Us Children And Adult Hepatitis B Vaccine Schedules
*Please note that the first dose should be given as soon as possible. Additional doses require minimum time intervals between doses in order for the vaccine to be effective.
3-Dose Vaccine Series for Children and Adults
The hepatitis B vaccine is an injection that is generally given in the arm as a three-dose series on a 0, 1, and 6-month schedule. Alternative schedules may be considered, noting that a third dose at 6 months, meeting minimum intervals between doses, is needed for maximum, long-term protection. Completing the hepatitis B vaccine series, preferably beginning at birth, will ensure protection against hepatitis B, hepatitis delta and lower the lifetime risk of liver cancer. 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 infection, which makes the birth dose essential to their protection.
There are four, 3-dose vaccine brands approved in the U.S.
- PreHevbrio PreHevbrio is only approved for adults age 18 and over.

What Does It Mean When Hepatitis B Is Reactive
HBsAg : when this is positive or reactive, it means the person is currently infected with hepatitis B and is able to pass the infection on to others.
Is hepatitis B reactive curable?
Theres no cure for hepatitis B. The good news is it usually goes away by itself in 4 to 8 weeks. More than 9 out of 10 adults who get hepatitis B totally recover. However, about 1 in 20 people who get hepatitis B as adults become carriers, which means they have a chronic hepatitis B infection.
What is reactive and non reactive in hepatitis B?
Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months.

Will My Immunization Be Recorded
Your immunization records are registered in a computerized network known as the Immunization Records and Yellow Cards. While this one is specific to Ontario, each province has their own.
They can use information obtained in these databases to:
- Maintain immunization data
- Inform you whether or when you or your family members need an immunization
- Track how well vaccinations perform to prevent vaccine-preventable infections
You can also share your immunization history with health care providers for the provision of social health services to aid with assessment and treatment and monitor the spread of infectious illnesses.

How Long Does A Hepatitis A Vaccine Last

Hepatitis A is a highly contagious disease of the liver that can cause severe symptoms, such as fever, nausea, vomiting, stomach or joint pain, tiredness and jaundice. While the disease is rarely fatal, it can cause liver failure, most typically in those ages 50 and older, according to the Centers for Disease Control and Prevention. The disease is transmitted via consuming contaminated foods or drinks, or through some form of close contact with an infected person.
Is It Okay To Get An Extra Dose Of Hepatitis B Vaccine
Yes. Although extra doses of vaccine are not recommended, you can think of the extra dose as another chance for the immune system to see the hepatitis B virus. A vaccine is not the only time the immune system will see the virus or bacteria contained in it. People may be exposed to the virus or bacteria at school or the store or when visiting family or friends. An extra dose of vaccine is like one more exposure, except the difference is that the virus or bacteria in any vaccine has been made safe, so it wont make you ill.

Hi Everich,
You need to be a bit more specific about what the exact test was. What is all the information you have about the test? We cannot answer your question without that information.

Hi Everich, there are basically 3 blood tests that are required for a new vs. a chronic hepatitis B infection. Below is a simple summary of these tests. If you could let us know which blood test was indeterminate that would be very helpful.
Hepatitis B surface antigen If or means the hep b virus is present. This could mean a new infection or a chronic infection . If this test is or , then the hep b virus is not present in the blood.
Hepatitis B surface antibody this tests for a protective antibody against the hep b virus. This can occur through getting the hep b vaccine or recovery from an exposure to the virus. If or , then it means a person has been protected against the hep b virus either through vaccination or recovery from an infection. Generally, the above test will be or .

Persons With Inadequate Immunization Records
Evidence of long term protection against HB has only been demonstrated in individuals who have been vaccinated according to a recommended immunization schedule. Independent of their anti-HBs titres, children and adults lacking adequate documentation of immunization should be considered susceptible and started on an immunization schedule appropriate for their age and risk factors. Refer to Immunization of Persons with Inadequate Immunization Records in Part 3 for additional information.
Are Hepatitis B Virus Infections Easily Avoided
Large quantities of hepatitis B virus are present in the blood of people with hepatitis B in fact, as many as one billion infectious viruses can be found in a milliliter of blood from an infected individual. Therefore, hepatitis B virus is transmitted in the blood of infected individuals during activities that could result in exposure to blood, such as intravenous drug use, tattooing, or sex with people who are infected. However, it is also possible to catch hepatitis B virus through more casual contact, such as sharing washcloths, toothbrushes or razors. In each of these cases, unseen amounts of blood can contain enough viral particles to cause infection. In addition, because many people who are infected don’t know that they are infected, it is very hard to avoid the chance of getting infected with hepatitis B virus.

Immunisation Against Hepatitis B For Children
Vaccination is the best protection against hepatitis B infection and is recommended for all infants and young children, adolescents and those in high-risk groups. Vaccination can be with a vaccine against hepatitis B alone or with a combination vaccine.
Protection against hepatitis B is available free of charge under the National Immunisation Program Schedule.
In Victoria, vaccination against hepatitis B is free for all babies and children including:
- Babies at birth vaccinate with hepatitis B vaccine as soon as possible after birth.
- Babies at 2, 4 and 6 months immunisation in the form of a diphtheria, tetanus, whooping cough, hepatitis B, polio and Haemophilus influenzae type b vaccine .
- Premature babies at 12 months premature babies born under 32 weeks gestation or under 2,000g birth weight receive a single booster dose.
- Children up to and including 20 years of age.
Results And Next Steps
The results of a hepatitis B titer panel can help a doctor determine a persons hepatitis B status. The results can be confusing if a person has never been through this type of testing before, but the doctor can explain the findings.
The results for the titer come back as either negative or positive on each subtest of the panel. Positive means that the virus or antibodies showed up on the test, while negative means that they did not.
The following table outlines what positive and negative results mean on different parts of the test and the possible next steps.

Who Shouldnt Get The Vaccine
It is worth noting that individuals who had serious allergic reactions to the first dose of the vaccine should not proceed with the second and third. Also, those hypersensitive to yeast shouldnt take the vaccine. People suffering from severe acute illnesses should wait until their condition is improved.
The Hepatitis B Vaccine
The hepatitis B vaccine is used to prevent hepatitis B. Its usually provided in three doses.
The first dose can be taken on a date you choose. The second dose must be taken 1 month later. The third and final dose must be taken 6 months after the first dose.
Some people may need two or four doses of this vaccine.
There is also a newer hepatitis B vaccine thats offered in two doses.

How And When Do Doctors Give Vaccines
For the hepatitis A vaccine:
You should get two doses, given as shots, 6 months apart for complete protection. The virus in the vaccine is killed .
Children should get the first dose between 12 and 23 months of age. Children older than age 2 can get the first dose at their next doctorâs visit.
If you need the vaccine because of upcoming travel, get it at least 1 month before you go.
For the hepatitis B vaccine:
For long-lasting immunity, you need three to four doses, depending on which type of vaccine is used. You get them as shots.
Children should get their first dose at birth and complete the series by age 6 months. Usually, the baby would get a second dose at 1 month old and the third dose at 6 months.
Babies born to women who have hepatitis B need a shot of hep B antibodies, as well as their first hep B vaccine shot, when theyâre born. They will also need follow-up blood tests to make sure theyâre OK.
Catch-up vaccinations are recommended for children and teens who were never vaccinated or who did not get all three shots.
If you’re an adult who wants to be vaccinated, you should talk about it with your doctor or pharmacist. If you are considering both vaccines, ask your doctor about vaccines that combine hep A and B.

Why Should I Vaccinate My Newborn Child If I Know That I Am Not Infected With Hepatitis B Virus
Before the hepatitis B vaccine, every year in the United States about 18,000 children were infected with hepatitis B virus by the time they were 10 years old. This statistic is especially important because people are much more likely to develop liver cancer or cirrhosis if they are infected early in life, rather than later in life .
About 9,000 of the 18,000 children infected in the first 10 years of life caught the virus from their mother during birth. However, many young children didnt catch the disease from their mother. They caught it from either another family member or someone else who came in contact with the child. Because hepatitis B can be transmitted by relatively casual contact with items contaminated with the blood of an infected person, and because many people who are infected with hepatitis B virus dont know that they have it, it is virtually impossible to be careful enough to avoid this infection.
For these reasons, all young children are recommended to receive the hepatitis B vaccine. The best time to receive the first dose is right after birth. This will ensure that the child will be protected as early as possible from catching hepatitis B from people who dont know that they are infected with the virus.

Babies And Hepatitis B Vaccination
Pregnant women have a routine blood test for hepatitis B as part of their antenatal care.
Babies born to mothers infected with hepatitis B need to be given a dose of the hepatitis B vaccine within 24 hours of their birth, followed by further doses at 4, 8, 12 and 16 weeks of age, plus a final dose when they’re 1 year old.
Babies of mothers identified by the blood test as particularly infectious might also be given an injection of HBIG at birth on top of the hepatitis B vaccination to give them rapid protection against infection.
All babies born to mothers infected with hepatitis B should be tested at 1 year of age to check if they have become infected with the virus.
What Hepatitis B Immunisation Involves
Full protection involves having 3 injections of the hepatitis B vaccine at the recommended intervals.
Babies born to mothers with hepatitis B infection will be given 6 doses of hepatitis B-containing vaccine to ensure long-lasting protection.
If you’re a healthcare worker or you have kidney failure, you’ll have a follow-up appointment to see if you have responded to the vaccine.
If you have been vaccinated by your employer’s occupational health service, you can request a blood test to see if you have responded to the vaccine.

Silent Infections In Hbsag Negative Babies
The six subjects who remained positive for anti-HBc during the follow up were considered to have been infected at birth or during infancy, although the exact time of infection could not be assessed from these results. For the 231 neonates who did become anti-HBc negative during the study, anti-HBc reappeared in 14 blood samples among 6.1% of subjects . Therefore, when considering the number of subjects who were either continuously anti-HBc positive or who had reappearance of anti-HBc, 20 silent infections occurred during the follow up. Five of the 14 anti-HBc reappearances were without a simultaneous anti-HBs rise : one child in group 1 B was positive at months 60 and 61 one child in group 1 NB was positive at months 60, 84, and 96 another in group 2 NB was positive at months 24, 36, 48 and then lost to follow up and the remaining two children were positive at months 36, 60, and subsequently lost to follow up . In the five blood samples from five neonates before the reappearance of anti-HBc, 60% had anti-HBs titres below 100 mU/ml, with a GMT of 75 mU/ml. In the nine neonates who had an anti-HBc reappearance also accompanied by an anti-HBs rise , 78% had anti-HBs titres < 100 mU/ml with a GMT of 36 mU/ml.

International Hepatitis B Vaccine Schedules
*Please note that the first dose should be given as soon as possible. Additional doses require minimum time intervals between doses in order for the vaccine to be effective.
The hepatitis B vaccine is an injection that is generally given in the arm and as a three-dose series. The World Health Organization recommends a 0, 1, and 6-month vaccine schedule, though schedules may vary based on a countrys national immunization program. Completing the hepatitis B vaccine series, preferably beginning at birth, will ensure protection against hepatitis B, hepatitis delta and lower the lifetime risk of liver cancer. 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 infection, which makes the birth dose essential to their protection. Please note that the vaccine brand name, manufacturer and associated schedules for adults, children and infants may be unique to different countries, though there is a list of WHO prequalified vaccines.
3-Dose Vaccine Series for Infants
The World Health Organization recommends all infants receive the first dose of the hepatitis B vaccine within 24 hours of birth and to complete the vaccine series with additional shots at 1 month and 6 months of age. Beginning the hepatitis B vaccine at birth will ensure protection against hepatitis B for life.

Immunisation Against Hepatitis B
The current Australian immunisation program provides free hepatitis B vaccine to protect all children against the hepatitis B virus.
A full course of hepatitis B injections must be given for a child to be protected. It is recommended that this course begins within 24 hours of birth with a vaccine against hepatitis B alone. Further doses are routinely given at 2 months , 4 months and 6 months of age, as a combination vaccine.
Vaccination is the best protection against hepatitis B infection. In Victoria a free hepatitis B vaccine is available for a number of groups at high risk, including but not limited to Aboriginal and Torres Strait Islander peoples, men who have sex with men, and people living with HIV.
The adult course involves 3 doses of the vaccine over 6 months and gives protection to about 95 per cent of people. Once you have had the 3 doses, you can have a blood test to see if you are protected.
