Infectious diseases can develop severe complications or even death, therefore introducing vaccination can be considered one of the most important medical breakthroughs. Immunization programs considerably decreased morbidity and mortality due to infectious diseases, especially in children. Among the diseases that significantly affected the population were included measles, mumps and rubella. Measles is particularly serious because of the complications it can cause both on short and long term. Mumps is severe because it can evolve with meningitis and to measles particular attention should be paid, not only because of its frequent complications, but also because of the manifestations in pregnant women (congenital rubella). Lately, the vaccine coverage has decreased, and in order to remediate this, a very important role is attributed to the health professionals. [ABSTRACT FROM AUTHOR]
