What’s In The Hepatitis B Vaccine

What Is Hepatitis B Vaccine

mRNA vaccines, explained

Hepatitis B is a serious disease caused by a virus. Hepatitis causes inflammation of the liver, vomiting, and jaundice . Hepatitis can lead to liver cancer, cirrhosis, or death.

The hepatitis B adult vaccine is used to help prevent this disease in adults. The dialysis form of this vaccine is for adults receiving dialysis.

This vaccine helps your body develop immunity to hepatitis B, but it will not treat an active infection you already have.

Vaccination with hepatitis B adult vaccine is recommended for all adults who are at risk of getting hepatitis B. Risk factors include: living with someone infected with hepatitis B virus having sexual contact with infected people having hepatitis C, chronicliver disease, kidney disease, diabetes, HIV or AIDS being on dialysis using intravenous drugs living or working in a facility for developmentally disabled people working in healthcare or public safety and being exposed to blood or body fluids living or working in a correctional facility being a victim of sexual abuse or assault and traveling to areas where hepatitis B is common.

Like any vaccine, the hepatitis B vaccine may not provide protection from disease in every person.

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.

Reducing Your Risk Of Hepatitis A

You can reduce your risk of being infected with hepatitis A or passing on hepatitis A by using condoms for anal sex, washing your hands after handling condoms, and using a latex barrier and gloves during sexual intercourse. Govind stresses the importance of avoiding sex that involves contact with faeces.

In most cases, hepatitis A is diagnosed by a GP rather than at sexual health clinics. This is because if a person feels unwell, they are likely to contact their doctor, who can perform a blood test to determine if hepatitis is present.

Most people tend to recover fully from hepatitis A without complications and once you have had it, it is extremely unlikely that you will get it again since antibodies from your previous infection can offer protection.

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.

Hepatitis B Vaccine Side Effects

Drive

The hepatitis B vaccine is considered a very safe and effective vaccine. Its made with an inactivated virus, so most types of the vaccine are even safe for pregnant people.

The hepatitis B vaccine may cause some mild side effects. The most common symptom is redness, swelling, or soreness where the injection was given. Some people also experience headache or fever. These effects usually last a day or two .

Rarely, some people have a serious and potentially life threatening allergic reaction to the vaccine. Call 911 or get to a hospital immediately if you experience any of the following symptoms after vaccination:

  • hives

What Are My Next Steps Once I Get My Results

It can be difficult to understand what the results of your test mean. A healthcare provider can help you interpret your results and decide whether you need to take further action:

  • If your results suggest that youre already immune to hepatitis B and arent contagious, you likely wont need to do anything.
  • If your results suggest that youre not immune, a doctor may recommend vaccination, especially if youre somebody whos at a high risk of infection.

You may also need additional testing if more information is needed to interpret your results.

Whats The Hepatitis B Titer Test Used For

A hepatitis B titer test measures antibodies in your blood to see if youre immune either due to vaccination or previous infection.

Hepatitis B is a viral infection that targets your liver. It can be transmitted by coming into contact with the bodily fluids of an infected person. A person with the virus can also infect their child during birth.

Hepatitis B can develop into a chronic infection. Chronic infection occurs when your body cant fight off the virus within six months. Chronic hepatitis B infections most commonly develop less than six years old, especially in infants.

Hepatitis B titer tests can be used to evaluate:

  • whether a high-risk person is immune to hepatitis B
  • whether hepatitis B immunoglobulin is needed after a needle prick
  • men who have sex with men
  • people born in countries with a hepatitis B prevalence greater than 2 percent
  • people born in the United States not vaccinated as children and with parents born in regions with more than 8 percent hepatitis B prevalence

You may need your titer test results as proof of hepatitis B immunity in order to get into healthcare programs at many schools for example, the nursing program at Lone Star College. In the United States, employers are not allowed to withdraw a job offer if they learn you have hepatitis B.

How Do Inactivated Viral Vaccines Work

Inactivated viralvaccines are sterile biologic products that provide immunity against viral infections. Inactivated viral vaccines work by stimulating the bodys immune system to produce antibodies against specific types of viruses, and protect a person from becoming infected when exposed to these viruses.

In the case of SARS-CoV-2 coronavirus that causes respiratory illness and has led to the COVID-19 pandemic, vaccines do not entirely prevent infection but protect vaccinated individuals from serious illness and hospitalization from the disease.

Inactivated viral vaccines contain particles of proteins or genetic material from viruses. Inactivated viral vaccines may also contain substances that preserve and stabilize the vaccine, and enhance immune response. Some viral vaccines are delivered in inactivated harmless viruses such as human adenovirus.

Inactivated viral vaccines may be made from:

  • Surface proteins of the viruses enable the virus to hold on to a human cell, enter inside and replicate.
  • Modified RNA particles from the virus can enter host cells and induce the production of viral antigen, which stimulates an immune response from the body.
  • Recombined DNA material from multiple strains and subtypes of viruses, killed to eliminate disease-causing capability.

Currently, inactivated viral vaccines approved by the FDA protect against viral infectious diseases that include:

  • Coronavirus disease , caused by SARS-Cov-2 virus
  • Routine poliovirus vaccine prophylaxis
  • Adults

    Sex and gender exist on spectrums. This article will use the terms, male, female, or both to refer to sex assigned at birth. .

    It is important that infants who are born to females with hepatitis B receive accurate doses of the hepatitis B vaccine. They may also be required to receive hepatitis B immunoglobulin if it is available.

    The WHO also recommends using antiviral prophylaxis to help prevent hepatitis B transmission.

    The table below outlines the two recommended hepatitis B vaccine schedules for infants born to those who have hepatitis B:

    Hepatitis Vaccine: What You Need To Know

    Hepatitis is an inflammatory liver condition. There are five types of viral hepatitis: A, B, C,D, and E. Most cases are caused by a hepatitis virus. The condition can also be a result of excessive alcohol or drug use or a faulty inflammatory immune response that occurs when the immune system mistakes the liver as a threat to the body and begins to attack it.

    There are two hepatitis vaccines that can help prevent hepatitis A and B infections. A third vaccine, developed for hepatitis E, is only permitted for use in China. This article discusses the types of hepatitis that can be prevented with a vaccine and what you need to know before getting one.
