"For patients having a Multiple Sclerosis relapse, vaccination should be delayed until the relapse is no longer active"

I'm not a medical doctor so I don't know whether suggestions like this are common for other illnesses. It seems plausible to me on a superficial level that possibly people with ME/CFS should avoid vaccinations during relapses. Like many things, it would be great to have more research done on such topics.

I was vaccinated (tetanus, rubella, x2 Hep B) for a course I was taking just one month after sudden viral onset

It was after the second Hep B shot that my energy/stamina and head in a fish bowl sensation began.

 

Little risk of that, as unimportant things like seeing a doctor are put off until the relapse is over.
