My (33F) friend (33F) is being used for propaganda and I don't know how to reach out to her about it

My friend got a really, really, bad side effect that can happen with injections and is extremely rare - unfortunately the injection that gave her the side effect is the J&J Covid vaccine. She has been posting about it on her personal social media, but it looks like her posts are being shared by a VERY OBVIOUS propaganda blog (it calls the J&J a "DNA vaccine", includes links to buy Ivermectin and Hydroxychloroquin, there's a page about how masks are evil, etc.; if this were a relatively unbaised news article I would be less concerned, but it's definitely not). This blog is the second result when you search her name. She has a reasonably public life with businesses under her actual name - these are all below the propaganda piece in question in the search results.

I want to reach out to her to make sure she's aware (working under the assumption that she doesn't know/didn't authorize this) because it's both very harmful propaganda by itself and could hurt her business - I know I would be not feel safe hiring her if I saw this and assumed it was OK'd by her. I know we have differing political beliefs (she's Christian and I think leans soft right; I'm queer, very far left, pagan) so I'm afraid my default reaction is colored by politics. I'm pretty good IRL at talking to people from all backgrounds and persuasions usually, but I'm a bit stumped here. I think mostly it's because I'm afraid of losing her because she's my oldest friend and her parents are like second parents to me - I've known her since I was a couple hours old. We've drifted apart for a couple decades but I am afraid to lose what is left. Reddit, how should I approach this?

(If it matters I'm vaccinated, doing fine, and eagerly awaiting my booster).

tl;dr: My friend got a rare side effect from an injection and is being used for outright dangerous anti-vax propaganda. I want to warn her but I don't know how to approach due to our differing backgrounds.
