Routine Administration Schedule For Hepatitis B Vaccine In Adults
- The dosing schedule is 0, 1 to 2 months, and 4 to 6 months.
- There is some flexibility in the schedule, but be sure to keep in mind the minimum intervals between doses:
- At least four weeks between doses #1 and #2
- At least eight weeks between doses #2 and #3
- At least 16 weeks between doses #1 and #3
- If your patient falls behind on the hepatitis B vaccination schedule , continue vaccinating from where your patient left off. The series does NOT need to be restarted.
Emergency Hepatitis B Vaccination
If you’ve been exposed to the hepatitis B virus and have not been vaccinated before, you should get immediate medical advice, as you may benefit from having the hepatitis B vaccine.
In some situations, you may also need to have an injection of antibodies, called specific hepatitis B immunoglobulin , along with the hepatitis B vaccine.
HBIG should ideally be given within 48 hours, but you can still have it up to a week after exposure.
What Is Hepatitis B Vaccine
Hepatitis B vaccine gives protection against infection from the hepatitis B virus. The vaccine works by causing the body to produce antibodies against the virus responsible for hepatitis B infection and in this way protects against the disease. Hepatitis B is a virus that is easily spread through contact with the blood or bodily fluids of an infected person. For example, it can be passed on through unprotected sex, by sharing injection gear, through a needle stick injury or from mother to child during childbirth. Hepatitis B infection can cause serious problems including liver failure, cirrhosis, and liver cancer. Preventing infection can prevent these problems. Read more about hepatitis 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 didn’t 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 blood of an infected person, and because many people who are infected with hepatitis B virus don’t 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.
Listen to Dr. Offit explain why newborns get the hepatitis B vaccine by watching this short video, part of the series Talking About Vaccines with Dr. Paul Offit.
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’ve become infected with the virus.

Why Do You Need A Hepatitis B Shot
Hepatitis B is a viral infection that cant be transferred person-to-person unless you have contact with an infected persons bodily fluids. Annual infection rates of HBV are going down in the United States thanks to vaccines. So you might be wondering if you or your child needs a shot to protect against hepatitis B.
Who Should Get The Hbv Vaccine
The Centers for Disease Control and Prevention recommends that children should get their first hepatitis B vaccine at birth and complete the doses by 6 to 18 months of age. However, the HBV vaccine is still recommended for all children if they havent already gotten it, from infanthood up to 19 years old. Most U.S. states require a hepatitis B vaccine for school admittance, however.
Its also recommended for adults at an increased risk of catching the HBV infection, or anyone who fears they have or will be exposed to it in the near future.
The HBV vaccine is even safe to administer to pregnant women.

Facts About Hepatitis B
- Two billion people, or one in three, have been infected with hepatitis B worldwide. Of these, about 260 million live with chronic hepatitis B.
- Each year about 900,000 people die from hepatitis B worldwide, and about 2,000 of these deaths occur in the United States.
- Hepatitis B is transmitted through blood and is 100 times more infectious than HIV. An estimated one billion infectious viruses are in one-fifth of a teaspoon of blood of an infected person, so exposure to even a minute amount, such as on a shared toothbrush can cause infection.
- Hepatitis B is sometimes referred to as the silent epidemic because most people who are infected do not experience any symptoms.
- Liver cancer is the fourth leading cause of cancer deaths throughout the world, behind lung, colorectal and stomach cancers.
- Almost half of liver cancers are caused by chronic infection with hepatitis B.
- The World Health Organization recommends the inclusion of hepatitis B vaccine in immunization programs of all countries in 2017, about 8 of 10 infants born throughout the world received three doses of hepatitis B vaccine.
Can Hepatitis B Be Cured Totally
As of now, there isnt any complete cure for Hepatitis B infection. However, there are several treatments and medications that can help manage symptoms and reduce the risk of long-term health complications.

Does The Hepatitis B Vaccine Have Side Effects
Some children will develop pain or soreness in the local area of the shot, and low-grade fever.
There is one extremely rare, but serious, side effect. About 1 out of every 600,000 doses of the hepatitis B vaccine will cause a severe allergic reaction, called anaphylaxis, with symptoms including swelling of the mouth, difficulty breathing, low blood pressure or shock. Anaphylaxis usually occurs within 15 minutes of receiving the vaccine. Although anaphylaxis can be treated, it is quite frightening. People should remain at the doctors office for about 15 minutes after getting the vaccine.
Although the hepatitis B vaccine is made in yeast cells, no one has ever been shown to be allergic to the yeast proteins contained in the hepatitis B vaccine .
How Is This Vaccine Given
This vaccine is given as an injection into a muscle. You will receive this injection in a doctor’s office or other clinic setting.
The hepatitis A and B vaccine is given in a series of 3 shots. The booster shots are given 1 month and 6 months after the first shot.
If you have a high risk of hepatitis infection, you may be given 3 shots within 30 days, and a fourth shot 12 months after the first.
Your individual booster schedule may be different from these guidelines. Follow your doctor’s instructions or the schedule recommended by the health department of the state you live in.

What Are The Contraindications Of The Hepatitis B Vaccine
In respect to this, what are contraindications for immunizations?
Conditions often mistaken for contraindications include upper respiratory tract infections, diarrhea, antibiotic use, previous local reactions, and recovery from an acute illness. Vaccines should be administered in these circumstances to avoid missed opportunities.
Secondly, is Hep B vaccine contraindicated in pregnancy? The following vaccines are considered safe to give to women who may be at risk of infection: Hepatitis B: Pregnant women who are at high risk for this disease and have tested negative for the virus can receive this vaccine. It is used to protect the mother and baby against infection both before and after delivery.
Also asked, who should not take hepatitis B vaccine?
All children aged < 19 years who have not been vaccinated previously. Susceptible sexual partners of hepatitis B-positive persons. Sexually active persons who are not in a long-term, mutually monogamous relationship
Which vaccine is contraindicated in convulsions?
It is known that infants and young children who have had febrile or non-febrile convulsions are more likely to have convulsions after pertussis vaccine. A family history of seizures is not associated with such convulsions, however.
Vaccines For Hepatitis A And B
Our immune system battles foreign invaders every day, such as when we get a cold virus. When this happens, we develop immunity to that specific virus. This means that our body will fight off the virus if it is ever exposed to it again.
The same protection happens with vaccines. However, the benefit of a vaccination is that you don’t have to go through being sick to enable your body to fight off disease.
Gregory Poland, MD, director of the Mayo Clinic’s Vaccine Research Group, explains that hepatitis vaccinations contain a small amount of the inactive virus. When you get a dose of the vaccine, he says, your immune cells respond by developing immunity against the virus. This immunity lasts over a long period of time.
“So if I get these two doses of hepatitis A vaccine, and then I get exposed 30 years from now, my body will remember that immunity to the vaccine and rapidly start producing antibodies again,” says Poland.
Due to the way hepatitis vaccinations are developed, it is impossible to contract the virus from the vaccine itself, according to Poland.
The hepatitis A vaccine is usually given in two shots and the hepatitis B vaccine is administered as a series of three shots. The most common side effects are redness, pain, and tenderness where the shots are given.
To get long-term protection from these viruses, it’s important to receive all the shots as scheduled. However, if you received one shot and never went back for the others, it’s not too late to catch up.

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.

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.
General Information About Vaccination Outside The Us
In developing countries, the pentavalent vaccine, a combination 5-in-one vaccine that protects against five diseases, diphtheria, pertussis, tetanus, Hib and hepatitis B, may be given to babies more than 6 weeks of age, and can be given up to 1 year of age. The first dose is given at 6 weeks, and the second and third doses are given at 10 and 14 weeks of age. The pentavalent vaccine may be made available free of charge with the support of GAVI, the vaccine alliance. Check the GAVI country hub to see the resources and immunizations that may be available:
For babies born to mothers with hepatitis B, waiting for the first dose of the pentavalent vaccine is too late and will NOT protect the baby from vertical or horizontal transmission of hepatitis B. Babies born to a mother with hepatitis B have a greater than 90% chance of developing chronic hepatitis B if they are not properly treated at birth.
WHO recommends the hepatitis B vaccine within 24 hours of birth for ALL babies. Plan ahead and inquire about the availability and cost of the monovalent , birth dose of the vaccine, as it is not a GAVI provided immunization. This is particularly important to women who are positive for hepatitis B.
If you are unsure of your hepatitis B status, please be sure your doctor tests you for hepatitis B!
*WHO does not recommend a birth dose of HBIG, which may not be available in all countries. Talk to your doctor if you have questions.
