mmrI recently turned 56 years of age and I was surprised to see that the majority of measles cases in California for the current outbreak are among older people. I’ve read that one measles patient in the current outbreak is 57 and another is 70 years old.

Vaccine GapYou’re squarely in that gap if you were born between 1957 and 1971

I was vaccinated for measles back in the 1960s, before the current two-dose-vaccination protocol became recommended, so today I went to the SCNM clinic and got a MMR (measles, mumps, and rubella) vaccination shot.

Looking to the future: what could happen in the United States?

2008–2011 measles outbreak, France

The figure above is from Measles Elimination Efforts and 2008–2011 Outbreak, France. In 2011 there were more than 20,000 measles cases in France and almost 5,000 patients were hospitalized, including 1,023 for severe pneumonia and 27 for encephalitis/myelitis; 10 patients died.

Measles and the brain

Studies indicate that about 1 of every 1000 people infected by the measles virus will show evidence of the spread of virus to the central nervous system (infectious virus can be isolated from the cerebrospinal fluid or brain). The measles virus has a lipid envelope with two glycoproteins that have been shown to be important for infection of human cells: the fusion protein (F) and the receptor-binding protein (H).

Since some people with compromised immune system function cannot be vaccinated and since some vaccinated individuals develop encephalitis, additional treatments for measles are being sought. For example, it has been demonstrated that for laboratory animals, peptides with sequences corresponding to parts (such as the C-terminal heptad repeat region; HRC) of the measles virus fusion protein can be conjugated to cholesterol and upon injection into animals can protect against fatal measles virus infection.
