Measles Mania

Measles is a contagious disease caused by a virus that affects the respiratory system, skin and eyes.

Complications from the disease are unlikely, and previously healthy children usually recover without incident. However, measles can be dangerous in populations newly exposed to the virus and in malnourished children living in undeveloped countries.

A measles vaccine was introduced in the 1960's, and it was combined with vaccines for mumps and rubella in a single MMR shot.

People who are vaccinated against measles can still get the disease, and measles can be transmitted from a fully vaccinated person to other fully vaccinated individuals.

Measles vaccine failures cause outbreaks of the disease, raising “important questions concerning the relative contributions of vaccine failure versus failure to vaccinate.”

Loss of immunity after receiving the MMR vaccine, combined with viral shedding, may spread disease and prevent herd immunity:

If wild virus can be spread via individuals with subclinical infections, it is doubtful whether population immunity (herd immunity), which is necessary to eliminate the three diseases, can be attained in large populations.

Fevers induced by measles vaccination are related to the replication and shedding of the live vaccine virus, “showing that subcutaneous injection of an attenuated measles strain can result in respiratory excretion of this virus.”

Only molecular genotyping can distinguish between wild-type and vaccine-related disease.

Emergency room visits are significantly more common in children who recently received the MMR vaccine:

There are significantly elevated risks of primarily emergency room visits approximately one to two weeks following 12 and 18 month vaccination.

Young children have an increased risk of requiring emergency care after MMR. This is especially true for girls, who “may have an increased reactogenicity to the MMR vaccine.”

Vaccine-related deaths have been associated with mumps as well, as a study has observed "devastating neurological complications associated with the detection of live-attenuated mumps virus in the brain of a child."

A toddler who developed severe neurological symptoms including blindness associated with chronic encephalitis and died following MMR vaccination was found to have vaccine-derived mumps virus in his brain.

Contracting diseases like measles and mumps naturally in childhood may have lifelong health benefits, including a significant protection against heart attacks and strokes during adulthood:

Measles and mumps, especially in case of both infections, were associated with lower risks of mortality from cardiovascular disease.

The results of this study may be explained by the hygiene hypothesis, which proposes that infections suffered during childhood are necessary for normal development of the immune system.

Many autistic children have elevated levels of antibodies to the measles virus but not to other viruses. “An inappropriate antibody response to MMR, specifically the measles component thereof, might be related to pathogenesis of autism.” As a result, a large number of autism cases may stem from neurological symptoms due to an atypical measles virus infections following MMR vaccination.
