Subacute sclerosing panencephalitis (SSPE)

[SSPE is touted as a risk factor from measles ('SSPE is a rare complication of measles'--CDC), and to sell MMR, a theory taken apart by Duesberg 1 .  SSPE from vaccination more likely.]

Drug related SSPE

Vaccine related SSPE

Subacute sclerosing panencephalitis (SSPE), a mouthful of a name for such a rare condition, attacks a small number of schoolchildren and teenagers each year, causing dementia, learning disabilities, and finally death. Doctors first recognized SSPE in the 1930s, and by the 1960s the virus hunters were searching for an SSPE germ. At that time, the most fashionable viruses for research belonged to the myxovirus family, which included the viruses that caused influenza, measles, and mumps. Animal virologists therefore started by probing for signs of myxoviruses. Excitement mounted after trace quantities of measles virus were detected in the brains of SSPE patients, and in 1967 most of the victims were found to have antibodies against measles. The facts that SSPE affected only one of every million measles--infected people and that this rare condition appeared from one to ten years after infection by measles were no longer a problem: Researchers simply hypothesized a one- to ten-year latency period. Little wonder they could also easily rationalize that one virus could cause two totally different diseases.
    Koprowski's foray into SSPE research began in the early 1970s. He began isolating the measles virus from dying SSPE victims, a nearly impossible task because their immune systems had long before completely neutralized the virus (some SSPE cases, more-over had never had measles, merely the measles vaccine). His characteristic patience nonetheless paid off, yielding a tiny handful of virus particles from some patients that could be coaxed to begin growing again, if only in laboratory cell culture. In other patients only defective viruses that were unable to grow had remained so many years after the original measles infection. Rather than concluding the measles virus had nothing to do with SSPE, he employed the new logic of virus hunting to argue that a defective measles virus caused SSPE!
    Koprowski continued this line of SSPE research for several more years. But in 1985 Gajdusek himself entered the SSPE fray, publishing a paper with leading AIDS researcher Robert Gallo in which they proposed that HIV, the supposed AIDS virus, caused SSPE while remaining latent. With hardly a blink, several leading virologists jettisoned the old measles-SSPE hypothesis in favor of a newly popular, but equally innocent, virus.
    Multiple sclerosis (MS), the notorious disease that also attacks the nervous system and ultimately kills, has provided yet another opportunity for the virus hunters. First, they blamed the measles virus starting in the 1960s, since many MS patients had antibodies against the virus. Ten years later others suggested the mumps virus, which is similar to measles. The early 1980s brought the coronavirus hypothesis of MS, the category of virus better known for causing some colds. In 1985, with Gajdusek stealing his thunder for SSPE, Koprowski also published a scientific paper that year in Nature with Robert Gallo, in this case arguing that some virus similar to HIV now caused MS. Unfortunately for Koprowski, even this hypothesis was abandoned within just a few years. Slow Viruses: The Original Sin Against the Laws of Virology & Phantom viruses and big bucks By Peter H.
