The hepatitis B vaccine is safe and effective for all ages and is recommended for everyone from birth to 59 years. The World Health Organization (WHO) recommends that all newborns receive the first dose of the hepatitis B vaccine within 24 hours of birth, and the vaccine series can be completed with additional shots at 1 month and 6 months of age. Infants born to mothers with hepatitis B are at extremely high risk and must receive the first dose in the delivery room or within the first 12-24 hours of life. For those aged 19 and younger, three doses are recommended, while those aged 20 and older should receive three to four doses. However, adults on dialysis or predialysis should receive three doses of the dialysis formulation, and adults on hemodialysis should receive four doses. The hepatitis B vaccine is also recommended for adults with diabetes and those at high risk of infection due to their jobs, lifestyle, living situations, or country of birth. While there are no known harms, individuals previously infected with hepatitis B will not benefit from vaccination as it will not clear the virus. Additionally, those who have had serious allergic reactions to the vaccine or its components, such as yeast, should not receive the vaccine.

Hep B vaccine dosage and schedule
The Hep B vaccine is generally administered as an injection in the arm. The World Health Organization (WHO) recommends a 0, 1, and 6-month vaccine schedule, though schedules may vary depending on the country's national immunization program. The vaccine is typically given in a series of three doses, with the first shot administered at any time, the second shot at least one month later, and the third shot at least four months after the first shot and two months after the second. Infants should be a minimum of 24 weeks old when receiving the third dose.
For those who need an accelerated schedule, a booster dose at one year is necessary to ensure long-term protection. The Heplisav-B vaccine is a 2-dose series that can be completed in one month, compared to the six months required for other vaccine series. This vaccine is a suitable choice for those with hyporesponsive conditions, such as diabetes, or those who have previously struggled to respond to the vaccine. It is also identified by the U.S. Department of Health and Human Services as the preferred vaccine for unvaccinated individuals living with HIV.
Engerix-B is a 3-dose vaccine that can be administered on an accelerated 4-dose schedule, with three shots given within two months and a booster dose at one year for maximum long-term protection. Twinrix is another 4-dose vaccine that can be given on an accelerated schedule, providing protection against hepatitis A and B. This vaccine involves three doses within one month, followed by a booster shot at one year. This option is commonly chosen by those travelling outside the U.S. at short notice.
The dosage and schedule for the Hep B vaccine depend on the age and health status of the individual. People aged 19 years and younger, as well as those aged 20 and older, should receive three doses. Adults on hemodialysis or predialysis should receive four doses. Pregnant patients and those on dialysis should be vaccinated with Engerix-B, Heplisav-B, Recombivax HB, or Twinrix. People aged 18 years and older should receive either three or four doses.
It is important to note that the Hep B vaccine is recommended for all newborns, children up to 18 years of age, adults up to 59 years, and adults 60 and older who are at high risk of infection or seeking protection. Babies born to infected mothers must receive the first dose within the first 12 hours of life, preferably in the delivery room. The vaccine provides lifetime protection against hepatitis B and is safe for all, including pregnant women.

Who should get the Hep B vaccine?
The Hepatitis B vaccine is recommended for several groups of people. Firstly, all newborns and infants should receive the vaccine at birth. This is because the perinatal period is one of the highest-risk times for Hep B transmission to infants. After this, the vaccine is recommended for children up to the age of 18 or 19, with those under 6 receiving three doses and those under 18 receiving two or three doses.
The Hep B vaccine is also recommended for adults aged 19-59 and those over 60 with risk factors for Hep B. Risk factors include being at high risk of infection due to your job, lifestyle, living situation, country of birth, or being sexually active with multiple partners. Other risk factors include having diabetes, end-stage renal disease, or engaging in intravenous drug use.
The Hep B vaccine is also recommended for adults over 60 without known risk factors, and for pregnant or breastfeeding women. The vaccine is safe for pregnant women and can protect newborns. However, those who are allergic to yeast should not receive the vaccine, except for PreHevbrio, which is yeast-free.

Who should not get the Hep B vaccine?
The Hepatitis B vaccine is generally recommended for everyone, including newborns, children, and adults. However, there are certain cases where individuals should not receive the vaccine or should consult a doctor before vaccination. Here are the groups who should not get the Hep B vaccine or should exercise caution:
Individuals with Previous Hepatitis B Infection
If you have previously had a hepatitis B infection (HBsAg positive), the Hep B vaccine series will not benefit you or clear the virus. The vaccine is intended to provide protection for those who have not been infected. However, it's important to note that there is no known harm in receiving the Hep B vaccine after recovering from a past infection.
Individuals with Allergic Reactions
According to the Centers for Disease Control and Prevention (CDC), individuals who have experienced serious allergic reactions to the Hep B vaccine, any part of the vaccine, or yeast in the past should not receive the vaccine. While yeast is not an ingredient in the vaccine, residual yeast-derived proteins may be present in the final product.
Pregnant or Breastfeeding Women
Pregnant or breastfeeding women should consult their doctors about the most suitable vaccine options. In some cases, specific vaccine brands may be recommended for these individuals.
Adults on Dialysis
Adults who are on dialysis or predialysis should receive the recommended number of doses of the dialysis formulation. It is important to follow the advice of healthcare providers regarding the appropriate vaccine and dosage for this group.
Infants Below 2,000 g at Birth
In the United States, medically stable infants with a birth weight of at least 2,000 g are recommended to receive the first dose of the Hep B vaccine within 24 hours of birth. Infants weighing less than this should consult a healthcare provider for specific guidance.
It is always advisable to consult a healthcare professional or your doctor to determine if the Hep B vaccine is suitable for your individual circumstances. They can provide personalized advice and recommendations based on your medical history and current health status.

Hep B vaccine safety
The Hep B vaccine is considered safe for most people. It is recommended for all newborns, children up to 18 years of age, and adults at high risk of infection. The World Health Organization (WHO) recommends that all infants receive the first dose of the Hep B vaccine within the first 12-24 hours of life, especially those born to mothers with Hep B. This is because infants born to infected mothers are at extremely high risk of becoming chronically infected after delivery.
The Hep B vaccine is also recommended for adults living with diabetes and those at high risk of infection due to their jobs, lifestyle, living situations, country of birth, or other factors. For example, people who are sexually active and are not in a long-term, mutually monogamous relationship may be at higher risk of contracting Hep B. Additionally, individuals with end-stage renal disease or on dialysis may require a different dosage or an additional booster shot.
The Hep B vaccine is a series of two or three shots, depending on the brand. It is important to receive all doses to be fully protected. The shots are typically given over a 6-month period, with the second dose administered at least one month after the first, and the third dose at least four months after the first and two months after the second. However, if a dose is missed, it is okay to get it as soon as possible, and there is no need to restart the series.
The Hep B vaccine does not contain any live virus, and you cannot get Hep B from the vaccine. The most common side effect is soreness at the injection site, and most people do not experience any side effects at all. However, as with any medicine, there is a small chance of a serious problem occurring. It is recommended to consult a doctor to determine the most suitable vaccine and to discuss any potential risks.
