1. Background  
 
Introduction  
Hepatitis B virus (HBV) infection can be transmitted from mother -to-child during pregnancy and delivery. 
Without any interventions, up to 85% of infants born to women with HBV infection acquire HBV 
infection. Perinatal ly acquired  HBV infection has severe health and economic consequences : about 90% 
of infants perinatally infected with HBV will develop chronic hepatitis B, and 25% of people infected with 
HBV during childhood will die prematurely due to HBV-related complications  including liver cirrhosis and 
liver cancer . (1, 2)  
 
Up to 2.4 million people in the United States are estimated to have hepatitis B; about half of people with 
hepatitis B in the U.S. are  unaware of their infection. About 75% of people with chronic hepatitis B in the 
United States  were born in counties with intermediate and high prevalence of hepatitis B  and 
predominantly were infected at birth  or during early childhood . In the United States, decades of evolving 
hepatitis B vaccination recommendations  among infants and children have shifted the epidemiology of 
acute hepatitis B cases from children to unvaccinated adults . In 2023, 14,400 acute hepatitis B cases 
were estimated to occur in the U.S., with the highest rates among adults aged 40 -59 years; among 
reported cases of acute hepatitis B, only 26% reported an associated risk behavior, with 28% reporting 
no risk, and 4 6% missing data on risk factors. Unlike children, adults who acquire new HBV infection have 
higher viral clearance rates  and lower risk for developing chronic infection. (3-9) 
 
Hepatitis B vaccination is the cornerstone of hepatitis B prevention and control.  The hepatitis B vaccine is 
the first anti -cancer vaccine and has been available in the United States for more than 40 years. Two 
types of products are available for prophylaxis against  perinatal  HBV infection: hepatitis B vaccine, which 
provides long -term protection against HBV infection and is recommended for both preexposure and  
postexposure prophylaxis; and hepatitis B immune globulin (HBIG), which provides temporary protection 
and is indicated only in certain postexposure settings.  Two single -antigen h epatitis B recombinant 
vaccines are FDA -approved for the vaccination of persons starting at birth in the U.S.: Recombivax HB, 
approved in  1986 and Engerix -B, approved in 1989 . Hepatitis B vaccination is a multi dose series , typically 
consisting of 3 doses, with increasing s eroprotection after each dose. Three doses of hepatitis B are 
needed to ensure full protection  where 95% of healthy infants develop  a protective antibody response 
2 
 (anti -HBs ≥ 10  mIU/ mL). When administered shortly after birth  to infants born to HBsAg -positive women , 
hepatitis B vaccination and HBIG reduce mother -to-child transmission by 94%. (1, 10 -13) 
 
Prevention of perinatal or early life HBV infection underpins the recommendation  for hepatitis B 
vaccination starting at birth.  Since 1988, u niversal hepatitis B screening (with HBsAg) has been 
recommended for all pregnant women in the first trimester of pregnancy , as has testing later in 
pregnancy for women with risk behaviors  and testing at delivery for women whose hepatitis B status is 
unknown. Hepatitis B vaccination has been recommended  at birth for all infants born to women known 
to have HBV infection since 198 4 (specified to within 12 hours of birth in 1988),  and among all infants 
born to women with unknown hepatitis B status since 1991.  Hepatitis B immune globulin has been 
recommended to be administered  within 12 hours of  birth for all infants born to women known to have 
HBV infection since 198 4, and among infants born to women with unknown hepatitis B status since 
2018.  In 1991, the US adopted a strategy for u niversal h epatitis B vaccination  of all  infants . Beginning in 
2005, the first dose of hepatitis B vaccine among infants born to HBsAg -negative women was 
recommended to be administered at the birth hospital ; this was updated in 2018 to specify within 24 
hours of birth . (1, 14 -20) 
 
In the context of these evolving hepatitis B vaccination recommendations among newborns and children, 
the number of reported US cases of acute hepatitis B has dropped 88% from 1991 (18,003 cases) to 2023 
(2,214 cases). The United States’ comprehensive strategy to prevent  hepatitis B is based on : 1) routine 
testing of all pregnant women for HBsAg ; 2) post exposure  prophylaxis within 12 hours of birth with 
hepatitis B vaccine and HBIG of all infants born to women who are HBsAg -positive or HBsAg -status 
unknown ; 3) universal vaccination of all infants beginning at birth; 4) routine vaccination of previously 
unvaccinated children, adolescents, and adults aged 19 -59 years ; and 5) vaccination of all adults at risk 
for HBV infection or who request vaccination . (1, 9, 20, 21)  
 
Transmission , Natural History of Disease , and Associated Healthcare Costs  
HBV transmission occurs through percutaneous or mucosal exposure to infectious blood or body fluids . 
The virus  can remain viable for over 7 days on environmental surfaces at room temperature. The two 
primary sources of HBV infection among children are perinatal transmission from mothers with hepatitis 
B and horizontal transmission from infected household contacts.  Prior to the widespread availability of 
postexposure prophylaxis  (i.e., vaccine and HBIG  within 12 hours of birth ), the proportion of infants born 
to HBsAg -positive women who acquir ed HBV infection was as high as 85%. Children living with a person 
with chronic HBV infection in a household or community setting are also at risk and transmission rates 
have ranged to up to 11% in US settings. (1, 22 -24) 
 
Young children with acute hepatitis B rarely have symptoms, but 90% of infants who are infected with 
HBV become chronically infected . In contrast, among persons 5 years of age and older , fewer t han 5%  
develop chronic infection . Since the risk of chronic infection increases with decreasing age, people who 
are infected in early childhood experience a disproportionately higher burden of disease attributable to 
chronic HBV infection. About 25% of individuals chronically infected during childhood will develop end 
3 
 stage liver disease or liver cancer and die prematurely.  Fulminant hepatitis occurs in ≤1% of acute 
infections, but the incidence of fulminant hepatitis B is higher in infancy than in other pediatric age 
groups . (1, 8, 21, 25 -28) 
 
Chronic HBV infection  can progress to cirrhosis, hepatocellular carcinoma (HCC), liver transplant, and 
death. Based on US cancer data from the Surveillance, Epidemiology and End Results (SEER) Program, 
over 38,000 HCC cases were forecasted for 2020 and over 56,000 HCC cases we re forecasted for 2030. 
HBV is an important cause of HCC, with 10% to 15% of patients with HCC attributed to HBV  infection . The 
burden of US hepatitis B related hospitalizations is significant; each year, more than $1 billion is spent on 
hepatitis B -relate d hospitalizations, not including indirect costs such as poor quality of life, reduced 
economic productivity, long -term disability, and premature death. The estimated annual costs of treating 
one patient with hepatitis B in the United States, adjusted for inflation are up to $93,935 for those with 
less severe disease and up to $324,849 for those requiring liver transplant.  (2, 29 -33) 
 
Hepatitis B is Vaccine Preventable with Robust Seroprotection  
Hepatitis B vaccination is the most effective measure to prevent HBV infection and its consequences . The 
plasma -derived hepatitis B vaccine was licensed in 1981; recombinant hepatitis B vaccines replaced the 
plasma -derived vaccines in the U.S. by the late 1980’s.  Hepatitis B  recombinant vaccines  are available as 
a single -antigen formulation and in combination with other vaccines. Two single -antigen vaccines 
recommended for use in the United States, Engerix -B and Recombivax HB, are used for the vaccination of 
persons starting at birth. An extensive  body of literature resulting from over more than 40 years of use  in 
the United States and other countr ies demonstrates that the hepatitis B vaccines are safe and effective in 
protecting infants from hepatitis B.  (1) 
 
The efficacy of the hepatitis B  vaccine alone in preventing perinatal transmission is ~75%. Hepatitis B 
immunoglobulin provides passively acquired anti -HBs and temporary protection (i.e., 3 –6 months) and is 
generally used as an adjunct to hepatitis B vaccine in infants born to HBsAg -positive mothers and in 
certain other postexposure prophylaxis situations. The efficacy of HBIG alone is around 71%. When 
combined with the hepatitis B  vaccine, the efficacy of HBIG and hepatitis B birth dose (HepB -BD) vaccine 
is 94%. The sooner the HepB -BD vaccine is provided after birth, the greater its effectiveness in 
preventing perinatal transmission. The optimal recommended timing is to provide the vaccine within 24 
hours of birth , accelerated to  within 12 hours if the maternal HBsAg status is p ositive or unknown.  
Unvaccinated infants remain at risk of non -perinatal HBV acquisition  through exposure to a  person with 
HBV infection in a household or community  setting .  HepB -BD provides protection for infants at risk from 
household exposure after the perinatal period. (1, 23, 24, 34, 35)  
 
Among health y infants, 25% and 63% achieve protective hepatitis B surface antibody levels after the first 
and second dose, respectively , however full protection is only achieved with the complete vaccine series .  
The 3 -dose hepatitis B  vaccine series produces a protective antibody response in 98% of healthy term 
infants, and 95% of healthy infants overall. Seroprotection from vaccination lasts for decades. In one 
4 
 Alaska -based study, over 90% of primary responders were estimated to have protective immunity for 
more than 30 years after vaccination. (1, 11, 13, 28, 36 -40)  
 
Hepatitis B Birth Dose Provides a Critical Safety Net in the Preve ntion of Perinatal and Early Childhood 
Transmission  
Universal  HepB -BD provides a critical safety net for infants who may have unrecognized exposure(s) to 
HBV infection during pregnancy or early childhood  due to a multitude of reasons  resulting in gaps in 
protection against perinatal infection.  Reasons for missed opportunities to prevent perinatal 
transmission include lack of prenatal care,  where overall 15% of pregnancies receive inadequate or no 
prenatal care  (where inadequate care is defined a s care after the 4th month of pregnancy and includes 
less than 50% of visits) . Additionally , missed opportunities arise from  gaps in maternal screening 
implementation, incorrect screening tests performed, errors in interpreting the screening test or the 
transcription of the screening test , lapses in providing standard of care post exposure prophylaxis , and 
acute /window period infection . Gaps in perinatal HBV testing during  pregnancy indicate 12 -16% of 
pregnant women in the United States  had no record of being test ed for HBsAg, with lower testing rates 
among Medi caid-enrolled women. Further, d espite a robust national perinatal hepatitis B prevention 
program, the program identifies less than one -half of infants estimated to be born to HBsAg -positive 
women each year, highlighting a critical gap in identifying perinatally  exposed infants . Case reports of  the 
medical  outcomes  for perinatally exposed infants demonstrate the catastrophic impact when universal 
HepB -BD is not fully implemented. (41-47) 
 
Infants who receive HepB -BD are more likely to complete their vaccination series and had a positive 
impact on rates of being up to date for other age -appropriate vaccines . Additionally, there is a risk for 
horizontal transmission in the household from persons who are not aware of their infection status; 50% 
of people in the US are unaware of their infection.  Universal HepB -BD is of critical importance and 
provides a safety net for infants who may have unrecognized exposure(s) to HBV infection during 
pregnancy or early childhood. (1, 3, 19, 25, 48, 49)  
 
 
2. Epidemiology  
Shifting Epidemiology of Acute Hepatitis B in the U.S.  Reflects Success of Hepatitis B Vaccination 
among Newborns and Infants  
Three decades  of evolving  hepatitis B vaccination recommendations among newborns and infants ha ve 
paralleled marked  reductions in acute hepatitis B cases in the United States. Following the introduction 
of recommendations for all infants born to HBsAg+ women to receive hepatitis B vaccination and HBIG 
within 12 hours of birth, the reported number of acute hepatitis B cases in the U.S. fell by 22% from 
23,177 in 1988 to 18,003 in 1991. Following the 1991 recommendations which included  provid ing 
hepatitis B vaccination within 12 hours of birth for infants born to women with unknown HBsAg status as 
well as introducing universal hepatitis B vaccination for all infants, reported number of acute hepatitis B 
cases dropped another 69% from 1991 to 2005 ( 5,494 ). Finally, following the 2005 recommendation 
specifying that  the first dose of infant hepatitis B vaccination occur prior to hospital discharge  and the 
5 
 further specification that the dose occur within the first 24 hours of life , the reported number  of acute 
hepatitis B  cases  fell an additional 60% from 2005 to 20 23 (2,214 ).  
Figure 1  
 
 
From 1991 through 2023, rates of reported cases of acute hepatitis B have decreased among all age 
groups, with the lowest rates among persons <19 years of age and those aged 20 -29 years, indicating a 
generational impact of more than 3 decades of evolving h epatitis B vaccination recommendations 
among newborns and infants. (9, 17, 19, 21, 25, 50)

3. Updated Rapid Systematic Review for studies on hepatitis B birth dose vaccine within 24 hours of 
birth  
In response to the request from the ACIP Chair to provide “ results from randomized trials concerning the 
administration of the HepB vaccine within 24 hours of birth, with all results stratified by the HepB 
infection status of the mother. Include both efficacy data and adverse events, including all -cause 
morbidity a nd mortality. For children whose mothers are HepB negative, present results for all children 
combined as well as stratified by pre -mature birth and birth weight. If randomized data is lacking for any 
of the requested populations, please mention that ”, an updated rapid systematic review (URSR) for 
studies on hepatitis B birth dose (HepB -BD) vaccination within 24 hours of birth was conducted spanning 
12/17/2011 – 8/14/2025,  building on an existing systematic review  (ESR)  (28) spanning 1/1/1987 – 
12/16/2011.  
The inclusion criteria  for the review included studies for  newborn infants receiving a  monovalent  
hepatitis B vaccine within 24 hours of birth  for a list  of outcomes ( seroprotection , efficacy,  safety , 
morbidity and mortality). The definitions and timepoints for seroprotection, efficacy, and safety 
outcomes are as follows: s eroprotection is defined as  anti -HBs ≥10 mIU/mL mL at least 1 -2 month s after 
the final dose in the vaccine series or between 9 -12 months of age and is the first time point reported 
immediately following the last dose in a vaccine series; efficacy is defined as HBsAg and/or HBV DNA 
positivity at the latest available timepoint ; safety is reported by local and systemic adverse events and is 
reported at birth or the closest time point immediately after the birth dose.  Morbidity is defined as 
severe illness or hospitalization and mortality is defined as death.  

7 
 The ESR search (n=833) and the URSR (n=1380) were further assessed using the inclusion criteria 
focused on the ACIP request. Seventeen studies met the inclusion criteria  (7 from the ESR and 10 from 
the URSR). The 17 studies were grouped by efficacy trials,  timing of the vaccination, product or 
formulation differences , dose and schedule , and HBIG co -intervention for the specified outcomes of 
interest (seroprotection, efficacy and safety outcomes). The two HBIG co -intervention trials were 
reviewed but not inc luded in the briefing document since these  studies did not address the question .  
Other intervention characteristics included the vaccine type administered (Engerix, Recombivax or other 
hep B vaccines), dose and schedule.  
Across intervention study types (timing of vaccination (birth vs 18 months); efficacy trials; product and 
formulation; dose of vaccine and schedule) meeting the rapid systematic review inclusion criteria  can be 
summarized as:  
• Hepatitis B vaccine series first administered at birth achieved high levels of seroprotection in 
infants born to HBsAg -positive women  and HBsAg -negative women;  
• Among infants born to HBsAg -positive mothers, hepatitis B birth dose vaccin ation demonstrated 
efficacy in the prevention of perinatal transmission ;  
• Hepatitis B birth dose  vaccine  is safe and resulted in few local and systemic adverse effects, 
including infants born to HBsAg -negative mothers ; and  
• Head -to-head comparisons of various hepatitis B recombinant vaccine products, doses, and 
schedule show ed no meaningful differences in reported outcomes . 
The URSR did not identify placebo -controlled trials assessing efficacy; given that the efficacy of the HepB 
vaccine was established in the 1980s and 1990s , this is unsurprising as  it is unethical to withhold a 
proven, safe and effective intervention simply to include a placebo group . There were  also limited 
reporting outcomes for preterm, low birth weight and extremely low birthweight infants, as well as for 
morbidity and mortality. Bias was assessed using the Cochrane Risk of Bias, version 2 (RoB 2) (51). This 
tool assesses  risk of bias in RCTs related to  the following domains : randomization process, deviation from 
intended intervention, missing outcome data, measurement of outcome and selection of reported 
results . Of note, many of the studies were done before the wide application of the CONSORT statement  
(52), which seeks to improve reporting of randomized controlled trials (RCTs)  Most of the RCTs (59%) 
assessed had a high risk of overall bias primarily due to the  domains of randomization and measurement 
of outcomes . In summary, the body of evidence from the ESR and the URSR support the findings that:  
• Hepatitis B birth dose induces high seroprotection and efficacy ; 
• Hepatitis B birth dose vaccine is safe ; and  
• Head -to-head comparisons of various hepatitis B recombinant vaccine products, doses, and 
schedule show no meaningful differences  in reported outcomes in efficacy and safety .

 Appendix 2  
Global hepatitis B v accination policies and prevalence in pregnant women  
Global Hepatitis B Birth Dose Vaccination Policies  
In 1987, the WHO Hepatitis and Immunization Technical Advisory group s emphasized the importance of 
hepatitis B vaccination to control infections globally  and recommended hepatitis B vaccination in infancy 
focusing on countries where HBsAg prevalence was higher than 2% . In 2004, the WHO recommended 
hepatitis B birth dose vaccination as soon as possible after birth (within 24 hours) focusing on countries 
with intermediate and high endemicity (HBsAg  prevalence >2%) while also recommending hepatitis B 
vaccination  in low endemicity settings especially to infants born to HBsAg positive mothers. In 2009 and 
then in 2017, the WHO Strategic Advisory Group of Experts reevaluated  the data and base d on evidence 
to recommendations analysis, recommended universal hepatitis B birth dose vaccination as soon as 
possible after birth, preferably within 24 hours of birth , followed by completion of 3 or 4 dose hepatitis B 
vaccination series  among all infants  in all countries irrespective of HBsAg prevalence . Those vaccination 
recommendations  have evolved based on global goals which focused in the 1990s and early 2000s on 
controlling  hepatitis B through scale up of childhood immunization and then progressed  in 2015 to focus 
on eliminating viral hepatitis as a public health threat  by 2030 through the scale up of prevention, 
screening and treatment . The United States has endorsed the global goals of elimination of viral hepatitis  
by 2030  and developed national strategies to achieve the targets .  
Globally , of the 194 WHO  member states, 116 countries recommend universal hepatitis B birth dose 
vaccination to all newborns , in alignment with global recommendations. Relatively f ew countries (3 3) 
provide selective hepatitis B birth dose to infants born to mothers who are either HBsAg -positive o r of 
HBsAg -unknown status . Two countries have partially introduced universal HepB -BD. In Canada , New 
Brunswick, the Northwest territories and Nunavut provide universal HepB -BD while other provinces 
provide selective HepB -BD. Pakistan introduced universal HepB -BD in two of its most populated 
provinces (Punjab and Sindh).   
The 43 c ountries that have not introduced HepB -BD are mostl y countries  in Sub -Saharan Africa , but this 
is changing and in 2024, many countries  have either initiated introduc tion this year  or expressed interest 
in introducing HepB-BD in their immunization schedule  in the next 3 -5 years .

Partially  introduced universal HepB -BD:  Hepatitis B vaccine strategy among infants  varies by geographic location 
within the country.  
 
Based on the request from the ACIP chair, we analyzed hepatitis B vaccination policies and schedule in 37 
countries which include , Canada, countries in the European Union  (EU)  (n=27)  and European Economic 
Area (EEA ) (Iceland, Liechtenstein, and Norway ), the United Kingdom  (UK) , Switzerland, Australia, New 
Zealand, South Korea and Japan and compared them to the United States.  
Among infants born to women with known HBV infection  (HBsAg positive women) , the  U.S. is aligned 
with  Canada, all EU /EEA countries ,  the United Kingdo m (UK), Switzerland, Australia, New Zealand, South 
Korea and Japan  which  all recommend the hepatitis B birth dose to be given at birth simultaneously with 
HBIG , either before discharge from the hospital or within 24 hours of birth.   

11 
 For infants born to  HBsAg -negative women , countries with a universal hepatitis B birth dose vaccination 
policy give all children the first dose following the same schedule as children born to HBsAg positive 
mothers.  
Among the 37 countries assessed,  26 implement selective HepB -BD for infants born to HBsAg -positive 
women  and the universal infant vaccination with three doses of hepatitis B vaccine to all infants 
irrespective of mothers ’ HBsAg status . Children born to HBsAg -negative mothers receive the first dose of 
hepatitis B vaccine by 3 months of age in 24 of the 26 countries  (18 countries at 2 months of age and 6 
countries at 3 months of age) .

High -income  countries base their decisions on vaccination schedule using cost -benefit and cost -
effectiveness assessments , especially countries  that provide free universal health care , along with 
epidemiological profile and high levels of maternal hepatitis B screening in the population. For example , 
in 2016 -2017, Japan and the United Kingdom switched from selective infant hepatitis B vaccination to 
universal infant vaccination after reviewing country -specific  epidemiological and cost -effectiveness data.  
In 2020, Slovenia switched from providing the first dose of hepatitis B at school entry to providing 
universal hepatitis B infant vaccination starting at 3 months of age.  To date, n o country in the world has 
reverted  from universal to selective hepatitis B vaccination schedules.

 Hepatitis B prevalence  and screening  in pregnant women  
Based on the request from the ACIP chair, we analyzed hepatitis B prevalence and screening among 
pregnant women in  37 countries which include: Canada, countries in the European Union (EU) (n=27) 
and European Economic Area (EEA) (Iceland, Liechtenstein, and Norway), the United Kingdom (UK), 
Switzerland, Australia, New Zealand, South Korea and Japan and compared them to  the United States.  
Prevalence estimates of hepatitis B among pregnant women were available in 20 of the 37 assessed 
countries. Overall, 9 countries had less than 0.5% prevalence of hepatitis B surface antigen among 
pregnant women while 8 countries reported a prevalence ranging from 0.5 to 0.9% and 3 countries 
reported a prevalence greater than 2% in pregnant women.  There are no data on the prevalence of 
hepatitis B in pregnant women in the United States in the last 10 years.  
Only 6 of the 3 7 selected countries have national registries that can track hepatitis B screening among 
pregnant women and estimate prevalence on an annual basis. The other 31 countries and the United 
States  do not track hepatitis B screening during pregnancy. In those countries, hepatitis B prevalence 
estimates when available  are based on surveys or special studies completed in previous years.

All of the 37 selected countries, except two, provide universal health care access to all citizens (includ ing 
residents and migrants) . 

13 
 Of the 29 countries that provide selective HepB -BD, five countries have national registries that can track 
the percentage of pregnant women screened for hepatitis B and subsequent care cascade of mother and 
infant. The remaining countries either have systems similar to the  perinatal hepatitis B  prevention 
program in the  U.S. or report positive hepatitis B test results to a national notifiable disease surveillance 
system . Unlike countries that provide selective HepB -BD, the United States does not have universal 
healthcare coverage with free access to antenatal care and vaccinations to the population. This is a 
critical difference between the United States and the countries that provide selective HepB -BD. 
As a result  of lack of adequate systems  to track screening in pregnant women and subsequent post -
exposure prophylaxis  in exposed infants , most of the countries with selective HepB -BD policies cannot 
track whether they are succeeding in preventing perinatal transmission of hepatitis B  on a regular basis  
(outside of special studies) . However, they provide universal healthcare to all the population with access 
to free antenatal care and vaccination services.  
To highlight the limited data availability in the 37 assessed countries, we compiled publicly available data 
on the percentage of pregnant women who are screened for hepatitis B surface antigen during 
pregnancy in each of those countries. Of the 37 countries selected to compare to the United States, only 
19 had publicly available data on percentage of pregnant women screened for hepatitis B.  Overall, 15  
countries reported that more than 90% of pregnant women are screened  for hepatitis B , which is the 
2030 g lobal indicator for validation of elimination.  The United States is one of five countries not meeting 
the 2030 global screening target . All countries that provide selective hepatitis B birth dose vaccination 
that have available antenatal screening data  have achieved the 90% global antenatal screening coverage 
target for hepatitis B.
