Article makes claim X. Readers of article say it makes claims X, Y, and Z. Independent fact check puts a stamp on article saying "This doesn't say Y and Z", but to most people, who will for the same reason share an article after only reading a title or a little blurb their friend wrote, will write off the article as flawed or fake news because of the fact check stamp.
Not really sure what a good solution to this is, other than to "fact check" people's posts on facebook, as well as the links they share. So maybe this link can be shared without the fact checked stamp among epidemiologists on facebook, but Bob's anti-vaxx group may get fact check labels when they try to summarize what is in the article.

says who?
"Intended for healthcare professionals" - it literally says so above the page header.
Edit: maybe fact checking systems need to label certain things as "This is a publication from a narrow domain venue intended for professionals. Specialized domain knowledge may be required to derive correct conclusions." instead of fact checking only the first few paragraphs using common journalistic standards because "users on social media only saw this title, description and thumbnail[...]".
