Zerohedge CDC Covid-19 Vaccine Article Shadowbanned By Facebook

Why does sharing this article to Facebook trigger the social media giants Vaccine Hesitancy algorithm? Seems to me Zerohedge is a credible news source. Let the people read the articles and draw their own conclusions! What are your thoughts about Zerohedge? Seems credible to me. FWIW I've had my first shot of the Phizer vaccine and the next day had a fever of 101 and a bad headache. I'm scheduled to return on the 16th for the second. Debating whether I should get it or not. Your suggestions?
