What does Plegridy to our immunity system? What cells are "modified" by it? I take it for 3 years and a half and always forget to ask my neuro about this. I know it supresses something in our immunity but what thing is that? I always hated to take medicines, but this time I obviously had to. It's ok... I have one day of flu like symptoms and that's all. No more relapses (I had only 3 in 20 years anyway and totally recovered). Really would like to know what this thing does. I can't find an article about that. Can you help me? Thank you so much for any information. All the best for all of you and happy 2021!
