Chronic hepatitis B virus (HBV) infection occurs in 90% of infants infected perinatally but is prevented when a hepatitis B vaccine is given within 24h of birth (HepB-BD), followed by 2–3 additional doses.Using Spearman’s rho correlation coefficients (rho), we analyzed global and regional data to assess correlations between HepB-BD coverage, institutional delivery rates (IDR), skilled birth attendance...
Hepatitis B vaccine birth dose (HepB-BD) was introduced in Lao People’s Democratic Republic to prevent perinatal hepatitis B virus transmission in 2008; high coverage is challenging since only 38% of births occur in a health facility. Healthcare workers report being unaware of home births and thus unable to conduct timely postnatal care (PNC) home visits. A quasi-experimental pilot study was conducted...
Hepatitis B virus (HBV) is highly endemic in many of the Pacific Island countries. Four island countries—Cook Islands, Kiribati, Niue, and Tokelau—sought to evaluate the success of their hepatitis B vaccination programs by conducting nationally representative serosurveys among children born post-vaccine introduction.Cook Islands, Niue, and Tokelau conducted school-based census serosurveys because...
Hepatitis B vaccine birth dose (HepB-BD) was introduced in Lao People's Democratic Republic (Lao-PDR) to prevent perinatal hepatitis B virus transmission. HepB-BD, which is labeled for storage between 2 and 8°C, is not available at all health facilities, because of some lack of functional cold chain; however, previous studies show that HepB-BD is stable if stored outside the cold chain (OCC). A pilot...
In the pre-vaccination era, the prevalence of chronic hepatitis B virus (HBV) infection in the World Health Organization (WHO) Eastern Mediterranean Region (EMR) ranged from two to seven percent in a total population of over 580 million people. Mortality estimates place cirrhosis among the top ten causes of years of life lost in the EMR. The region has made notable achievements, improving coverage...
Hepatitis B vaccination in the Philippines was introduced in 1992 to reduce the high burden of chronic hepatitis B virus (HBV) infection in the population; in 2007, a birth dose (HepB-BD) was introduced to decrease perinatal HBV transmission. Timely HepB-BD coverage, defined as doses given within 24h of birth, was 40% nationally in 2011. A first step in improving timely HepB-BD coverage is to ensure...
Hepatitis B virus (HBV) is highly endemic in Cambodia with an estimated pre-vaccine hepatitis B surface antigen (HBsAg) prevalence of 9%. By 2005, a hepatitis B vaccination program was implemented to decrease infection rates in children. We conducted a serosurvey to evaluate the impact of the vaccination program in 2011.A cross-sectional two-stage cluster survey was conducted to estimate HBsAg prevalence...
