Vaccination coverage for measles, mumps, and rubella in a tertiary hospital of Porto Alegre, state of Rio Grande do Sul

INTRODUCTION: Measles, mumps, and rubella are viral contagious diseases preventable by the MMR vaccine. MMR is a part of the immunization schedule of the Brazilian Ministry of Health, which recommends 2 doses of the vaccine for professionals working in health care facilities. OBJECTIVES: To determine the vaccination coverage for measles, mumps, and rubella among active professionals of a tertiary hospital in the city of Porto Alegre, state of Rio Grande do Sul; to analyze the importance of vaccinating professionals that work at health care facilities; to detect and highlight high-risk services for contagious diseases according to patient profiles - children, pregnant and puerperal women, immunocompromised individuals. METHODS: This is a descriptive transversal study that analyzed the database of the Occupational Medicine Service of Hospital de Clínicas de Porto Alegre considering active professionals in January 2019. RESULTS: We evaluated the vaccination records of 7802 active professionals of this hospital; 52% of them had taken at least 1 dose of the MMR vaccine (1 or 2 doses) and 47% had not been vaccinated. Among high-risk services, 56.4% of the professionals had had at least 1 MMR dose, while 43.4% had not been vaccinated. CONCLUSIONS: This study revealed that the vaccination coverage for measles, mumps, and rubella at the analyzed health care facility was still far from the ideal; however, the Occupational Medicine Service has been making efforts to gradually broaden this coverage.
