By which definition? There are a lot of people that doubt effectiveness or risk-reward benefits of some vaccines, and choose not to take them by themselves for one reason or another. There are much less people that oppose any medication called "vaccine" on general principle, just because it is called so. Conflating all variety of people's opinions about all variety of medications called "vaccines" into a binary "for-against" choice and establishing a tribal barrier that discards everybody with a wrong value of the bit as "conspiracy" is a useless exercise for anything except making yourself feel better because you have the right bit value, not like those idiots. And of course, for each new vaccine, its merits must be debated, and its risk-reward profile (no medication is ever without risks) needs to be discussed on merits. Saying it can not and should not happen only paints you as a quasi-religious zealot who would refuse to even look at facts and consider them - that's not how science is or should be done.
