Whooping Cough is sweeping the U.S. in a way that hasn't been seen in decades. In California, nine babies have died. Indiana has more cases than it's seen since 1986.
The most vulnerable victims are babies too young to be fully vaccinated, like the ones who died in California. In the past, they were protected by a firewall of vaccinated people around them. That is why public schools require vaccinations -- not just to keep your kid from getting sick and missing school, but to keep your kid from spreading contagious diseases to those who are too young or too immune-compromised to be vaccinated.
In recent years, a discredited quack has spread misinformation blaming vaccines for the rise in autism diagnoses. D-list celebrity Jenny McCarthy, whose son has autism, has bought into the quackery and used her celebrity soap-box to brainwash other parents into not vaccinating their kids.
Taking medical advice from Jenny McCarthy is a lot like letting Viscount Monckton influence energy policy.
