They can't know the long term effects of the vaccine, Just look at other meds that worked in trials but not in the long haul. Thalidomide, treated morning sickness and deformed thousands of babies. Zantac, treated acid reflux, and caused cancer. Celebrex (Vioxx) treated pain and caused heart attacks and many other drugs. They all tested safe in short trials but were deadly in the long term. As far as the stimulus check, many seniors who are on fixed income have suffered because of the raise in grocery prices.
You have a point, but you have to believe that systems and approaches to research have changed since (in the case of Thalidomide) 1950. Celebrex remains on the market with SERIOUS guidance as to dosage. As for Zantac, it was taken off the market because of "concerns that the medication may contain a cancer-causing chemical that's also been detected in certain blood pressure medications." There are capable alternatives to Zantac, such as Nexium and Prevacid. My point is that none of *those* issues should affect the usage of this vaccine, in the sense that it's not a daily drug, it's a one-time shot and prevent mechanism.
It still may be a problem, but in my opinion, not in the same way as those you cited. My understanding is that health care workers, and first responders are to receive the first batch. As far as I'm concerned, if that roll out is successful, I'll be trying to jostle to the front of the line.
