Vaccine Question- What are your plans if your employer tries to force it

That's not going to work.
You have to offer them the option to promise to be fully and permanently financially responsible for any undue consequences of requiring an experimental vaccination to you without other conditions including cancer, auto immune disease or others known to be associated with this vaccine.
They will of course, refuse.
The request, under the circumstances, is only reasonable.
That's an admission that they know it's unsafe and a confirmation that you requested and were refused equitable compensation should you be harmed.
