The hepatitis B vaccine is a safe and effective way to prevent hepatitis B, a liver disease that can cause mild illness or lead to serious, lifelong illness. The World Health Organization (WHO) recommends that all newborns receive the first dose of the hepatitis B vaccine within 24 hours of birth, with additional shots at 1 month and 6 months of age. This is because greater than 90% of babies and up to 50% of young children who are not vaccinated and are infected with hepatitis B will have lifelong infections. However, the timing of the hepatitis B vaccine can vary depending on a country's national immunization program and the vaccine brand. For example, the 2-dose Heplisav-B vaccine is recommended for adults aged 18 and older in the US and is administered as two doses one month apart, without the need for a booster dose. The 3-dose Engerix-B vaccine can be given on an accelerated 4-dose schedule, with 3 shots administered within 2 months and a booster dose at 1 year.

What You'll Learn
Hepatitis B vaccine schedule for newborns
The hepatitis B vaccine is safe and effective and offers long-term protection against acute and chronic infection. It is recommended for all newborns and infants. The World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC) both advise that all newborns receive the hepatitis B vaccine.
The vaccine schedule for newborns depends on the mother's HBsAg status. If the mother is HBsAg positive, the baby must get the vaccine within 12 hours of birth, along with a hepatitis B immune globulin (HBIG) shot for immediate protection. The baby will then need three additional doses, for a total of four doses. The final dose should not be administered before 24 weeks of age.
If the mother is HBsAg negative, the baby can receive the vaccine within 24 hours of birth. If the baby has a low birth weight, the first dose should be given at one month of age or at hospital discharge, whichever comes first. The baby will then receive two additional doses, for a total of three doses.
The second shot should be administered at least one month (or 28 days) after the first, and the third shot should be given at least four months (16 weeks) after the first and two months after the second. Infants should be a minimum of 24 weeks old when they receive the third shot.
It is important to note that the birth dose of the vaccine is not counted as part of the required doses to complete the series. The hepatitis B vaccine can also be given in combination with other vaccines, such as DTaP, IPV, Hib, or HepA.

Hepatitis B vaccine for children and adolescents
Hepatitis B is an incurable and potentially fatal infection that can lead to liver disease, cancer, and death. The best way to prevent hepatitis B is by getting vaccinated. The hepatitis B vaccine is safe and effective for children and adolescents, and it has sharply cut infections in children. It is recommended that all infants receive the hepatitis B vaccine at birth. This is because hepatitis B can be transmitted from mother to child during delivery, and vaccinating newborns before they leave the hospital protects them from being infected throughout childhood.
The Advisory Committee on Immunization Practices (ACIP) recommends that unvaccinated children younger than 19 years of age also receive the hepatitis B vaccine. People aged 19 years and younger should receive three doses of the vaccine. The hepatitis B vaccine can be given as a standalone vaccine or as part of a combination vaccine, such as Twinrix or Pediarix. The birth dose of the vaccine should not be counted as part of the three doses required to complete the HepB series. Three additional doses should be administered according to the recommended schedule. The final dose in the series should not be administered before 24 weeks of age.
It is important to note that vaccinating newborns just after delivery gives their immune system the best chance to fight off the infection. Studies have shown that vaccinating older babies exposed to hepatitis B is not as effective. However, if a child or adolescent misses a dose of the hepatitis B vaccine, they should get the next dose as soon as possible.

Hepatitis B vaccine for adults
Hepatitis B is a liver disease caused by the hepatitis B virus (HBV). The best way to prevent hepatitis B is by getting vaccinated. The hepatitis B vaccine is safe and effective, and most people do not experience any side effects. Soreness at the injection site is the most common side effect.
The Advisory Committee on Immunization Practices (ACIP) recommends hepatitis B (HepB) vaccination for all adults aged 19–59 and adults aged 60 and older with risk factors for hepatitis B. Adults aged 60 and older without known risk factors may also receive the hepatitis B vaccine. The CDC also recommends hepatitis B vaccination for adults on dialysis or predialysis, who should receive three doses of the dialysis formulation.
There are several types of hepatitis B vaccines available in the United States, including Engerix-B, Heplisav-B, and Recombivax HB, which are all single-antigen vaccines, and Twinrix, Pediarix, Vaxelis, and Hepatis-B, which are combination vaccines. Twinrix is a 4-dose vaccine that can be given on an accelerated schedule, with three doses administered within one month, followed by a booster shot at one year. Heplisav-B is a 2-dose vaccine, with doses administered one month apart, and does not require a booster dose for long-term protection. The World Health Organization (WHO) recommends a 0, 1, and 6-month vaccine schedule for the hepatitis B vaccine, though schedules may vary depending on the country's national immunization program.
It is important to consult with a healthcare provider to determine which vaccine is right for you and to receive the vaccination.

Hepatitis B vaccine for international travellers
International travel increases your chances of getting and spreading diseases that are rare or not found in your home country. The Hepatitis B vaccine is a common choice for those travelling on short notice outside the US. The World Health Organization (WHO) recommends that all infants receive the first dose of the hepatitis B vaccine within 24 hours of birth, with additional shots at 1 month and 6 months of age. This will ensure protection against hepatitis B for life.
The hepatitis B vaccine is an injection given in the arm as a two- or three-dose series, depending on the vaccine brand. The two-dose vaccine is recommended for adults in the US aged 18 and older, with the doses given one month apart. The three-dose vaccine is recommended for people aged 19 and younger, and people aged 20 and older. Adults on haemodialysis should receive four doses. The three-dose vaccine can be given on an accelerated, four-dose schedule, with three shots administered within two months and a booster dose at one year to provide maximum long-term protection.
If you are an international traveller, it is important to check the CDC's webpage for your destination to see what vaccines or medicines you may need. Make an appointment with your healthcare provider at least four to six weeks before you leave to get destination-specific vaccines, medicines, and information. It is also important to bring a copy of your official immunization records with you when you travel.

Hepatitis B vaccine side effects
Hepatitis B vaccination is the most effective means of interrupting HBV transmission. It is safe and effective, and most people do not experience any side effects. However, as with any medicine, there is a small risk of side effects. Soreness at the injection site is the most common side effect. Other possible side effects include fever, rash, and joint aches or pain. These side effects are typically mild and do not require medical attention.
It is important to note that the Hepatitis B vaccine cannot give you the hepatitis B virus (HBV) or the human immunodeficiency virus (HIV). The vaccine is made without any human blood or blood products, and it does not cause MS or other autoimmune conditions. The Vaccine Adverse Event Reporting System (VAERS) is an early warning system co-managed by the CDC and FDA that monitors for potential vaccine safety problems. The system has found no differences in deaths between vaccinated and unvaccinated newborns.
The Hepatitis B vaccine is recommended for all newborn babies, infants, children, adolescents up to 19 years of age, and adults with risk factors or seeking protection. Pregnant women who are infected with hepatitis B or are carriers of the virus can pass the disease to their babies, so vaccination is important for this group as well. The vaccine is also recommended for people in areas with a high risk of HBV infection, such as Alaskan Eskimos, Pacific Islanders, and refugees from areas with high rates of hepatitis B.
There are several types of Hepatitis B vaccines available, and your doctor can help you determine which one is right for you. The PREHEVBRIO vaccine is the only one that does not contain yeast, making it safe for people with yeast allergies. Studies have shown that the Hepatitis B vaccine is safe for breastfeeding women and their infants, and it does not interfere with other medicines. However, it is important to consult your healthcare provider if you have any concerns or questions about the vaccine.
