The modern treatments are much more effective than anybody had expected, Ocrecus went from something used in the last resort to standard care in less than a decade. I have no issue with it whatsoever though that’s not the case for everyone, and it’s now available as a 6 month injection rather than a 8+ hour infusion thankfully. The older drugs were unbelievably bad (blindness, infection, you name it), but Ocrecus has been very tame in comparison. Can’t get vaccinated for Measles (and have 0 immunity) but that’s my only limitation really.
