Colds after treatment

I’m just wanting to hear if anyone else experiences this after a treatment, surely it can’t just be me.

Throughout the entire lockdowns etc, I worked in an office, took public transport and was responsible for doing the shop for the family and not once did I get sick, not so much as a cold. I was also waiting for my diagnosis for MS.

Since I started my treatment of Tysabri in December 2022, I’ve had covid twice, days after a treatment, and now I have a cold that won’t lift.

Has anyone else found they are more susceptible to getting ill after a treatment?

That has not been my experience (and I’ve been on Tysabri for many years) but I’m not sure that one person’s personal experience is always terribly helpful. The sheer normal randomness of life could comfortably account for your experience as well as for mine!
