I'm reluctant to leverage such language, but this is an
appeal to authority. And there's tons of historical evidence that
authorities failed to produce their predicted end without regard to their field, specialty, education, politics, etc... So to acede to this solely on the basis that the "intelligentsia" has is perhaps just as blind a means as a coinflip. And there is of course a plenitude of arguments about how politicized this has all become, vested interests, the bandwagon, what someone might call drinking the Kool-Aid. Not to mention at this point in history we're dealt with so much information that unless your specialization is intersecting with, let's say, molecular biology, you're not particularly well suited to make a judgement call. So all these physicians, whose practice is far removed from the infinitesimal nuances of the field may not be wholly capable of assessing the finer nuances, so they trail the authorities that dictate the policy to people ever further removed. And the whole of the field isn't unanimously pressing for vaccination either, there are fringe elements that are duly skeptical who do lay within your "physicians, medical researchers with PhDs" milieu [1]. Not to mention we need a control group, how will the vaccinated gloat if they've nobody to tell "I told you so..."? And, as an example, recently there was paper published showing indications that antibiotics can cause developmental abnormalities due to alterations within the gut-brain axis which alters gene expression. Penicillin was discovered in 1928, 93 years ago, and we're just now finding out that might carry adverse effects when deployed in the young, a practice long unquestioned [2]. That's just an example to wrap your head around. And there's a litany of legitimate philosophical questions that haven't been asked because we're so well conditioned to being dragged along by technology rather than taking the reigns ourselves, and that's where my predominate concerns lie.
