I doubt it.
“Knowingly filing a false VAERS report is a violation of Federal law (18 U.S. Code § 1001) punishable by fine and imprisonment.”

Cocaine, robbery and murder are illegal too.
Doesn’t seem to stop anyone.
That makes me chuckle. You can’t file a false Vaers report without the law coming down on you, but they can stab you with an experimental concoction and suffer no consequences if you end up injured or dead. Hell of a deal.
