My opinion is that your pharmacist messed up badly, by recommending the vaccine - and please forgive my ignorance if the new inactivated
vaccine for
shingles(not live) has been already developed
and used in your case , which most likely would not have worked anyway, because of your Humira and Prednisone treatment.
If I were you I would probably seek a holistic or naturopathic doctor, to help me correct some of this and bring me back to at least the pre-vaccination state.
