How Often Should You Get Hepatitis B Vaccine

Who Should Not Receive Hepatitis A Vaccine

Hepatitis B Vaccine: Routine and Catch-up Schedule

There are a very few situations where the hepatitis A vaccine is not recommended. They include:

  • If you have an illness causing a high temperature. In this situation, it is best to postpone vaccination until after you have fully recovered from the illness.
  • If you have had an allergic reaction to the vaccine or to any of its components in the past.
  • One type of vaccine should not be given to anyone who is known to be allergic to eggs.
  • Children under the age of 1 year. However, the risk of hepatitis A in children under the age of 1 year is very low. The hepatitis A vaccine is not licensed for this age group.

The vaccine may be given if you are pregnant or breastfeeding and vaccination against hepatitis A is thought to be necessary.

Complications Of Hepatitis B In Infants And Children

Mothers who are infected with hepatitis B can pass the virus to their children either through the womb or at the time of birth. Hepatitis B virus can also be spread through exposure of broken skin or mucous membranes to the blood or other body fluids of an infected person.

If newborn babies are quickly immunised with 2 vaccines, they can be protected from getting hepatitis B.

Many people who are infected with hepatitis B have no symptoms. Babies and children who are infected with hepatitis B are less likely than adults to have symptoms of infection, but are more likely to develop chronic hepatitis B.

A child who contracts chronic hepatitis B has an increased risk of developing liver disease and cancer later in life. A small proportion of adults who become infected with the hepatitis B virus develop a long-term hepatitis B infection.

Hepatitis B virus is transmitted between people by direct blood-to-blood contact or semen and vaginal fluid of an infected person and is also an occupational risk for individuals with potential for exposure to human blood, body fluids, tissues, and cells.

Modes of transmission are the same as those for the human immunodeficiency virus , but the Hepatitis B virus is 50 to 100 times more infectious. Unlike HIV, the Hepatitis B virus can survive outside the body for at least 7 days. During this time, the virus can still cause infection if it enters the body of a person who is not protected by the vaccine.

A safe and effective vaccine against Hepatitis B has been available since 1982 and is the first vaccine against a major human cancer.

If a protective antibody response develops after vaccination, vaccine recipients are virtually 100% protected against clinical illness. After administration of the 3-dose Hepatitis B vaccination series, more than 90% of healthy adults age 40 years or younger develop adequate antibody responses. After age 40, the proportion of persons who have a protective antibody response to vaccination begins to decline below 90%, and by age 60 years, protective levels of antibody develop in only 75% of vaccinated persons.

Hepatitis B vaccination is strongly recommended for employees who have occupational exposure to bloodborne pathogens .

Who Should Be Immunised Against Hepatitis A

Travellers to countries outside Western Europe, North America and Australasia should consider being immunised. The highest-risk areas include the Indian subcontinent , Africa, parts of the Far East , South and Central America and the Middle East. Vaccination is generally recommended for anyone over the age of 1 year. Your doctor or practice nurse can advise if you should be immunised against hepatitis A for your travel destination.

You can find out if immunisation against hepatitis A is recommended for any countries you are planning to visit from the NHS website Fitfortravel.

Close contacts of someone with hepatitis A. Occasional outbreaks of hepatitis A occur in the UK within families or in institutions. Close contacts of someone found to have hepatitis A infection may be offered vaccination. This only happens rarely. The most important measure for anybody with hepatitis A is good personal hygiene. In particular, washing hands after going to the toilet or before eating.

People with chronic liver disease. If you have a persistent liver disease it is suggested that you have the hepatitis A vaccine. Hepatitis A infection is not more common in those with chronic liver disease but, if infection does occur, it can cause a more serious illness.

People exposed to hepatitis A at work. For example, laboratory workers who are exposed to hepatitis A during their work and sewage workers are advised to be immunised against hepatitis A.

Why Is The Hepb Vaccine Recommended

Know The ABC

People who dont know they’re infected can spread the hepatitis B virus. So it cant be avoided just by being careful. That’s why health experts recommend that all babies get the vaccine right from birth.

The HepB injection usually creates long-term immunity. Most infants who get the HepB series are protected from hepatitis B infection beyond childhood, into their adult years.

Eliminating the risk of infection also decreases risk for cirrhosis of the liver, chronic liver disease, and liver cancer.

Immunization Nurse

Treatment And Manifestation Of Hepatitis A And B

Hepatitis A has an incubation time of two to six weeks. Hepatitis B only manifests after two to six months. Often patients with hepatitis A and B infection have moderate to no signs of the infection.

In persons who show symptoms, they will get flu-like symptoms, which will occur about three to ten days before symptoms of the liver develop.

Thereafter, the urine will darken, and jaundice may grow. With jaundice, the skin and the whites of a person’s eyes have a yellow hue. The inflamed liver cannot conduct its normal biochemical processes, so a material called bilirubin increases in the body.

Typically, you tend to feel healthy when you have jaundice, even though you keep looking worse.

In hepatitis A the jaundice stage only lasts for about one week. After that, you’ll continue to heal and usually feel like your usual self within a month. You are immune for life after recovering from hepatitis A.

In hepatitis B, the jaundice stage is about two weeks.

Emergency Hepatitis B Vaccination

If you have 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.

Don’t Miss: What Does Hepatitis Do To The Body

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.

Hepatitis B Vaccine On The Nhs

A hepatitis B-containing vaccine is provided for all babies born in the UK on or after 1 August 2017. This is given as part of the 6-in-1 vaccine.

Hospitals, GP surgeries and sexual health or GUM clinics usually provide the hepatitis B vaccination free of charge for anyone at risk of infection.

GPs are not obliged to provide the hepatitis B vaccine on the NHS if you’re not thought to be at risk.

GPs may charge for the hepatitis B vaccine if you want it as a travel vaccine, or they may refer you to a travel clinic for a private vaccination. The current cost of the vaccine is around £50 a dose.

What Is Hepatitis A

Hepatitis A is an illness caused by the hepatitis A virus. The virus mainly causes inflammation of the liver. Symptoms include:

  • Generally feeling unwell.
  • Yellowing of your skin or the whites of your eyes .
  • Sometimes, being sick .
  • A raised temperature .

However, some people who are infected do not develop any symptoms . The illness is not usually serious and full recovery is usual but the symptoms can be quite unpleasant for a while. The hepatitis A virus is passed out in the stools of infected people and infection is usually spread by eating dirty food or drink.

Hepatitis A infection can occur in the UK but it is more common in countries where there is poor sanitation or where disposal of sewage is poor. In the UK, most cases of hepatitis A are seen in people who have recently returned after travelling to such countries. If you catch hepatitis A, the illness is not usually serious but it may ruin a holiday or business trip. See the separate leaflet called Hepatitis A for more details.

This leaflet is just about vaccination to help prevent hepatitis A infection.

People With Chronic Hepatitis B

Vaccine (Shot) for Hepatitis A

The vaccine does not affect people with chronic hepatitis B virus infection there are no therapeutic benefits or associated adverse events. The vaccine is also safe in people who are already immune to hepatitis B through past natural infection, but it offers no additional benefit.

Hepatitis B is an infection caused by hepatitis B virus. It affects the liver.

Immunisation Against Hepatitis B For People At Risk

In Victoria free hepatitis B vaccine is provided for people who are at increased risk, including:

  • Men who have sex with men.
  • People living with HIV.
  • People living with hepatitis C.
  • Prisoners.
  • People no longer in a custodial setting who commenced, but did not complete, a free vaccine course while in custody.
  • Aboriginal and Torres Strait Islander people.
  • People born in priority hepatitis B endemic countries who arrived in Australia in the last 10 years priority countries include China, Philippines, Malaysia, Vietnam, Afghanistan, Thailand, South Korea, Myanmar , Indonesia, Singapore, Hong Kong, Taiwan and Cambodia.
  • Vulnerable citizens people who have experienced hardship that prevented them from accessing the vaccine earlier. Vulnerable citizens are vaccinated based on an individual assessment by an immunisation provider.

Immunisation is also recommended, but not free, for people who are at increased risk including:

If you think you have been exposed to hepatitis B, see a doctor immediately. Your doctor can give you treatment that, in some instances, can greatly reduce your risk of infection with hepatitis B.

Remember that being immunised against hepatitis B does not protect you against HIV, hepatitis C or other diseases spread by blood or bodily fluids. It is important that you take precautions to make sure you are not exposed to these diseases.

Twinrix: The Vaccine For Hepatitis A And B

Both hepatitis A and B are identified by obtaining a blood sample, which you submit to a laboratory test. This test decides whether you have antibodies in the blood unique to those viruses. If the result is positive, you have been subjected to either hepatitis A or B.

To check whether anyone has hepatitis B, the test will see whether the individual has certain hepatitis B antigen levels.

Who Should Get Immunised Against Hepatitis B

Anyone who wants to protect themselves against hepatitis B can talk to their doctor about getting immunised.

Hepatitis B immunisation is recommended for:

People under 20 years old, refugees and other humanitarian entrants of any age, can get hepatitis B vaccines for free under the NIP. This is if they did not receive the vaccines in childhood. This is called catch-up vaccination.

Safety Of Hepatitis Vaccines

Chronic Hepatitis B: What to do after diagnosis (1/3)

Serological Testing After Hepatitis B Vaccination

It is recommended that levels of hepatitis B surface antigen in infants born to mothers with chronic hepatitis B are measured 312 months after they complete the infant vaccine course. Do not test the infant before 9 months of age, to avoid detecting anti-HBs

Post-vaccination serological testing is recommended 48 weeks after completing the vaccine course for:

  • people at significant occupational risk, such as healthcare workers whose work involves frequent exposure to human tissue, blood or body fluids
  • people at risk of severe or complicated hepatitis B, such as people who are immunocompromised and people with pre-existing liver disease not related to hepatitis B
  • people who may respond poorly to hepatitis B vaccination, such as haemodialysis patients and people with bleeding disorders who received the vaccine subcutaneously
  • close contacts of people who are infected with hepatitis B virus, including sexual partners, household contacts and household-like contacts22

If serological testing 48 weeks after the vaccine course shows levels of antibody to hepatitis B surface antigen of < 10 mIU per mL, check the person for acute or chronic hepatitis B virus infection by testing for serological markers, including antibodies to anti-HBs and hepatitis B core antigen.

After the booster dose, check for anti-HBs

A non-responder is a person who:

    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

    Vaccine For Hepatitis B

    Why do newborns need the hepatitis B vaccine?

    Hepatitis B Vaccine

    It takes only a few shots to protect yourself and your loved ones against hepatitis B for a lifetime.

    The hepatitis B vaccine is a safe and effective vaccine that is recommended for all infants at birth and for children up to 18 years. The hepatitis B vaccine is also recommended for adults living with diabetes and those at high risk for infection due to their jobs, lifestyle, living situations, or country of birth. Since everyone is at some risk, all adults should seriously consider getting the hepatitis B vaccine for a lifetime protection against a preventable chronic liver disease.

    The hepatitis B vaccine is also known as the first anti-cancer vaccine because it prevents hepatitis B, the leading cause of liver cancer worldwide.

    You cannot get hepatitis B from the vaccine. All hepatitis B vaccines that have been used since 1986 are made synthetically meaning the hepatitis B vaccines do not contain any blood products. Learn more.

    If you have a current HBV infection or have recovered from a past HBV infection, the hepatitis B vaccine series will not benefit you or clear the virus. However, the vaccine can provide a lifetime of protection for loved ones who do not have hepatitis B and get the vaccine as soon as possible. Testing is the only way to know if you or your loved ones have a current infection or have recovered from a past infection.
