What are the contraindications and precautions for MenB?

As with all vaccines, a severe allergic reaction (for example, anaphylaxis) to a vaccine component or to a prior dose is a contraindication to further doses of that vaccine. The tip caps of the Bexsero pre-filled syringes contain natural rubber latex which may cause allergic reactions in latex sensitive individuals. A moderate or severe acute illness is a precaution; vaccination should be deferred until the person’s condition has improved. Because MenB is an inactivated vaccine it can be administered to persons who are immunosuppressed as a result of disease or medications; however, response to the vaccine might be less than optimal. Data on MenB vaccination during pregnancy is limited. Pregnancy a precaution to MenB vaccination, but MenB may be administered if, in the judgment of the clinician, the benefits outweigh any potential risks.
