I'm new here, desperately trying to find opinions. I've had CFS since age 8. (I'm now 30.) And I never had chickenpox as a child. (Neither did my Dad or my grandfather, despite the fact that we were all exposed.) I always assumed that I had some sort of immunity. But now, I'm getting married in a couple months, and as part of the pre-conception workup, I got tested for immunity to many things, including chickenpox. And it came out negative, showing no immunity at all. Puzzling. And now, I don't know what the heck to DO!! My initial CFS crash, at age 8, was preceded by a combined childhood vaccine + flu shot administered together. And a second crash, which left me housebound for 3 years and made me miss 10th-12th grades, was also preceded by a flu shot. (Makes me VERY wary of vaccines, especially live ones.) Anyone know how folks with CFS tend to handle the chickenpox vaccine???
