There are a few Airlines that now require vaccination to remain in employment as a Front Line worker. Simple answer is that if you don't want to do it no issue. Just choose a different career as the chances or redeployment are slim to none. You have a greater chance of losing your Class 1 with a myriad of other issues and I would think that post Covid lung capacity issues or other damage would probably make that happen as well. Rule #5 though says "Don't take medical advice from a Pilot" so Caveat Emptor. In the end make your own decision and own the outcome.
