When Pseudoscience Becomes the Norm
In 1998, British journal
The Lancet published research by Dr. Andrew Wakefield that purported to show that the measles, mumps, and rubella (MMR) vaccines caused autism in some children. The study was widely reported and the information spread like wildfire among parents, especially those with autistic children.
One of the loudest broadcasters of this supposed link between vaccines and autism is actress Jenny McCarthy, who has campaigned in support of Wakefield's findings as recently as 2011.
The problem with Wakefield's study, however, was that it relied on faulty data. Later investigations have shown that Wakefield was set to benefit from lawsuits based on his research. The study was retracted after numerous other scientists could not replicate his findings.
Since then, no other medical research has shown a link between vaccines and mental disorders. Nevertheless, many parents still hold reservations about vaccinating their children. Wakefield’s paper has been linked to declines in vaccination and a corresponding increase in measles cases.
In March, the U.S. Centers for Disease Control and Prevention (CDC) released a study showing that an aggressive vaccination schedule does not contribute to an increase in autism incidence.

There are, however, a few real reasons why certain children should avoid vaccinations; specifically, those who are undergoing medical treatment or are still too young.
Outbreak Clusters Appear Among the Unvaccinated
Earlier this year, researchers confirmed that a 2010 whooping cough outbreak in California, the nation's worst in over 50 years, was spread by children whose parents applied for non-medical exemptions to school vaccination requirements, many for religious reasons.
The study showed that more cases of whooping cough occurred in the clusters of unvaccinated children than not, resulting in 9,120 instances of the disease and 10 deaths. In San Diego county alone, there were 5,100 exemptions and 980 whooping cough cases.
In August, the Texas megachurch Eagle Mountain International Church made headlines after 21 members of its congregation contracted measles. Coincidently, the outbreak occurred during National Immunization Awareness Month.
Following the outbreak, the church
hosted vaccination clinics and urged its members to attend.
The church, part of Kenneth Copeland Ministries, advocated abstaining from vaccinations over fears that they can cause autism. The outbreak was traced back to a church member who had traveled abroad on a mission trip and then spread measles among the unvaccinated congregation.
