It’s not exactly random, it includes Robert Melone who is early researcher in the mRNA technology who was part of a team that got some patents but he likes to call himself the inventor of everything mRNA.
So the guy somehow got bitter with the people involved and turned it into media battle. He tries to portray himself as an insider who is not afraid or has higher morals to tell the truth about mRNA.
He says stuff like “This research shows that virus spike proteins damage the heart, the vaccine produces spike proteins therefore vaccines are dangerous”.
Doesn’t have any actual research on his claims, he simply invents things from thin air and says them from the position of inventor of the mRNA.
Very popular guy in the antivaxx community.
