ABSTRACT

Brazil was one of the first countries in Latin America to introduce free and universal vaccination against hepatitis B, but reaching vulnerable groups is a challenge. This study investigates the immunization situation against hepatitis B and associated factors in 353 homeless individuals from Central Brazil, between August 2014 and June 2015. Although the Brazilian public health provides universal vaccination against hepatitis B, and a low immunization rate (19.4%) was observed in homeless people. Only age was associated with seroprotection against hepatitis B (p = .03). Vaccination strategies should be strengthened, whether in shelters or on the streets directly.

摘要

巴西是拉丁美洲第一个对乙型肝炎实行免费和普遍疫苗接种的国家之一，但要达到弱势群体的目标是一个挑战。这项研究调查了2014年8月至2015年6月之间来自巴西中部的353名无家可归者的乙型肝炎及相关因素的免疫状况。尽管巴西公共卫生部门提供了针对乙型肝炎的通用疫苗接种，但免疫率较低（19.4％）在无家可归的人中。只有年龄与抗乙型肝炎的血清保护有关（p = .03）。无论是在庇护所还是直接在街头，都应加强疫苗接种策略。
