Why is MMR contraindicated?

Contraindications for MMR vaccination include history of a severe (anaphylactic) reaction to a previous dose or to any component of the vaccine (such as gelatin or neomycin), pregnancy and immunosuppression.

What is the most common cause of vaccine failure?

There are two main reasons for failure of immunizations: (1) failure of the vaccine delivery system to provide potent vaccines properly to persons in need; and (2) failure of the immune response, whether due to inadequacies of the vaccine or factors inherent in the host.

Why do we vaccinate against rubella?
