Article Synopsis
- Universal immunization has reduced hepatitis B cases, but older adults, especially those over 50, still have a risk for infection, prompting a study in central Brazil to explore the virus’s epidemiology in this age group and assess vaccine effectiveness.* -
- The study involved a clinical trial comparing two vaccine regimens: a higher dose regimen (40 μg) and a standard dose regimen (20 μg), both administered in three doses over six months to individuals lacking vaccination documentation.* -
- Results showed a 16.6% exposure rate to HBV, with the higher dose regimen producing significantly better protective titers and higher levels of immune response, suggesting the need for reinforced vaccination for older adults.*
Background: In recent decades the epidemic of asymptomatic sexually transmitted infections has extended deep into Brazil, including small towns and rural areas. The purpose of this study was to investigate the epidemiology of HIV, syphilis, and hepatitis B (HBV) and hepatitis C viruses (HCV), and to evaluate immunization coverage against hepatitis B in a group of rural workers in Brazil.
Methods: In 2016, a cross-sectional study was conducted with 937 manual sugarcane cutters of the Midwest and Northeast Regions of Brazil.

We used a cross-sectional study in 2011 to estimate prevalence and risk behaviors for self-reported symptomatic sexually transmitted infections (STI) in rural settlers in Midwestern Brazil. There were 353 individuals recruited who had been living in the settlement for more than 6 months. The endpoint variable was having reported vaginal discharge, urethral discharge, genital ulcers, or anogenital warts in the previous 12 months.
