Ever since the introduction of the<unk>  vaccine, there has been a marked reduction of the incidence of this disease in the population. The widespread use of<unk>  vaccine has led to a greater than 99% reduction in<unk>  cases in the United States, when compared with the non vaccine era. Therefore the most effective way of preventing<unk>  is with active immunization provided by this vaccine, which is often incorporated with the rubella and/or mumps vaccines, in the MMR vaccine, in countries where these illnesses represent a problem. Unfortunately,<unk>  is still a common disease in developing countries, where the virus is highly contagious and is able to spread across large areas, where vaccination is not common.
