Resumo(s)
A measles, mumps, and rubella (MMR) trivalent vaccine was added to Portugal’s National Immunisation Programme (NIP) in 1987. All vaccines are given at health centres, free of charge, but an epidemic of mumps began in 1995, firstly in northern Portugal and has now spread to other areas. Initially, only one dose of MMR vaccine at the age of 15 months was recommended. In 1990 a second dose at the age of 11 to 13 years was added. Portugal was one of the first countries in Europe to advocate this policy.
