll in trials and risk getting a placebo instead of a vaccine. "People are going to die unnecessarily if we take chances with this," Kinch said. "We've got to get this right."
