The average pro-science person on Facebook primarily is approached by an anti-science person looking for public confrontation. I didn't see your post, but I'd imagine looking around you could find many questions similar to yours being asked in bad faith. While I agree your question _isn't_ bad faith, the surface level hallmarks are there. Question about the expedited testing process, context includes a reason to worry about safety if there isn't a scientific answer, then concluded by anecdotes of stumped medical professionals as if to give credibility to the concerns. I'm aware that a close read of this post shows you have a genuine question, but I can also see why it blends in well in a sea of "But we don't know the vaccine is safe" posts.
