The point moke, which seems to elude you is not that no one should take the vaccine but that there is no long term data yet on the COVID vaccine so while it is certainly worth the risk for people in higher risk categories, it is not worth the risk if you are in a category that will with 99.99 percent probability survive with no ill effects if you catch the virus.
Trump asked Congress to include legislation in the relief bill that would indemnify businesses from being sued over COVID. You can never know where you contracted the disease so of all the places you visited in the prior two week, people will pick the option with the deepest pockets. It's not like black lung disease or mesothelioma where you need exposure to some element to get a disease that can't be found everywhere and either you worked in a coal mine or you didn't. You can't get black lung by shopping in the company store. You didn't get black lung disease at Disney World.
Last year we (my condo association) never opened our pool. We are a small association and couldn't spend $200 per day to cover the cost of someone to simply stand around to enforce social distancing and make sure that the swimmers wiped the Chlorine off the hand rails when they exited the pools with "Other" bleach which apparently kills COVID that the Chlorine does not

because our Governor decided it was necessary and he is a man of science so he would know. More than half of the board members were terrified of being sued. Our lawyer's position was that they would never win the case but that it would cost us thousands of dollars to defend ourselves and our insurance had endorsements that specifically said that they would not cover Virus, Bacteria, or Fungi related lawsuits. So that covers Covid, Lyme Disease, and the ill effects of mold exposure. These endorsements have been around for several years. The Virus one was added at the time of Swine Flu, the others were added earlier and I'm sure were prompted by some lawsuit somewhere. Remember, the business model of insurance companies is to collect premiums but to avoid whenever possible paying out settlements

This, of course, is why many large companies are self-insured and only purchase what is called reinsurance. Reinsurance kicks in in tiers and always after the primary insurance pays out so it is catastrophic coverage and therefore relatively inexpensive.
But, Congress couldn't possibly do what Trump asked.
