Measles wipes immune system memory making victims susceptible to secondary infections which then kill them because their immune system is incompetent.
People need to stop pretending that it’s just a simple childhood disease and not dangerous.
I think that is one of the biggest problems - people don't see it as being as dangerous as it is. 1-3/1,000 is terrible odds to not be concerned. That is the death rate from measles complications today.
I remember having the measles at 6 years of age - yes, the dark room, no television watching, high fever, mandatory 2 weeks quarantine from school. I was thrilled that with a simple vaccine my children would not have to be subjected to that disease (mumps too).
