They cause autism:
The origin of the myth was from a study by Dr. Andrew Wakefield.
Most of Dr. Andrew Wakefield's co-authors withdrew their names from
the study in 2004 after learning he had been paid by a law firm that
intended to sue vaccine manufacturers. The same year, the Institute
of Medicine reviewed evidence from the US, Denmark, Sweden, and the
UK and found no connection between vaccines and autism. Around 2010,
another British medical journal concluded Wakefield's study
misrepresented or altered the medical histories of all 12 of the
patients whose cases formed the basis of his study.
The Lancet retracted Wakefield's paper in 2010 and he lost his
medical license.
They contain poison: The cause was from a preservative
and Thimerosal is no longer used in vaccines. In 2001, the FDA
stopped issuing licenses for children's vaccines containing it. The
preservative has been used for decades and still is in adult
vaccines. There have been many studies and none of them show a
correlation with autism or other serious side effects, the FDA says.
Doctors and insurance companies promote vaccinations to
drive profits: Some insurers pay the cost of vaccinations to
prevent paying more later, when a patient gets sick. A 2009 study
found that up to a third of doctors actually lose money when giving
vaccines.
The diseases they help prevent are long gone: One example of
this effect is before the measles vaccine was introduced in the
1960s, there were between 3 to 4 million cases a year, resulting in
400 to 500 US deaths. Measles vaccination in the US has reduced the
rate of infection in the population by 99% when compared to times
when no vaccine was available. Measles has been on an uptick this
year, because so many children have not been vaccinated against it.
