ABSTRACT
BACKGROUND:
Brazil conducted mass rubella vaccination campaigns to meet disease elimination goals by 2010. An analysis of rubella vaccination opportunities was conducted to target population groups with concentrations of unvaccinated individuals.METHODS:
Rubella vaccination strategies for all 27 states were reviewed between 1992 and 2006. Yearly vaccination coverage was calculated by dividing number of doses of measles-rubella or measles-mumps-rubella vaccines administered by census estimates of target populations. For annual birth cohorts (1967-2005), percentages of persons not vaccinated prior to 2007 were estimated by subtracting the highest coverage obtained in any vaccination strategy (routine or campaign) from 100%. Cohort analysis results were compared with rubella incidence by population group.RESULTS:
An estimated 28.9 million males and 7.7 million females aged 2-40 years in 2007 remained unvaccinated against rubella, corresponding to 43.0% of males and 11.5% of females of these ages in Brazil. The highest percentages of unvaccinated birth cohorts (93.6%-98.1%) were identified among males aged 26-40 years. In rubella outbreaks reported during 2007, the highest disease incidence (22 cases per 100000 population) occurred among males aged 20-29 years.CONCLUSIONS:
Analysis of rubella vaccination opportunities identified concentrations of unvaccinated adults and adolescents for targeting mass vaccination to eliminate rubella and congenital rubella syndrome in Brazil.
