When that happens, it's most likely because that person has a weak immune system, correct? So what evidence do we have to say that person wouldn't have died from the next disease to come along (e.g. diarrhoea or simply catching a cold and dying from pneumonia?).

Just a question... kind of playing the devil's advocate, but I think it's usually ignored by most people when talking about vaccination.

Subacute sclerosing panencephalitis (SSPE) isn't due to an immunocompromised state. That happens in normal people who get measles. It's rare in adults that contract measles, but much more common in kids that get it.

A similar disease called progressive multifocal leukoencephalopathy (PML) is due to an immunocompromised state. Patients with HIV and those taking certain medications with multiple sclerosis are at risk.
