Tuskegee was a long time ago and is very well known here, and isn't a good reason to avoid offering the entire population some kind of proof-of-vaccination, passport or other. Instead, making sure that today's individuals from all ethnic and racial groups have equal access and good information. Transparency is called for. Before that happens, though, a couple of major federal laws have to pass that render toothless all of the GOP legislation popping up in states that is designed to exclude and disenfranchise voters. So the goal for all sorts of other fair laws coming into place is to get rid of the filibuster. And there are two senators who steadfastly want to hold their seats so are not agreeing to vote to remove the filibuster. Some things are larger than those jobs, but you need to convince them of that. There have been people who knew it would work against them who still voted to approve valuable legislation, but that kind of altruism is rare.
