Well I do think vaccine passports represent a potentially massive assault on civil liberties, if that's what you want me to say.
But two points here:
1) If we fail to reach herd immunity, there will be recurring outbreaks of this bug until the end of time, and big ones will be dealt with by lockdowns, mandatory masks, and other measures that interfere with basic everyday freedoms - which sounds bad, right? I mean that's the stuff you really hate? And if that happens, it'll be the result of a significant number of people remaining voluntarily unvaccinated, which in turn is precisely a result of the anti-vaxx garbage your lot have been sharting out for decades.
Vaccine passports, if they come to pass, only make sense in the context of a significant number of people remaining voluntarily unvaccinated. So your freedom-warrior schtick is, in the end, entirely self-defeating.
2) There are assaults on our civil liberties happening practically on a daily basis these days. Why is it only policies that are intended to reduce the spread of a disease that get you so exercised? In case you hadn't heard, you can now get a ten-stretch for defacing a statue, and protest is now illegal if someone finds it "annoying". I don't recall hearing a peep out of you about either those outrages.
