The paragraph below came from an article by the FDA. The full article is in the link below.

...The FDA’s job is to carefully evaluate the scientific data on a drug to be sure that it is both safe and effective for a particular use, and then to decide whether or not to approve it. Using any treatment for COVID-19 that’s not approved or authorized by the FDA, unless part of a clinical trial, can cause serious harm. (emphasis mine)

Now think about this. The vaccines they are using for Covid-19 are NOT FDA approved. So therefore whoever takes it, is part of a clinical trial. So why are they trying to get the entire country to participate in a trial? And what if they determine in the future that it's not nearly as safe as they thought it would be? What becomes of the people who took it?
