Hepatitis B Vaccine In Newborns

Side Effects Of Hepatitis B Vaccines

Why Do Newborns Get the Hepatitis B Vaccine?

Immunisations containing components to protect against hepatitis B are effective and safe, although all medication can have unwanted side effects.

Side effects from the vaccine are uncommon and usually mild, but may include:

  • Localised pain, redness and swelling at the injection site.
  • Low-grade temperature .
  • In children being unsettled, irritable, tearful, generally unhappy, drowsy and tired.
  • Occasionally, an injection-site lump that may last many weeks, but for which treatment is not needed.

Who Should Not Get The Hepatitis B Vaccine

Speak with your health care provider if your child has had a life-threatening reaction to a previous dose of hepatitis B vaccine, or any component of the vaccine, including yeast or to latex.

There is no need to delay getting immunized because of a cold or other mild illness.

However, if you have concerns speak with your health care provider.

Possible Risks And Side Effects

The hepatitis B vaccine is extremely safe, and most infants who get the vaccine have no issues. But as with any medicationincluding vaccinesthere is a chance of side effects.

For those who do experience side effects, they are usually mild including soreness at the injection site and possibly a low-grade fever. Reports of serious side effects from the vaccination or allergic reactions are extremely rare. According to the AAP, commonly reported mild adverse reactions from the vaccine in all people include swelling , fever , headache , erythema or redness , and pain .

Yet, it’s normal for parents to worry about the vaccine with so much conflicting information out there. For instance, some parents worry that vaccinations like hepatitis B will increase the likelihood that their child will develop neurological issues like autism, multiple sclerosis, and attention-deficit/hyperactivity disorder . But there is no conclusive evidence that this can occur.

What’s more, the AAP points out that the safety of the hepatitis B vaccine has been studied extensively and that there is no evidence of a causal association between the vaccine and neonatal sepsis or death.

Instead, focus on comforting your baby while also supporting your baby’s doctor and nurses. It can help to provide some sort of distraction while the vaccine is being administered in addition to comforting measures after.

How Do You Catch Hepatitis B Virus

Blood from a person infected with hepatitis B virus is heavily contaminated with the virus. As a result, contact with blood is the most likely way to catch hepatitis B. Even casual contact with the blood of someone who is infected can cause infection.

Healthcare workers are at high risk of catching the disease, as are intravenous drug users and newborns of mothers infected with the virus. Sexual contact can also expose people to infection. The virus is also present in low levels in saliva.

Why Should I Vaccinate My Newborn Child If I Know That I Am Not Infected With Hepatitis B Virus

Hepatitis B Vaccine for Newborns, Why Its Important

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 the 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.

Prevalence Of Hbv Markers

We analysed 21 studies reporting on HBsAg prevalence in populations exposed to universal vaccination compared with those given no vaccination . The prevalence in the universally vaccinated cohorts ranged from 0.3%27 to 8.5%33 . The prevalence of HBsAg in the corresponding no vaccination cohorts were substantially higher, ranging from 0.6%48 to 16.3%34 . All except one study45 reported a decrease in HBsAg prevalence the combined RP in vaccinated populations was 0.24 . Among 15 studies that reported on HBsAg in a targeted vaccination cohort , prevalences ranged from 0.6%41 to 11.4%31 , compared with a range of 3.5%38 to 16.3%34 in the corresponding no vaccination cohorts, leading to a combined RP of 0.32 . Highly significant statistical heterogeneity between studies was found in the meta-analyses of HBsAg prevalence in studies comparing both universal and targeted vaccination with unvaccinated cohorts . We therefore used random-effects models to estimate combined RPs and CIs.

Why Should My Baby Get The Hepatitis B Shot

  • Protects your child from against hepatitis B, a potentially serious disease.
  • Protects other people from the disease because children with hepatitis B usually dont have symptoms, but they may pass the disease to others without anyone knowing they were infected.
  • Prevents your child from developing liver disease and cancer from hepatitis B.
  • Keeps your child from missing school or child care and you from missing work.

What Is Hepatitis B

Hepatitis B is a contagious liver disease caused by the hepatitis B virus. When a person is first infected with the virus, he or she can develop an acute infection. Acute hepatitis B refers to the first 6 months after someone is infected with the hepatitis B virus. This infection can range from a very mild illness with few or no symptoms to a serious condition requiring hospitalization. Some people are able to fight the infection and clear the virus.

For others, the infection remains and is chronic, or lifelong. Chronic hepatitis B refers to the infection when it remains active instead of getting better after 6 months. Over time, the infection can cause serious health problems, and even liver cancer.

When To Delay Or Avoid Hepb Immunization

Hepatitis B Vaccine for Babies – Importance and Recommended Schedule

Doctors delay giving the vaccine to babies who weigh less than 4 pounds, 7 ounces at birth whose mothers do not have the virus in their blood. The baby will get the first dose at 1 month of age or when the baby is discharged from the hospital.

The vaccine is not recommended if your child:

  • is currently sick, although simple colds or other minor illnesses should not prevent immunization
  • had a serious allergic reaction after an earlier dose of the vaccine or is allergic to baker’s yeast

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.

Unprotected Babies: Hepatitis B Vaccine At Birth Saves Lives

On October 17, 2001, the Advisory Committee on Immunization Practices voted to recommend a birth dose of hepatitis B vaccine for all U. S. infants.

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.

Us Children And Adult Hepatitis B Vaccine Schedules

Hepatitis B Vaccination of Infants, Children, and Adolescents
*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.

A Look At Each Vaccine: Hepatitis B Vaccine

The hepatitis B vaccine is given to prevent the severe liver disease that can develop when children or adults are infected with hepatitis B virus. The hepatitis B vaccine is given as a series of three shots. The first dose is given within 24 hours of birth. The second dose is given one to two months after the first dose, and the third dose is given between 6 months and 18 months of age. The vaccine is also recommended for those up to 60 years of age who have not previously received it and those 60 years and older who are at increased risk or who simply want the protection afforded by vaccination.

Important Information About Vaccine And Hepatitis B Immunoglobulin Shot Administration

Where available, the hepatitis B birth-dose and HBIG should be administered within 24 hours of birth in order to prevent the transmission of hepatitis B from mother to child. It is very important that the shots be given in opposite limbs, to ensure the highest effectiveness. Please see chart above for more information.

Accelerated 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.

In some instances, it may be necessary to vaccinate within a short period of time to ensure protection before travel. There are accelerated schedules to provide the highest level of protection over a short period of time. Individuals who need an accelerated schedule must have a booster dose at 1 year to ensure long-term protection. Note that the 2-dose Heplisav-B vaccine will also ensure maximum protection over a 1-month period without the need for a booster dose at 1 year.

4-Dose Vaccine Series for Children and Adults

Engerix-B is a 3-dose vaccine that can be given on an accelerated, four-dose schedule, with 3 shots administered within 2 months, and a booster dose at 1 year to provide maximum long-term protection.

4-Dose Combination Hepatitis A and B Vaccine Series

Twinrix is a 4-dose vaccine that can be given on an accelerated schedule to provide protection against hepatitis A and B. Three doses are administered within 1 month, followed by a booster shot at 1 year. This is a common choice of vaccine for those travelling on short-notice outside the U.S. It is important to complete the booster dose at 1 year, to ensure long-term protection.

Who Should Receive The Hepatitis B Vaccine

For most people, the hepatitis B vaccine is safe and effective. About 90% of people who receive three vaccine doses are protected against hepatitis B for over 30 years.

The CDC’s Advisory Committee on Immunization Practices recommends the hepatitis B vaccine for the following groups:

  • All babies, starting just after birth
  • Children and adolescents under 19 years old
  • Adults ages 1959 who have not previously completed vaccination
  • Adults ages 60 and over with a high risk of contracting HBV

Adults ages 60 and over who do not have any hepatitis B risk factors can receive the hepatitis B vaccine, but it is optional.

Hepatitis B spreads when the bodily fluids of an infected person enter another person’s body. Sexual contact is one way it can be spread. A person with HBV can spread it to their baby during childbirth. Other ways in which HBV may be transmitted include:

  • Sharing medical equipment, whether at home or in a hospital setting, with a person who has an HBV infection
  • Sharing syringes with a person who has hepatitis B, such as during injection drug use or at-home piercing or tattooing
  • Sharing personal items, such as razors or toothbrushes, with someone who has hepatitis B
  • Coming into contact with the sores or blood of a person who has hepatitis B

Hepatitis B Vaccination Schedule For Children And Infants

The Centers for Disease Control and Prevention recommends that babies and children receive three 0.5 milliliter doses of either Engerix-B or Recombivax HB, starting just after birth.

The current recommended hepatitis B vaccine schedule for children and infants is as follows:

Hepatitis B Vaccination Schedule for Infants and Children
Hepatitis B Vaccine Dose
3618 months old

If your child is undergoing hemodialysis, your healthcare provider may recommend that they receive additional doses of the HBV vaccine.

How Hepatitis B Spreads

Because hepatitis B is transmitted from person to person through blood and other body fluids, it is a sexually transmitted infection , but people can get the virus from casual contact with others as well, like sharing a razor or using the wrong toothbrush. Even a bite from an infected child can spread the infection.

Newborns are at high risk of getting hepatitis B through childbirth from mothers who are already infected with the virus. What’s more, they can get the virus regardless of whether they are born vaginally or through a c-section. Unfortunately, even children born to a mother who doesn’t have hepatitis B are at risk because the infection spreads so easily from person to person.

It’s impossible to tell if someone has hepatitis B just by looking at them. In fact, most people with hepatitis B have no symptoms, don’t feel sick, and are unaware that they even have the illness. Consequently, they can spread the virus to other people without even knowing it.

The only way to know if someone has hepatitis B is through a blood test. And once people find out that they have it, it’s often in the advanced stages. Even if it is caught early, there is very little that can be done medically for people with the disease. In fact, the younger a person is when they become infected, the more likely they are to have lifelong liver problems.
