I thought the rebound was pretty much understood.

Natalizumab is an approved medication for highly active multiple sclerosis (MS). Progressive multifocal leukoencephalopathy (PML) may occur as a severe side effect of this drug. Here, we describe pathological and radiological characteristics of immune reconstitution inflammatory syndrome (IRIS), which occurs in natalizumab-associated PML after the cessation of therapy, and we differentiate it from ongoing PML.

Kind of places the potential Tysabri user in a difficult position....use the drug for more than 2 years and see the risk of PML climb higher and higher. Stop using the drug to reduce the PML risk and experience a bad rebound effect!! All this and paying over $ 60,000 a year!
