Hepatitis B Vaccine Lasts How Long

The Hepatitis B Vaccine And Immunosuppressants

Hepatitis B Vaccine

If you are taking or about to start taking a medication that suppresses your immune response, let your healthcare provider know. Immunosuppressants may make certain vaccines less effective. Your healthcare provider may recommend that you get the hepatitis B vaccine at a particular time during your course of medication.

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.

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

What To Think About

If you are exposed to HBV before you have received all three shots in the vaccination series, a dose of hepatitis B immune globulin usually will prevent infection until the vaccine takes effect.

If you have already had hepatitis B and have developed protective antibodies to the virus, you do not need the vaccine because you have lifetime protection against the infection. If you are not sure whether you have had hepatitis B, you can be tested, or you can be vaccinated without testing. The vaccine is not harmful for you if you are already immune.

If you have chronic HBV infection, the vaccine will be ineffective, although it is not harmful.

The vaccine is safe for women who are pregnant or breastfeeding.

Who Is Allowed To Have The Vaccine

Recommended Childhood and Adolescent Immunization ScheduleUnited ...

The vaccination is routinely available to children as part of the NHS 6-in-1 vaccine schedule from birth at 8, 12 and 16 weeks of age.

Although the risk of infection is low in the UK, the virus persists for longer in children than it does adults so to avoid complications such as scarring and even liver cancer theyve given the vaccine.

Other high risk groups of people offered the vaccine include:

close family or sexual partners of someone with hepatitis B male and female sex workers people with any form of chronic liver disease people who inject drugs or have a partner who injects drugs babies born to infected mothers people who change their sexual partners frequently men who have sex with men anyone who receives regular blood transfusions or blood products, and their carers people with chronic kidney disease people who work somewhere that places them at risk of contact with blood or body fluids, such as nurses, prison staff, doctors, dentists and laboratory staff people travelling to high-risk countries prisoners families adopting or fostering children from high-risk countries

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.

Rare Side Effects After Immunisation

There is a very rare risk of a serious allergic reaction to any vaccine. This is why you are advised to stay at the clinic or medical surgery for at least 15 minutes following immunisation, in case further treatment is required.

If you think your child may be having a serious allergic reaction and you are no longer at the clinic where they were immunised, take them immediately to your doctor or to the nearest hospital, or call 000 for an ambulance.

Another rare side effect is the hypotonic-hyporesponsive episode . If they are experiencing HHE, a baby may be:

This may occur from one to 48 hours following vaccination. The whole episode may last from a few minutes to 36 hours.

If you think your child may be having an HHE episode, take them immediately to your doctor or to the nearest hospital.

Follow-up of children with HHE shows no long-term neurological or other side effects.

Babies And Children Can Develop Chronic Hbv

You may be wondering why the recommendations for the HBV vaccine start on the first day of life.

Adults who contract HBV will likely not experience long-term complications from hepatitis B. But the same is not the case for babies. As many as of babies who contract an HBV infection at birth from their mothers become chronically infected with HBV.

Children between the ages of 1 and 5 who get an HBV infection have a 25 percent of people who become chronically infected during childhood will develop liver cancer or cirrhosis. Thats why pediatricians want children to have immunity from HBV from the earliest possible age. Many babies and children exposed to HBV receive post-exposure prophylaxis, which decreases chance of infection.

If youre pregnant, youll most likely have a blood test to see if youre positive for hepatitis B. This allows doctors to find out if theres a chance that you could pass on the virus. These tests are highly sensitive and have a good accuracy rate, but they arent perfect. Additionally, a pregnant person may become infected between the time of the test and giving birth. The first dose of the vaccine given at birth lowers the risk of a newborn baby contracting hepatitis B.

Who Should Not Receive The Hepatitis B Vaccine

Hepatitis B Vaccine for Babies – Importance and Recommended Schedule

Talk to your healthcare provider before getting the hepatitis B vaccine if:

  • You have had a severe allergic reaction to the hepatitis B vaccine or any of its ingredients in the past.
  • You have had an allergic reaction to yeast in the past.
  • You are moderately or severely ill.
  • You are currently taking immunosuppressive medications.

In addition, pregnant people should not receive the Heplisav-B or PreHevbrio vaccines until more safety information is available.

What Is Hepatitis B

Hepatitis B is a highly infectious disease caused by the hepatitis B virus. It affects the liver and exists in two forms acute and chronic. The virus can be transmitted through direct contact with infected blood and other bodily fluids, as well as via sexual intercourse. It can also be transmitted from mother to child during pregnancy and childbirth.

Other ways to contract the virus include intravenous drug use, working in healthcare , tattooing, acupuncture, unprotected sex , and living with an infected individual. People with compromised immune systems and other chronic diseases are also at a higher risk of contracting the virus.

It is important to note that Hepatitis B cant be transmitted via holding hands, kissing, breastfeeding, or eating with the same utensils.

Commonly, the chronic variation of the disease shows no obvious symptoms, though people suffering from it may eventually develop liver cancer and cirrhosis. On the other hand, acute Hepatitis B takes between 30 and 180 days to show the first signs. The most common symptoms include a loss of appetite, fever, weakness, the yellowing of eye whites and skin, dark urine, fatigue, pain in muscles and joints, and abdominal discomfort.

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.

Response To Booster Dose

Because study participants in group 3 received a booster vaccine dose 8 years earlier , they did not receive a booster dose at 30 years. Study participants in groups 1 and 2 with anti-HBs levels < 10 mIU/mL received booster doses however, because group 2 participants had anti-HBs levels 10 mIU/mL at 22 years, we chose to focus on group 1 for booster dose response. In group 1, among 118 eligible participants, 96 who had anti-HBs levels < 10 mIU/mL received a booster dose of hepatitis B vaccine. The median age of the 85 persons from whom serum was obtained after the booster dose was 40 years 47 were male. Among these 85 persons tested 30 days after the booster dose, 75 responded with anti-HBs levels 10 mIU/mL the GMC was 150.4 mIU/mL .

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 dont know that they are infected, it is very hard to avoid the chance of getting infected with hepatitis B virus.

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.
