Survey of rubella knowledge and acceptability of rubella vaccination among Brazilian adults prior to mass vaccination.

OBJECTIVE Evaluate knowledge of rubella and acceptability of vaccination and identify sources of health information among brazilian adults to inform communication strategies for a national vaccination campaign to eliminate rubella and congenital rubella syndrome (CRS). METHODS From 5-8 July 2008 a qualitative telephone survey was conducted among a nonprobabilistic sample of brazilian adults 18 to 65 years of age (n = 1 023) from all five geographic regions of Brazil to measure knowledge of rubella and willingness to receive the vaccine and to identify sources of health information. Frequencies of responses were stratified by respondents' sex, age, education, and income. RESULTS Although 69.9% of respondents said they knew what rubella was, actual knowledge of the disease was limited, with only 29.9% answering affirmatively when asked if they would recognize symptoms of rubella infection. Self-reported knowledge increased with increasing age, education, and income, and was higher among women than men. A total of 94.5% of the respondents expressed willingness to be vaccinated for rubella elimination. The most frequently mentioned sources of health information were television and doctors. CONCLUSIONS Despite limited knowledge of rubella, brazilian adults expressed willingness to be vaccinated for disease elimination.
