Status of hepatitis B birth dose vaccination coverage in Vietnam during 2020 - 2022

A descriptive cross-sectional study in 63 provinces/cities in Vietnam during 2020 - 2022 was conducted to describe the current status of hepatitis B birth dose vaccination in Vietnam. The results showed that the proportion of hepatitis B birth dose (HepB-BD) vaccination in this period was 83.2%, of which the proportion of HepB-BD vaccination within 24 hours and after 24 hours of birth was 78.9% and 4.3% respectively. For socio-economic regions, the highest proportion of HepB-BD vaccination was 90.9% in the Red River Delta and the lowest was 72.3% in the Central Highlands. The proportion of HepB-BD vaccination within 24 hours was less than 70.0% in Central Highlands during 2020 - 2022. The proportion of HepB-BD vaccination in Vietnam in the period 2020 - 2022 was high, with uneven changes between years and socio-economic regions. It is necessary to increase the proportion of HepB-BD vaccination, especially within 24 hours after birth.
