The thalidomide references just blow me away. People are using that as a reason to avoid a vaccine developed today, when the issues with thalidomide usage occurred in an entirely different universe of medical knowledge and study? I mean, FFS, I wasn't born yet and I'm not young, cable TV didn't exist, heck color TV wasn't yet in most people's homes. This all happened around the time that the very first televised presidential debate happened.
It has only slightly more relevance to today's medical world than does the fact that people died of bubonic plague in the middle ages.
