I don't know ryandamm, so I can't judge whether he is pro- or anti-vax, but you should be fact checking every article before sharing it.

Doing basic checks like "what else did the authors publish" seem fairly sensible.

Actually it isn't really since the scientific community regularly has the problem of ostracising those that offer much progress. It is a decent method in practice but ultimately fallacious. The corpus of published works is far too massive so it is a compromise. A bad one, because the pressure to publish has a negative effect on scientific rigour.
