430 million people worldwide use Reddit.

Yep, it's less popular than Quora 😂 but the reason Reddit thinks what it does is because anyone who disagrees is aggressively banned. Everyone else has moved on and Reddit is stuck in 2020.

That's called the bandwagon fallacy btw.

others promoting equine heartworm medicine as a covid treatment

Ivermectin is a really interesting drug. To still try to disparage it by dismissing it as nothing more than horse dewormer is the most ignorant thing I've read all year. It's a useful tool for a variety of issues, maybe not covid, but the diabetes medication metformin showed fantastic results with covid. The mindset you have leads to people dying when you refuse to look past the useless covid vaccine.

because the option for a 4th or 5th booster shot is very difficult to locate

Only 30% of Americans even have one booster. 25% think the vaccine probably killed someone they know. 50% are unsure but thinks it needs to be investigated. You have a false consensus on Reddit, the views there do not reflect reality.
