This table summarizes outcome data on infants born to persons with hepatitis B virus infection from the CDC Perinatal Hepatitis B Prevention Program (PHBPP). The 2020 birth cohort includes infants born in 2020 and followed through December 31, 2021.
Among the 7,649 infants whose care was managed by the PHBPP, 95% received recommended prophylaxis at birth, 86% completed the vaccine series (regardless of prophylaxis), and 65% received recommended post-vaccination serologic testing.
Among infants who received post-vaccination testing (4,975), there were 20 (0.4%) cases of perinatal hepatitis B transmission.
