Earlier quoted context omitted.
Not even proven side effect. Just something that might be theorized to be the effect of the vaccine. It's really haunting that exactly the same FUD that tanked safe and efficient Lyme vaccine hinders covid vaccines adoption. And people wonder why companies that make covid vaccine wouldn't budge on being exempt from litigation on the basis of percieved side effects.
The difficulty with that exemption is that either a good or a bad actor would ask for it. A good actor to avoid being the target of frivolous suits and a bad actor to have cover for their actions. Because a good or bad actor would behave the same in this respect, people bring their own conceptions to the table and see what they expect to see (in either direction).
Legally speaking, I expect the exemption says something about not lying to the FDA in the fine print, so true bad actors would not be able to hide behind the exemption either.
