Here is something interesting from Roald Dahl who is the author of Charlie and the Chocolate Factory and the death of his daugter from measles:
"Olivia, my eldest daughter, caught measles when she was seven years old. As the illness took its usual course I can remember reading to her often in bed and not feeling particularly alarmed about it. Then one morning, when she was well on the road to recovery, I was sitting on her bed showing her how to fashion little animals out of coloured pipe-cleaners, and when it came to her turn to make one herself, I noticed that her fingers and her mind were not working together and she couldn’t do anything.
“Are you feeling all right?” I asked her.
“I feel all sleepy, ” she said.
In an hour, she was unconscious. In twelve hours she was dead.
The measles had turned into a terrible thing called measles encephalitis and there was nothing the doctors could do to save her.
It is not yet generally accepted that measles can be a dangerous illness.
Believe me, it is. In my opinion parents who now refuse to have their children immunised are putting the lives of those children at risk.
In America, where measles immunisation is compulsory, measles like smallpox, has been virtually wiped out.
Here in Britain, because so many parents refuse, either out of obstinacy or ignorance or fear, to allow their children to be immunised, we still have a hundred thousand cases of measles every year. [Since this was written in 1986, the success of the MMR vaccination has reduced this figure to several thousand each year, but unvaccinated children are still at risk, and some do still die of measles].
Out of those, more than 10,000 will suffer side effects of one kind or another.
At least 10,000 will develop ear or chest infections.
About 20 will die.
LET THAT SINK IN.
Every year around 20 children will die in Britain from measles.
So what about the risks that your children will run from being immunised?
They are almost non-existent. Listen to this. In a district of around 300,000 people, there will be only one child every 250 years who will develop serious side effects from measles immunisation! That is about a million to one chance. I should think there would be more chance of your child choking to death on a chocolate bar than of becoming seriously ill from a measles immunisation."
