Assessment of the timely administration of the hepatitis B and BCG birth dose and the primary infant vaccination schedule in 2015-2016 in the Mekong Delta, Viet Nam

Although Vietnam started HBV BD vaccination more than 10 years ago, the coverage and timeliness need to improve to reach WHO targets (95% within 24 h after birth). Better training and information of health care workers, and better protocols ensuring timely HBV BD could address these vaccine administration thresholds.
