Yes a UK doctor lied about the vaccine autism threat and it spread like wild fire.

How do crazy ideas develop? Sometimes a grain of truth like this
could be read by a screen writer and base a comedy series BRAIN DEAD https://www.imdb.com/title/tt4877736/
about a parasite causing the brains of consevatives to go insane, to one day 2 years later turning into the magic parasite killing Ivermectin to be a cure for Covid.
I am kidding about this series of events but all it takes is one little lie to capture millions.
