So, what are your news or personal site/blogs (maybe Twitter accounts?) you rely on?
One guest made an interesting point, you should use medical papers more as a guide what not to do than what to do, negative effects are more reliable due to the constraints in studies
. . .
How do you know whether it's reliable or not? Or do you mean that reliably supports a non-medical worldview one way or another?
Interesting framing, as if looking for nuance in "reliable" health info that -- implied by your example -- would include info "against vaccines" when being against vax tends to suggest either anti-science or perhaps a preference to go back to survival of the fittest, when measels, mumps, rubella, helped cull weak kids in challenged communities. Where's the nuance in that?
Maybe you meant against boosting immunity with mRNA tech to smooth SARS-COV pandemic spread? Sure, that's nuanced. But you wrote pro or against vaccines in general.
If you're unhappy that anti-vax material isn't as widely published, consider that could be because it's not as widely valid, so doesn't withstand peer review or other scrutiny. Perhaps given the facts scientifically in evidence, an absence of such nuance suggests the publisher may not be more political but simply more "reliable".
