The specific neurological disorders that were claimed to be connected to the MMR vaccine are encephalitis and aseptic meningitis. The study had a total of 535,544 children ages one through seven. They were all immunized between 1982 and 1986. The study showed no correlation between the two. Even so, this did not stop the rumors associated with the MMR vaccine. (aap.org)
One example the many myths would be that a baby’s immune system could not bear so many immunizations. This is false. All evidence suggests an infant could take up to 10,000 vaccines in one sitting. This is due to the amount of antibodies that are in the baby’s blood and the rate that the baby’s cells are regenerating. Exposure to the infant on a daily basis, is more than if they were given the vaccine.
Another common myth made about vaccines is that natural immunity is better and safer than immunity from the vaccines. There is belief that natural immunity causes a greater immunity to the disease. This is not true and can also be more risky than beneficial. The chances of someone dying due to measles is about 1 in 500, while the death rate that is caused by an allergic reaction to the MMR immunization is less than 1 in 1,000,000.
