I know what you mean. I've been posting health and science stories for almost 9 years. But not all the anti-vaccine rants are bunk.
Tetanus vaccine may be laced with anti-fertility drug. International / developing countries.
Since I was a kid, I heard about “activist science” out of the Left. I had a teacher talked about it. As I recall it was in social(ist) studies - the soft sciences.
But I think it has spread now with the introduction of humanism (moral realitivity) into medical schools/hard science/research. The truth is not relative in Western science...but it is humanist “science.”
We learn all the time that theories are facts and only knuckle dragers dare to question liberalism’s/humanism’s “science.” They all went along with algore’s man made climate science...even though it left out the Sun and ignored ancient climate chage.
Once socialists tamed their independence and analytical ability to speak and think independently in a “bush hates science” head nodding frenzy, socialism ensnared them into socialized medicine. Federal grant and contract funding control was bad enough, but they had their own somewhat independent institutions and businesses in the name of medicine. They are totally owned now.
That abstract you linked was not an indictment of vaccines, but a description of people committing deliberate evil. Unfortunately, using the practice of vaccination to hide/commit nefarious acts has the effect of making people distrust a valid public health effort, with the long-term effect that fewer people receive vaccine protection, and more people die of preventable diseases. All of that actually does fit the radical left agenda (those who would decrease human population by any means possible).
As for scientific illiteracy on the right, we have, right here in this thread, posts #27 and #30 demonstrating the kind of scientific illiteracy that I have been trying to counteract for years.
