How Long Does Hepatitis B Vaccine Last In The Body

Are There Any Side Effects To Twinrix

Living with Hepatitis B

Like any drug, the Twinrix vaccine can trigger side effects, but the chance of severe side effects is exceptionally low.

Very Common side effects felt in more than 10% of people receiving the vaccine are:

  • Headache
  • Pain and redness at the injection site

Common side effects felt between 1% and 10% of people receiving the vaccine are:

  • Diarrhea
  • Nerve disorders

Very rare in less than 0.01% of people receiving the vaccine are hives.

Still, you should call your doctor or hospital if you have critical or unusual reactions after receiving the vaccine.

Eating Diet And Nutrition For Hepatitis B

If you have hepatitis B, you should eat a balanced, healthy diet. Obesity can increase the chance of nonalcoholic fatty liver disease , and NAFLD can increase liver damage in people who have hepatitis B. Talk with your doctor about healthy eating and maintaining a healthy weight.

You should also avoid alcohol because it can cause more liver damage.

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.

What Are The Risk Factors For Getting Hepatitis B

Due to the way that hepatitis B spreads, people most at risk for getting infected include:

  • Children whose mothers have been infected with hepatitis B.
  • Children who have been adopted from countries with high rates of hepatitis B infection.
  • People who have unprotected sex and/or have been diagnosed with a sexually transmitted infection.
  • People who live with or work in an institutional setting, such as prisons or group homes.
  • Healthcare providers and first responders.
  • People who share needles or syringes.
  • People who live in close quarters with a person with chronic hepatitis B infection.
  • People who are on dialysis.

How Is Hepatitis B Spread

Chronic hepatitis C: Symptoms, causes, and treatment

You can become infected with hepatitis B through exposure to blood, semen and other bodily fluids of an infected person. You can get the infection by:

  • Having unprotected sex.
  • Sharing or using dirty needles for drug use, tattoos or piercing.
  • Sharing everyday items that may contain body fluids, including razors, toothbrushes, jewelry for piercings and nail clippers.
  • Being treated medically by someone who does not use sterile instruments.
  • Being bitten by someone with the infection.
  • Being born to a pregnant woman with the infection.

Hepatitis B is not spread by:

  • Kissing on the cheek or lips.
  • Coughing or sneezing.
  • Hugging, shaking hands or holding hands.
  • Eating food that someone with the infection has prepared.
  • Breastfeeding.

Can Hepatitis B Be Prevented

The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.

The disease has also been more widely prevented thanks to:

  • Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
  • Safer blood injection practices, using clean needles.
  • Safe-sex practices.

You can help prevent hepatitis B infections by:

  • Practicing safe sex .
  • Never sharing personal care items like toothbrushes or razors.
  • Getting tattoos or piercings only at shops that employ safe hygiene practices.
  • Not sharing needles to use drugs.
  • Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.

Alcohol And Other Toxins

Excessive alcohol consumption can cause liver damage and inflammation. This is sometimes referred to as alcoholic hepatitis. The alcohol directly injures the cells of your liver. Over time, it can cause permanent damage and lead to liver failure and cirrhosis, a thickening and scarring of the liver.

Other toxic causes of hepatitis include overuse or overdose of medications and exposure to poisons.

What Causes Hepatitis B

The hepatitis B virus causes hepatitis B. The hepatitis B virus spreads through contact with an infected persons blood, semen, or other body fluids. Contact can occur by

  • being born to a mother with hepatitis B
  • having unprotected sex with an infected person
  • sharing drug needles or other drug materials with an infected person
  • getting an accidental stick with a needle that was used on an infected person
  • being tattooed or pierced with tools that were used on an infected person and werent properly sterilized, or cleaned in a way that destroys all viruses and other microbes
  • having contact with the blood or open sores of an infected person
  • using an infected persons razor, toothbrush, or nail clippers

You cant get hepatitis B from

  • being coughed on or sneezed on by an infected person
  • drinking unclean water or untreated water that has not been boiled
  • eating food that is unclean or has not been properly cooked
  • hugging an infected person
  • shaking hands or holding hands with an infected person
  • sharing spoons, forks, and other eating utensils
  • sitting next to an infected person

Mothers who have hepatitis B can safely breastfeed their babies. If a baby receives hepatitis B immune globulin and starts receiving the hepatitis B vaccine to prevent hepatitis B infection shortly after birth, hepatitis B is unlikely to spread from mother to child through breastfeeding.15

Causes Of Hepatitis A

Hepatitis B vaccine for Grade 7 Students

Hepatitis A is caused by a virus. The virus can survive for several hours outside the body but persists on the hands and in food for even longer. It is resistant to heating and freezing.

The virus is spread when it enters the mouth, which can happen when hands, foods or other items are contaminated with the faeces of a person with hepatitis A. The disease can also be spread sexually by oral or anal contact.

A person with hepatitis A is infectious from 2 weeks before they show symptoms to one week after they become jaundiced .

If an infected person has no jaundice, they may pass on the virus until 2 weeks after they first have symptoms . Caution is advised beyond this period as the virus can be shed in stools for longer periods.

Will My Immunization Be Recorded

Your immunization records are registered in a computerized network known as the Immunization Records and Yellow Cards. While this one is specific to Ontario, each province has their own.

They can use information obtained in these databases to:

  • Maintain immunization data
  • Inform you whether or when you or your family members need an immunization
  • Track how well vaccinations perform to prevent vaccine-preventable infections

You can also share your immunization history with health care providers for the provision of social health services to aid with assessment and treatment and monitor the spread of infectious illnesses.

Liver Anatomy And Function

Main Function of the Liver

The liver is an essential organ that has many functions in the body. The liver plays an important role in detoxifying the body by converting ammonia, a byproduct of metabolism in the body, into urea that is excreted in the urine by the kidneys. The liver also breaks down medications and drugs, including alcohol, and is responsible for breaking down insulin and other hormones in the body. The liver also stores vitamins and chemicals that the body requires as building blocks.

Many different disease processes can occur in the liver, including infections such as hepatitis, cirrhosis , cancers, and damage by medications or toxins.

Symptoms of liver disease can include:

  • Jaundice

Outlook For Hepatitis B

The vast majority of people infected with hepatitis B in adulthood are able to fight off the virus and fully recover within 1 to 3 months.

Most will then be immune to the infection for life.

Babies and children with hepatitis B are more likely to develop a chronic infection.

Chronic hepatitis B affects around:

  • 90% of babies with hepatitis B
  • 20% of older children with hepatitis B
  • 5% of adults with hepatitis B

Although treatment can help, there’s a risk that people with chronic hepatitis B could eventually develop life-threatening problems, such as scarring of the liver or liver cancer.

What Is The Outlook For People With Hepatitis B

Chronic Hepatitis B Infection

The outlook for people with HBV is better now than ever before. You are certainly able to live a full life and help yourself stay healthy. You should make sure to have regular check-ups with a healthcare provider who is qualified to treat hepatitis B, possibly a liver doctor.

Make sure you are vaccinated against hepatitis A. Check with your healthcare provider or pharmacist before taking other medications or over-the-counter products, including supplements and natural products. These could interfere with your medication or damage your liver. For instance, taking acetaminophen in large doses may harm your liver.

Follow the usual guidelines for living a healthy life:

  • Eat nutritious foods, choosing from a variety of vegetables, fruits and healthy proteins. It is said that cruciferous vegetables are especially good at protecting the liver.
  • Exercise regularly.
  • Dont smoke and dont drink. Both tobacco and alcohol are bad for your liver.
  • Do things that help you cope with stress, like journaling, talking with others, meditating and doing yoga.
  • Avoid inhaling toxic fumes.

Who Should Be Vaccinated Against Hbv

The following high-risk groups should also receive the vaccine:

  • Those who have been in close contact with an individual infected with the hepatitis B virus.
  • Those that are regular intravenous drug users and often share needles
  • Health care professionals who have been in contact with HBV-infected patients.
  • Those that regularly go through dialysis treatment or other forms of blood transfusions.
  • Those who have had sexual contact with an HBV-infected individual.

Hepatitis C: Who Is At Risk

People who have injected illegal drugs at any time, even one time, many years ago, could be walking around with chronic hepatitis C. Because there are often no symptoms, many former drug users may not realize they have the infection. People who received a blood transfusion before 1992 also have a higher risk. Before that year, donated blood was not screened for the hepatitis C virus.

Hepatitis B Vaccine Schedule

  • Dosage depends on age and brand. The manufacturer’s guidance should be followed.
  • Injections are given intramuscularly in the upper arm or anterolateral thigh. It should not be given into the buttock.
  • The standard course of immunisation involves three injections at 0, 1 and 6 months.
  • An accelerated course of 0, 1 and 2 months is possible – also for combined hepatitis A and B vaccines.
  • Adults who need protection very quickly can have a schedule of 0, 7 and 21 days. Adults and children considered at very high risk should also have an accelerated schedule. After an accelerated course, a booster at one year is recommended.
  • Accelerated courses may also be best for drug abusers, as they are notoriously difficult to get to complete a course.

The duration of protection provided by the hepatitis B vaccine is still unknown but is believed to be at least 20 years.

The current UK recommendation is that those who have received a primary course of immunisation, including children vaccinated according to the routine childhood schedule and individuals at high risk of exposure, do not require a reinforcing dose of HepB-containing vaccine, except in the following categories:

Hepatitis B Vaccine

Years ago, the standard 3-round Hepatitis B vaccine provided protection for up to seven years. However, todays vaccines provide you with more than 20 years of protection.

This means that booster doses are largely unneeded these days. However, it is recommended for certain groups to take subsequent booster doses. At-risk groups include hemodialysis patients and other individuals with seriously compromised immune systems, such as people infected with HIV, chemotherapy patients, and recipients of hematopoietic stem-cell transplants.

How Common Is Hepatitis B

Hepatitis B is fairly common in Africa and the western Pacific region. Throughout the world, there are about 292 million people who are infected with chronic hepatitis B. In the U.S., the figure exceeds 2 million people.

The number of infections had been falling in the U.S., but fewer vaccinations among adults combined with the onset of the opioid crisis and injected drug usage has resulted in the numbers rising again. Infected women can pass the infection on to their babies. Children who are infected before age 5 are more likely to have chronic infection than those infected later in life.

What Is In The Hepatitis B Vaccine

Vaccines are given by a course of three injections, usually as part of the 6-in-1 vaccine scheme.

Although there are different types of vaccines, they usually contain one of the proteins from the surface of the hepatitis B virus thats then inserted in to the genetic code into yeast cells which stops the risk of viral DNA getting into the final product.

They also contain small amounts of sodium chloride and aluminium, and can contain yeast and formaldehyde.

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.

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 three, 3-dose vaccine brands approved in the U.S.

2-Dose Vaccine Series

Concerns About Immunisation Side Effects

Chronic hepatitis C: Symptoms, causes, and treatment

If a side effect following immunisation is unexpected, persistent or severe, or if you are worried about yourself or your childs condition after a vaccination, see your doctor or immunisation nurse as soon as possible or go directly to a hospital.

Immunisation side effects may be reported to SAEFVIC, the Victorian vaccine safety and central reporting service. Adverse events in other states or territories can be reported through SAEFVAC.

It is important to seek medical advice if you are unwell, as this may be due to other illness rather than because of the vaccination.

Managing Fever After Immunisation

Common side effects following immunisation are usually mild and temporary . Specific treatment is not usually required.There are a number of treatment options that can reduce the side effects of the vaccine including:

  • Drinking extra fluids to drink and not overdressing if there is a fever.
  • Although routine use of paracetamol after vaccination is not recommended, if fever is present, paracetamol can be taken check the label for the correct dose or speak with your pharmacist .

Baby Boomers Are Especially Vulnerable

âThe hepatitis C virus didnât have a name or a screening test until in 1989,â Reau says. âThat means people born between 1945 and 1965, the group referred to as âbaby boomers,â are at highest risk of infection. They grew up before health care facilities started taking standard precautions, like not sharing vials of medicine among patients and requiring staff to wear gloves.â

The CDC reports that baby boomers are five times more likely to have Hepatitis C than other adults, accounting for 75% of those living with the disease.

These are some other reasons you may be at risk:

  • You have engaged in high-risk behaviors like IV drug use or unprotected sex
  • Your biological mother has/had hepatitis C
  • You received blood transfusions, an organ transplant or dialysis before 1989
  • You were or are currently incarcerated

What Are Possible Complications Of Alcoholic Hepatitis

If you dont stop drinking and your condition worsens, your overall outcome and chances for recovery will worsen as well.

Alcoholic hepatitis can lead to hepatic encephalopathy. This condition occurs when the toxins typically filtered out by your liver remain in the bloodstream. These toxins can cause brain damage and lead to a coma.

Your outlook may worsen if you develop cirrhosis as a result of excessive alcohol use. Bleeding complications, anemia, and liver failure can become life-threatening.

How Do People Get The Hbv Virus

Hepatitis B vaccine for grade 7 students

Hepatitis B virus is found in the blood of people with HBV infection. It enters the body through blood-to-blood contact.

Reliable blood tests for HBV were developed many years ago. Since blood donors and blood products are tested for HBV, this is no longer the typical means of infection.

In many parts of the world, hepatitis B virus infects more than 8% of the population. HBV-infected women pass the infection to their babies during the birth process. People can also get hepatitis B by sharing needles for injection drug use, through sexual contact with an infected person, by an accidental needlestick with a contaminated needle, or from improperly sterilized medical, acupuncture, piercing, or tattooing equipment.
