It is considered an overactive immune system, but that doesn't mean effective immune system. Basically it's so busy trying to find things to attack that it completely ignores the enemy walking through the front gate. Still for most I would say it's a matter of personal preference as to get or not looking at who you're around and where you go.

I haven't gotten my shot pretty much since I'm largely at home. I do go out to the store and things from the store are brought home, my husband deals with the public at large too, but my exposure now is far more limited than when I was attending classes and working.

If you're the type to catch anything and everything going around....get the shot if you're going around....not so much...ehhh....up to you. You cannot catch the flu from the shots, though the nasal spray one is live but not a "shot". And yes you can, like any other medication, food group, or environmental factor, have an allergic reaction, serious side effect, or injection infection and so forth arising from it. Though the biggest one is knowing if you have a sensitivity to eggs let the pharmacist/doctor know so they can give you the non-egg one.

The sensitivity to eggs doesn't even have to be some crazy allergy where you need an epipen to eat a brownie, it could be as simple as eating 2 eggs with toast in the morning rather than just 1 makes you a little queasy, or soft boiled egg doesn't seem to sit as well as a hard boiled one. That same sensitivity can equal flu-like symptoms from the shot as well as pain, swelling, redness etc....

Steriods also shouldn't preclude you from getting the shot, only the nasal spray which MS already nixed. If anything that's more the double whammy putting you towards the top of the list for those that need to get it. Though you do have youth on your side a bit to where I wouldn't expect any doctor to twist your arm over getting one. 10-12 yrs from now.... But then you're reaching an age where other shots start, pneumonia...shingles...
