Jeremy P. Shapiro, a professor of psychology at Case Western Reserve University, has an article on The Conversation about one of the main cognitive errors at the root of science denial: dichotomous thinking, where entire spectra of possibilities are turned into dichotomies, and the division is usually highly skewed. Either something is perfect or it is a complete failure, either we have perfect knowledge of something or we know nothing.
Currently, there are three important issues on which there is scientific consensus but controversy among laypeople: climate change, biological evolution and childhood vaccination. On all three issues, prominent members of the Trump administration, including the president, have lined up against the conclusions of research.
This widespread rejection of scientific findings presents a perplexing puzzle to those of us who value an evidence-based approach to knowledge and policy.
Yet many science deniers do cite empirical evidence. The problem is that they do so in invalid, misleading ways. Psychological research illuminates these ways.
[...] In my view, science deniers misapply the concept of “proof.”
Proof exists in mathematics and logic but not in science. Research builds knowledge in progressive increments. As empirical evidence accumulates, there are more and more accurate approximations of ultimate truth but no final end point to the process. Deniers exploit the distinction between proof and compelling evidence by categorizing empirically well-supported ideas as “unproven.” Such statements are technically correct but extremely misleading, because there are no proven ideas in science, and evidence-based ideas are the best guides for action we have.
I have observed deniers use a three-step strategy to mislead the scientifically unsophisticated. First, they cite areas of uncertainty or controversy, no matter how minor, within the body of research that invalidates their desired course of action. Second, they categorize the overall scientific status of that body of research as uncertain and controversial. Finally, deniers advocate proceeding as if the research did not exist.
Dr. David "Orac" Gorski has further commentary on the article. Basically, science denialism works by exploiting the very human need for absolute certainty, which science can never truly provide.

I love how our original poster appeals to authority and then is likely the one that marked the above as "flamebait" when it turns out the science isn't as clear has presumably thought. Oh the nature of discussion today.

Reporting what the most authoritative figures on Earth say about vaccines is hardly "parroting conspiracy theories"?
Researchers do not say vaccines are perfectly safe. There's lots of nasty correlations that we cannot comfortably reject or accept. The reason you take vaccines is not because they are inherently safe but because they are safe enough to justify taking.
And I think this is where all the conflict arises. People who are not aware of the data think that "science" claims that vaccines are perfectly safe. They are not. People who find they are not think it's some huge revelation. It is not.
If people were simply honest and emphasized what and why we take vaccines, I think there'd be a lot less misinformation, distrust, and ranting at each other.
