The universe has a sick sense of humor.
Actress, model, author, and former Playboy Playmate Jenny McCarthy has been tirelessly promoting anti-vaccination rhetoric since 2007. Jenny McCarthy's irresponsible pseudo-science has been spewed on numerous television appearances and through numerous books and articles urging parents not to vaccinate their kids. It is not hyperbolic to state that Jenny McCarthy may have indirectly led to the deaths of hundreds of children (see Jenny McCarthy Body Count).
Fast-forward to February 3rd at the Playboy Mansion, where as many as 200 people fell victim to Legionellosis at a party for Jenny McCarthy's Generation Rescue Autism Foundation. Legionellosis can take two distinct forms: Legionnaires' disease (the more severe form of the infection) and Pontiac fever. Although authorities have not pinpointed the source of the outbreak, it is believed it could have been spread by the Playboy Mansion's hot tub, or by a fog machine at the party.
The difference here is that any dummy knows that vaccines don't cause Legionellosis. That and the fact that nobody has died from this outbreak.
