Consequences of not vaccinating–Report 3
If you don’t follow the news out of Wales on a regular basis, then you might not know that that there is an epidemic of measles in that part of the UK. According to Public Health-Wales, there have been 886 cases of measles from 1 November 2012 through 22 April 2013. This compares to around 0-3 cases per year in the late 90′s and early 00′s. The numbers have slowly risen to peak at 159 cases in 2009. The slow increase in number of measles cases correlates with the drop in MMR vaccine uptake to around 89% by age 5, far below the 95% level that Public Health-Wales has established for MMR vaccinations.
Measles (also called rubeola, not to be confused with rubella, or German measles) is a respiratory disease caused by the measles virus. Measles virus normally grows in the cells that line the back of the throat and lungs. Measles is spread through respiration (contact with fluids from an infected person’s nose and mouth, either directly or through aerosol transmission), and is highly contagious—90% of people without immunity sharing living space with an infected person will catch it. There is no specific treatment for the disease.

Consequences of not vaccinating a child–Report 2
Angelina at five, just before onset of SSPE
I am creating a new series, “Consequences of not vaccinating a child”, documenting individual or large group cases, where children are specifically harmed by not being vaccinated. I first published this story in May 2012, but I thought it would be fitting to republish it now, along with some updates.
One of the memes of the vaccine denialists is that childhood diseases, like measles or whooping cough, are not dangerous. In fact, some parents have set up “pox parties” to deliberately expose their children to these diseases, because anti-vaccine lunatics believe (with all evidence against their beliefs, typical of any science denialist) that natural immunity is better than a vaccine induced immunity. Not only is that an Appeal to Nature fallacy, but it shows ignorance on how immunity occurs.

There is no specific treatment for the disease.
Even though vaccine denialists will claim that measles is not dangerous, not backed up with evidence, it is actually a fairly dangerous disease. According to the CDC, some of the complications of measles are:
About 30% of measles cases develop one or more complications, including:
- Pneumonia, which is the complication that is most often the cause of death in young children.
- Ear infections occur in about 1 in 10 measles cases and permanent loss of hearing can result.
- Diarrhea is reported in about 8% of cases.
These complications are more common among children under 5 years of age and adults over 20 years old (usually those with lapsed immunity).
Even in previously healthy children, measles can be a serious illness requiring hospitalization. As many as 1 out of every 20 children with measles gets pneumonia, and about 1 child in every 1,000 who get measles will develop encephalitis. (This is an inflammation of the brain that can lead to convulsions, and can leave the child deaf or mentally retarded.) For every 1,000 children who get measles, 1 or 2 will die from it. Measles also can make a pregnant woman have a miscarriage, give birth prematurely, or have a low-birth-weight baby.
Measles–potential consequences of the anti-vaccine hysteria

One of the memes of the vaccine denialists is that childhood diseases, like measles or whooping cough, are not dangerous. In fact, some parents have set up “pox parties” to deliberately expose their children to these diseases, because anti-vaccine lunatics believe (with all evidence against their beliefs, typical of any science denialist) that natural immunity is better than a vaccine induced immunity.

Already this year, two children have died in the United States as a result of whooping cough. And there’s probably more, because of under-reporting.
