Pea, sorry but that's incorrect. You can have a flu shot on a biologic. You cannot have any innoculation that involves a
live vaccine (such as for yellow fever; although they will consider the rubella vaccine in women of child-bearing years); however, the flu shot is safe for us.
So, unless your doctors have told you it is unsafe for you specifically, if you are on a biologic medication, please do get a flu shot!!
Just wanted to set the record straight.

Love and Warm Hugs,
