I provided the source links in another reply in this post, but, if you read the ABC article there are two statements that are noteworthy. One states that Biden is considering travel restrictions. This is an unconstitutional order if he invokes it. Second he is reconsidering how the government reimburses hospitals for people who are not vaxxed. I take that to mean he is going to prohibit reimbursement which will also domino to insurance companies who will likely also deny coverage for illnesses attributed to covid.
