Not necessarily. Like I said in other posts, wherever vaccination requirements existed we have protocols for sharing proof of antibodies. That's all that needs to happen. If you work in a hospital or want to dorm in a college, go ahead and submit your proof of antibodies.
But mandating it across the board and taking away people's opportunity to put bread on the table if they don't comply? That's not a sacrifice of some marginal amout of individual liberty - that is a declaration of war on liberty itself. The reason I say this is because it's not hard to think logically about where systems around vaccine passports will take us. A two-tiered society in which one side of tens of millions is forced out of society, ostracized, and dehumanized.
For no reason, considering we're already looking at the majority of Americans having antibodies one way or another soon. The 100 million who had past covid have superior antibodies already. Time for us to stop allowing this converastion to be framed around someone getting or not getting the vaccination.
