In the decade before the live measles vaccine was licensed in 1963, an average of 549,000 measles cases and 495 measles deaths were reported annually in the United States. However, it is likely that, on average, 3 to 4 million people were infected with measles annually; most cases were not reported. Of the reported cases, approximately 48,000 people were hospitalized from measles and 1,000 people developed chronic disability from acute encephalitis caused by measles annually.

Pneumonia is the most common cause of measles-associated death in children; it occurs in approximately 6 percent of cases [4]. Respiratory tract infections occur most frequently among patients <5 years and >20 years of age.
Pulmonary complications of measles virus infection include bronchopneumonia, laryngotracheobronchitis (croup), and bronchiolitis [6,18]. Measles has also been associated with development of bronchiectasis, which can predispose to recurrent respiratory infections [18]. Bacterial superinfection may occur in up to 5 percent of cases.
Neurologic complications associated with measles include encephalitis, acute disseminated encephalomyelitis and subacute sclerosing panencephalitis.
Acute measles-induced encephalopathy has been described in the setting of human immunodeficiency virus infection; this manifestation is rare [32].
Encephalitis — Encephalitis occurs in up to 1 per 1000 measles cases... Approximately 25 percent of children have neurodevelopmental sequelae; rapidly progressive and fatal disease occurs in about 15 percent of cases
ADEM Acute disseminated encephalomyelitis (ADEM) is a demyelinating disease that occurs in about 1 per 1000 measles cases. ADEM following measles infection is associated with a 10 to 20 percent mortality [33]; this is higher than mortality from ADEM due to other causes (up to 7 percent) [36]. Residual neurologic abnormalities are common among survivors, including behavior disorders, mental retardation, and epilepsy
SSPE is a fatal, progressive degenerative disease of the central nervous system that usually occurs 7 to 10 years after natural measles virus infection. Its pathogenesis is not well understood but may involve persistent infection with a genetic variant of measles virus within the central nervous system [8,37].
Between 1960 and 1974, the estimated incidence of SSPE was 8.5 cases per million cases of measles. Between 1970 and 1980, the incidence fell to 0.06 cases per million; the decline paralleled the decline of measles cases as a result of vaccination (with a lag time of several years) [38]. Data derived from the resurgence of measles infection in the United States between 1989 and 1991 suggest that the risk of SSPE may be 10-fold higher than originally estimated, based on follow-up study of cases of biopsy-proven SSPE [39].
Donald Trump on Vaccines:
I’m not against vaccinations for your children, I’m against them in 1 massive dose.Spread them out over a period of time & autism will drop!

No more massive injections. Tiny children are not horses—one vaccine at a time, over time.

I am being proven right about massive vaccinations—the doctors lied. Save our children & their future.

Healthy young child goes to doctor, gets pumped with massive shot of many vaccines, doesn’t feel good and changes - AUTISM. Many such cases!

Lots of autism and vaccine response. Stop these massive doses immediately. Go back to single, spread out shots! What do we have to lose.
