My brother took the shitty useless Moderna Mrna vaccine and I think that he is about to experience complications due to Mrna poisoning.

Both my retarded parents and shithead brother are ignoring advice to have the stupid bastard medically monitored and believe everything I say is a conspiracy theory because they consume a shit ton of regressive leftist propaganda regurgitated by the Mainstream Media.

I should also note my father took some unknown vaccine but experienced no visible symptoms and the stupid bastard never checked what he took and refuses to answer when asked.

What should I do?
