Are steroids a contraindication to vaccination?
Live virus vaccines such as MMR, OPV, BCG and varicella-zoster vaccines, should not be given to children receiving high dose oral (more than 2 mg/kg/day prednisolone for more than one week) or parenteral (injected) corticosteroid therapy, or extensive topical (skin) steroid therapy for more than 2 weeks. Inactivated vaccines (eg. DTPa-hepB) may be less effective in this group but are not contraindicated. Therapy with inhaled steroids is not a contraindication to vaccination.
