The recent outbreak of measles that began at Disneyland has led to its reemergence as a health care risk.

The vaccination of measles has becone a controversy with some parents refusing to vaccinate their children based on the erroneous reports linking the vaccine to autism.

Presedential hopeful Rand Paul went so far as ro imply that normal children have developed mental issues due to the vaccine and he is a doctor.

What nonsense!

The fact are as follows:

Measles, also called morbilli, roseola or rubeola (but not rubella or German measles) is a highly contagious viral infection and affects the respiratory system, immune system, and skin. 

The disease is caused by a paramyxovirus of the genus Morbillivirus.

Symptoms  develop 7–14 days after exposure to an infected person.

Initial symptoms include fever, Koplik's spots (spots in the mouth), malaise, loss of appetite, runny nose and red eyes. Patients may also develop a hacking cough later on after which they develop a spot-like rash that covers most of the body.

The course of measles without complications usually lasts about 7–10 days.

Measles is an airborne disease which spreads quite easily through coughs and sneezes of infected people. The virus can remain infective remaining dormant on surfaces for two hours.

The vast majority of people who share living space with an infected person will develop the disease providing they are not immune.

]After initial exposure, symptoms develop nine to twelve days later.

The period of infectivity begins around four days prior to and lasts until five days following the onset of the rash. The rash usually appears between two and three days after the onset of illness.

There is no treatment for measles.

Most, with uncomplicated measles, will recover with rest. However, should complications develop, measles can be a serious disease.

Complications include pneumonia, ear infections, bronchitis and brain inflammation, which has a mortality rate of 15%.

Measles resulted in 96,000 deaths in 2013 down from the 545,000 deaths that occurred in 1990.

In 1980, before a widespread vaccination program began, measles is estimated to have caused 15.6 million deaths per year. Most of those were less than five years old.

The measles vaccine is highly effective at preventing the disease and preventing these senseless deaths.

Since the 1990s, the measles, mumps and rubella vaccine (MMR) in the United States, has eradicated the transmission of these highly contagious, acute viral diseases.

The MMR vaccine is an immunization vaccine against measles, mumps, and rubella (also called German measles).

It is a mixture of live attenuated viruses of the three diseases, administered via an injection.

It was first developed by Maurice Hilleman while he ws employed by Merck.

The MMR vaccine is generally administered to children around the age of one year, with a second dose given before they begin school (4 or 5 years of age)

The second dose is a dose to produce immunity in the small number of persons (2–5%) who fail to develop measles immunity after the first dose.

In the United States, the vaccine was licensed in 1971 and the second dose was introduced in 1989.

It is widely used around the world; since its introduction, over 500 million doses have been given in over 60 countries.

The vaccine is sold by Merck as M-M-R II, GlaxoSmithKline Biologicals as Priorix, Serum Institute of India as Tresivac, and Sanofi Pasteur as Trimovax.

It is usually considered a childhood vaccination. However, it is also recommended for use in some cases of adults with HIV.

However, waning vaccination coverage in some U.S. communities continues to put vulnerable populations at risk.

The largest single outbreak occurred among 21 people in a Minnesota community where many parents reported concerns about the safety of MMR vaccine.
