The Hepatitis B vaccine has been recommended for newborns in the United States since 1991, when the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control (CDC) advised that all infants receive the first dose at birth. Before this, the vaccine was only recommended for high-risk groups, including gay men, injection drug users, and healthcare workers. The vaccine was first approved in the US in 1981, and in the following decade, health officials issued evolving guidelines on who should receive it. Many countries now routinely vaccinate infants against hepatitis B, and it is on the World Health Organization's List of Essential Medicines.

The first hepatitis B vaccine was approved in 1981
The first hepatitis B vaccine, Heptavax-B, was approved by the FDA in the United States in November 1981. It was developed by Maurice Hilleman and his team, and it was composed of antigens from human serum harvested from several IV drug users and homosexual men.
In the years following its approval, the vaccine was recommended for individuals considered at moderate to high risk of contracting hepatitis B. This included IV drug users, homosexual males, individuals with multiple sexual partners, newborn infants of hepatitis B-positive mothers, and healthcare workers and patients exposed to blood and blood products.
The Advisory Committee on Immunization Practices (ACIP) played a key role in recommending the vaccine for these high-risk groups. However, despite their efforts, the prevalence of hepatitis B did not decrease and instead increased, with high rates among young adults. This led to a shift in strategy, and in 1991, the ACIP recommended universal infant vaccination against hepatitis B. This decision was made because vaccinating individuals engaged in high-risk behaviours had not been widely effective, and many infected people had no identifiable source for their infections.
The recommendation for universal newborn hepatitis B vaccination was supported by the Committee on Infectious Diseases of the American Academy of Pediatrics (AAP), despite limited knowledge about newborns' immune and neurological systems. This marked a significant shift in the approach to hepatitis B prevention, and today, most newborns in the United States are vaccinated against the virus, usually in the first few days of life.
The hepatitis B vaccine is crucial in preventing mother-to-child transmission and minimizing the risk of infection from other household members. It effectively protects infants from the potential long-term effects of hepatitis B, including liver failure, cirrhosis, and liver cancer.

Vaccination of newborns reduces the risk of infection
Vaccination is a crucial aspect of modern healthcare, protecting individuals and populations from a range of diseases. The focus on vaccinating newborns is particularly important as they are highly susceptible to infections. Vaccinating newborns reduces their risk of infection and offers long-term protection, as evident in the case of the Hepatitis B vaccine.
The Hepatitis B vaccine has been recommended for newborns since 1991 by the US CDC ACIP. This vaccine is one of the few routinely administered at birth in the United States. The recommendation extends to infants born to mothers with positive or unknown Hepatitis B status, aiming to prevent mother-to-child transmission.
Hepatitis B infection in newborns can have severe long-term consequences, including liver failure, cirrhosis, and liver cancer. Vaccination at birth is crucial as infants are highly vulnerable to infection during their early months. Studies indicate that 90% of infected infants will develop chronic symptoms later in life, highlighting the importance of timely vaccination.
While some parents may question the need for vaccinating newborns against sexually transmitted infections like Hepatitis B, it is essential to understand the risks of mother-to-child transmission and the potential for life-long complications. Properly identifying infected mothers is challenging due to test inaccuracies, emphasizing the importance of newborn vaccination.
In addition to Hepatitis B, newborns may receive other vaccines, such as Bacillus Calmette-Guérin (BCG), which has proven safe and effective. Vaccinating newborns is a global health priority due to their high risk of infection and the potential for effective disease prevention through immunization.
Furthermore, vaccinations are vital for preterm babies, who are at an increased risk of health complications from diseases. The only vaccine that may be delayed in preterm infants is Hepatitis B, but it is still recommended within the first 24 hours of birth if possible.

Hepatitis B vaccination is recommended for infants born to Hepatitis B-positive mothers within 12 hours of birth
Hepatitis B is a serious disease with long-term chronic health issues, such as liver failure, cirrhosis, and liver cancer. It is recommended that all infants receive the hepatitis B vaccine soon after birth. This is to prevent the transmission of hepatitis B from mother to child, as well as to prevent infection from other infected persons living in the household.
The hepatitis B vaccine is especially crucial for infants born to Hepatitis B-positive mothers. These infants have a greater than 90% chance of developing chronic hepatitis B if they are not treated at birth. Therefore, it is recommended that they receive the hepatitis B vaccine within 12 hours of birth, along with a dose of hepatitis B immune globulin (HBIG). This combination provides superior protection for these infants.
The World Health Organization (WHO) recommends that all babies receive the hepatitis B vaccine within 24 hours of birth, and this is known as the "birth-dose". This recommendation is to ensure complete protection against hepatitis B, which is a leading cause of liver cancer worldwide. The birth-dose is particularly important for infants born to Hepatitis B-positive mothers, as it can prevent the transmission of the virus from mother to child.
In the United States, the CDC ACIP first recommended the hepatitis B vaccine for all newborns in 1991. This was the first time that a vaccine was routinely recommended for all newborns in the country. The CDC has varying hepatitis B vaccination schedule recommendations depending on the birth weight of the infant and the Hepatitis B status of the mother. For infants born to mothers with a negative Hepatitis B antigen test and a birth weight of at least 2000 grams, the first vaccination is recommended in the first 24 hours of life. For infants born to mothers with a negative Hepatitis B antigen test and a birth weight of less than 2000 grams, the first vaccination is recommended at one month of age or hospital discharge, whichever comes first.
It is important to note that the hepatitis B vaccine is safe and effective, and it does not cause sudden infant deaths (SIDs), autism, multiple sclerosis, or other neurological disorders. The side effects are usually mild and may include soreness, swelling, redness, low fever, headache, tiredness, and loss of appetite at the injection site.

The CDC recommends vaccinating infants soon after birth and before hospital discharge
The Hepatitis B vaccine was first approved in the United States in 1981, with a recombinant version becoming available in 1986. In the following decade, U.S. health officials issued evolving guidelines on who should receive the vaccine. Initially, it was recommended for gay men, injection drug users, and healthcare workers. Later, it was suggested for children of hepatitis B-positive women, and eventually, all newborns.
The Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control (CDC) recommended in 1991 that all infants receive the first dose of the hepatitis B vaccine at birth and before hospital discharge. This recommendation was supported by the Committee on Infectious Diseases of the American Academy of Pediatrics (AAP), despite limited knowledge about newborns' immune and neurological systems at that time.
The CDC's recommendation for universal newborn hepatitis B vaccination was based on the evolving understanding of the disease and its potential impact on infants. It is important to note that hepatitis B infection in infants can lead to long-term chronic health issues such as liver failure, cirrhosis, and liver cancer. By vaccinating at birth, the risk of infection from the mother or other infected individuals is minimized, providing the greatest preventative effect for the infant population.
Furthermore, properly identifying infected mothers is challenging due to possible errors in testing and result interpretation. Administering the vaccine soon after birth helps prevent infection in infants born to mothers with the virus in their blood, even if the mother's hepatitis B status is unknown. For infants born to hepatitis B-positive mothers, the CDC recommends the vaccine within the first 12 hours of birth, along with hepatitis B immune globulin.
The CDC's recommendation for newborn hepatitis B vaccination remains in place today, and most newborns in the United States are vaccinated against the virus within the first few days of life. This proactive approach helps protect infants from the potential lifelong complications of hepatitis B infection and ensures they receive the necessary protection before leaving the hospital.

The vaccine is routinely given to newborns in many countries
The hepatitis B vaccine is routinely given to newborns in many countries, including the United States. The first hepatitis B vaccine was approved in the US in 1981, and in the decade that followed, health officials issued evolving guidelines on who should receive it. Initially, it was recommended for gay men, injection drug users, and healthcare workers; later, it was suggested for children of hepatitis B-positive women, and eventually, all newborns.
In 1991, the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control (CDC) recommended that all infants receive the first dose of the hepatitis B vaccine at birth before hospital discharge. This recommendation was made due to the realisation that vaccinating only high-risk groups was not sufficient, as many infected people had "no identifiable source for their infections". The ACIP's 1991 recommendation for universal newborn hepatitis B vaccination was supported by the Committee on Infectious Diseases of the American Academy of Pediatrics (AAP), despite limited knowledge about newborns' immune and neurological systems at the time.
State laws mandating the hepatitis B vaccine for all children were accepted in the 1990s, and today, most newborns in the US are vaccinated against the virus within the first few days of life. The CDC has varying hepatitis B vaccination schedule recommendations depending on the birth weight of the infant and the hepatitis B status of the mother. For infants born to mothers with a negative hepatitis B antigen test and weighing at least 2000 grams, the first vaccination is recommended within the first 24 hours of life, followed by a second dose between 1 and 2 months, and a third dose between 6 and 18 months. For infants born to mothers with an unknown hepatitis B status or those weighing less than 2000 grams, the first vaccination is recommended within the first 12 hours of life.
Vaccinating newborns against hepatitis B is crucial as many infants who become infected contract the disease from their unknowingly infected mothers during birth. Properly identifying infected mothers is challenging due to potential errors in testing and result interpretation. Administering the vaccine soon after birth minimises the risk of infection from the mother or other infected individuals in the household. Additionally, the vaccine can help prevent infection in infants born to mothers with the virus in their blood. Studies indicate that the long-term chronic health issues associated with hepatitis B, such as liver failure, cirrhosis, and liver cancer, are more likely to occur when the infection is acquired at a younger age. For example, 90% of infants infected with hepatitis B will develop chronic symptoms later in life, whereas the chronic effects are less prominent when the illness is contracted later in life.
In countries with high rates of hepatitis B infection, vaccinating newborns has not only reduced the risk of infection but has also led to a significant reduction in liver cancer. For example, Taiwan's implementation of a nationwide hepatitis B vaccination program in 1984 was associated with a decline in childhood hepatocellular carcinoma.
