Humira follow Tanlou's experience here.

Im just going to do whatever im told - if I feel rough over the next few days I will blame the flu and pneumonia jabs - I have felt ok since taking the HUMIRA jabs on Thursday

Yes it's best to do what they say, they have their reasons and they know more about your health than I do. Some people are more vulnerable to virus, infections, etc so they could be just taking the belt and braces approach.

If you've had no problems with the Humira shots giving you a flu or cold symptoms, then like you say you will be able to blame the others.

Tanlou you still have Fumaderm as your treatment in your profile.

@Kat You are right the Bio treatments do lower your immune system, so yes you have to be little bit more careful. Having said that I'm a believer of letting my body fight the flu by itself, but like I said above some are more vulnerable than others.
