Article Synopsis
- A study in Brazil shows that, while hepatitis A virus (HAV) infection rates have decreased overall, children with low socioeconomic status living in urban peripheries remain highly susceptible to infection, particularly those under five years old (up to 90%).
- The research found that anti-HAV antibody prevalence increased with age, reaching over 50% in children aged 10-14, suggesting areas with intermediate levels of HAV endemicity among disadvantaged populations.
- Current hepatitis A vaccinations in Brazil are limited to high-risk groups or private clinics, making them inaccessible to low SES individuals; thus, the study advocates for the inclusion of the hepatitis A vaccine in the Brazilian National Immunization Program.
