What Type Of Vaccine Is Hepatitis B

How To Get Vaccinated Against Hepatitis B

All babies in the UK born on or after 1 August 2017 are given 3 doses of hepatitis B-containing vaccine as part of the NHS routine vaccination schedule.

These doses are given at 8, 12 and 16 weeks of age.

Babies at high risk of developing hepatitis B infection from infected mothers are given extra doses of the hepatitis B vaccine at birth, 4 weeks and 1 year of age.

If you think you’re at risk and need the hepatitis B vaccine, ask your GP to vaccinate you, or visit any sexual health or genitourinary medicine clinic.

If your job places you at risk of hepatitis B infection, it’s your employer’s responsibility to arrange vaccination for you, rather than your GP. Contact your occupational health department.

Enhancing Healthcare Team Outcomes

The interprofessional health care team faces many challenges when vaccinating patients for hepatitis B. While few medical interventions have as significant an impact on health as vaccinations, and the hepatitis B vaccination is generally safe, lack of knowledge about the vaccine by healthcare team members and patient concern about adverse events can decrease coverage. Challenges on knowledge of the vaccine for healthcare team members include staying current on evolving recommendations for whom the vaccine is indicated. All team members can increase the vaccination rate of their patients by encouraging all staff to become trained in the assessment of vaccination histories and any pertinent staff in the administration of the vaccine. Protecting the time available for the team to do this is an essential component of this strategy. All patients should receive education on the benefits of vaccination, including its herd immunity effect, the generally safe side effect profile, and the relatively few contraindications. A presumption of acceptance may be effective with most patients. The hesitant parent and patient who does not respond to this can pose a challenge in vaccination. Motivational interviewing techniques have shown to be effective with these hesitant patients.

Persons With Chronic Diseases

Refer to Immunization of Persons with Chronic Diseases in Part 3 for additional general information about vaccination of people with chronic diseases.

Chronic renal disease and patients on dialysis

People with chronic renal disease may respond sub-optimally to HB vaccine and experience more rapid decline of anti-HBs titres, and are therefore recommended immunization with a higher vaccine dose. Individuals undergoing chronic dialysis are also at increased risk for HB infection. In people with chronic renal disease anti-HBs titre should be evaluated annually and booster doses using a higher vaccine dose should be given as necessary.

Neurologic disorders

People with conditions such as autism spectrum disorders or demyelinating disorders should receive all routinely recommended immunizations, including HB-containing vaccine.

Chronic liver disease

HB immunization is recommended for non-immune persons with chronic liver disease, including those infected with hepatitis C, because they are at risk of more severe disease if infection occurs. Vaccination should be completed early in the course of the disease, as the immune response to vaccine is suboptimal in advanced liver disease. Post-immunization serologic testing may be used to confirm vaccine response.

Non-malignant hematologic disorders

Persons with bleeding disorders and other people receiving repeated infusions of blood or blood products are considered to be at higher risk of contracting HB and should be offered HB vaccine.

Active Vaccination To Prevent Infection

Hepatitis B vaccination is available for preexposure and postexposure prophylaxis and provides long-term protection. Hepatitis B vaccines are produced recombinantly in yeast cell systems. The vaccines contain noninfectious HBsAg , a small amount of yeast protein, and aluminum hydroxide as an adjuvant. Pediatric formulations contain trace or no thimerosal. Administration is via the intramuscular route. Adverse effects are generally mild and mainly consist of local tenderness and low-grade fever. After a vaccine series, more than 95% seroconversion is achieved, which results in > 90% efficacy. Studies are ongoing to determine length of immunity, but it is at least 20 years.

Two hepatitis B single antigen vaccines are available in the United States: Recombivax from Merck & Co. and Engerix-B from GlaxoSmithKline. Both vaccines come in doses for pediatric and adult populations. High-dose vaccines are available for adult hemodialysis and immunocompromised patients. Both vaccines are given in a three-dose series and are generally interchangeable. A fourth dose may be given if a birth dose was administered. The birth dose must be a single antigen formulation.

Booster doses of hepatitis B vaccine beyond the initial series are generally not recommended. The long incubation period of hepatitis B theoretically allows for the development of a protective anamnestic immune response after exposure.

Fabrizio Fabrizi MD, Paul Martin MD, in, 2017

When To Delay Or Avoid Hepb Immunization

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

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.

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.

Don’t Miss: Hepatitis B Is Much More Easily Transmitted Than Hiv

When The Hepatitis B Virus Becomes Chronic It Can Increase The Risk Of Developing:

• Lifelong infection
• Cirrhosis, or scarring, of the liver

The risk of the infection becoming chronic increases the younger people are when they are infected with hepatitis B, particularly newborns or children under 5.

Although there is no cure for hepatitis B, getting vaccinated is the best way to prevent it.

Hepatitis B Vaccination In Pregnancy

Hepatitis B infection in pregnant women may result in severe disease for the mother and chronic infection for the baby.

This is why the hepatitis B vaccine is recommended for pregnant women who are in a high-risk category.

There’s no evidence of any risk from vaccinating pregnant or breastfeeding women against hepatitis B.

And, as it’s an inactivated vaccine, the risk to the unborn baby is likely to be negligible .

Common And Local Adverse Events

HB vaccine

HB vaccine is well tolerated. Reactions are generally mild and transient, and include: irritability, headache, fatigue and injection site reactions in 10% or more of recipients.

HAHB vaccine

There is no increase in adverse events when HAHB vaccine is compared with HA vaccine given alone or concomitantly with HB vaccine at a different injection site. When the adult formulation of HAHB vaccine is given to children in the 2 dose schedule, there is no increase in adverse events compared with those occurring after administration of the pediatric formulation of HAHB vaccine.

DTaP-HB-IPV-Hib vaccine

Reactions are usually mild and transient, and include fever, irritability, restlessness and injection site reactions .

Detection Of Antiviral Resistance

National and international surveillance is performed by the CDC to determine effectiveness of the current FDA-approved antiviral flu drugs. Public health officials use this information to make current recommendations about the use of flu antiviral medications. further recommends in-depth epidemiological investigations to control potential transmission of the resistant virus and prevent future progression. As novel treatments and detection techniques to antiviral resistance are enhanced so can the establishment of strategies to combat the inevitable emergence of antiviral resistance.

Two versions of hepatitis B vaccine are available. One, called Heplisav-B, contains a novel adjuvant that was not present in previous versions used by adults . Some people did not respond to the older version hepatitis B vaccine. In fact, in a group of adults younger than 40 years of age who received two doses of the older version vaccine 75 of 100 were protected. Following the third dose, this number increased to 90 of 100. However, people older than 40 years of age were less likely to respond to the vaccine with increasing age. On the other hand, 90 to 100 of 100 adults 18 years of age and older respond to Heplisav-B, which was approved for use in 2018.

About 5-10 of every 100 children and adults younger than 40 years of age do not respond to the third dose of the hepatitis B vaccine. Some of these people will be recommended to get vaccinated again. About 5 of 100 people will still not respond after getting all recommended doses of both series. Note that children younger than 18 years of age cannot get Heplisav-B.

If the people who do not respond to vaccination are determined not to have chronic hepatitis B, they will be reliant on taking precautions to reduce the chance of exposure and relying on those around them for protection. In other words, these people will be reliant on herd immunity.

How Is Hepatitis Contracted

There are various ways of contracting hepatitis, depending on the type. Contracting a viral form of hepatitis depends on the mode of transmission, which the table above shows.

A person may sometimes contract hepatitis nonvirally. In autoimmune hepatitis, the immune system attacks the liver cells. Ingesting substances that contain toxins, such as alcohol, can also induce some types of hepatitis.

A doctor may use a blood test to diagnose viral hepatitis.

A healthcare professional will check a persons blood for:

• HAV-specific immunoglobulin G antibodies to diagnose HAV
• the surface antigen HBsAg to diagnose HBV
• anti-HCV antibodies to diagnose HCV
• high immunoglobulin G and anti-HDV immunoglobulin M levels to diagnose HDV
• virusspecific IgM antibodies to identify HEV

To autoimmune hepatitis, a doctor may consider:

Who Should Get The Hbv Vaccine

The Centers for Disease Control and Prevention recommends that all children and adults up to age 59 should receive the hepatitis B vaccine.

Infants should get their first hepatitis B vaccine within 24 hours of birth and complete their doses by age 6 to 18 months.

All unvaccinated children and adults through age 59 should receive the vaccine. Also, unvaccinated adults over the age 60 who are at risk of hepatitis B should get the vaccine.

Adults over age 60 who are not at risk of hepatitis B may also choose to get the shot.

Several types of the HBV vaccine are also safe to administer to pregnant women.

• people who have had more than one sex partner in the last 6 months
• men who have sex with men
• people seeking treatment for a sexually transmitted infection
• people whose partners or household members have hepatitis B
• people who inject drugs
• people who live or work in care facilities
• people who are on dialysis
• travelers to countries where hepatitis B is common
• people with chronic liver disease, HIV, or hepatitis C
• people who are in jail or prison

People who have diabetes should talk with a healthcare professional about their risk for contracting hepatitis B.
