When Should I Get Hepatitis B Vaccine

Does The Hepatitis B Vaccine Have Side Effects

Why Are Adults 19 to 59 Recommended to Get the Hepatitis B Vaccine?

Some children will develop pain or soreness in the local area of the shot, and low-grade fever.

There is one extremely rare, but serious, side effect. About 1 out of every 600,000 doses of the hepatitis B vaccine will cause a severe allergic reaction, called anaphylaxis, with symptoms including swelling of the mouth, difficulty breathing, low blood pressure or shock. Anaphylaxis usually occurs within 15 minutes of receiving the vaccine. Although anaphylaxis can be treated, it is quite frightening. People should remain at the doctors office for about 15 minutes after getting the vaccine.

Although the hepatitis B vaccine is made in yeast cells, no one has ever been shown to be allergic to the yeast proteins contained in the hepatitis B vaccine .

How And When Do Doctors Give Vaccines

For the hepatitis A vaccine:

You should get two doses, given as shots, 6 months apart for complete protection. The virus in the vaccine is killed .

Children should get the first dose between 12 and 23 months of age. Children older than age 2 can get the first dose at their next doctorâs visit.

If you need the vaccine because of upcoming travel, get it at least 1 month before you go.

For the hepatitis B vaccine:

For long-lasting immunity, you need three to four doses, depending on which type of vaccine is used. You get them as shots.

Children should get their first dose at birth and complete the series by age 6 months. Usually, the baby would get a second dose at 1 month old and the third dose at 6 months.

Babies born to women who have hepatitis B need a shot of hep B antibodies, as well as their first hep B vaccine shot, when theyâre born. They will also need follow-up blood tests to make sure theyâre OK.

Catch-up vaccinations are recommended for children and teens who were never vaccinated or who did not get all three shots.

If you’re an adult who wants to be vaccinated, you should talk about it with your doctor or pharmacist. If you are considering both vaccines, ask your doctor about vaccines that combine hep A and B.

Why Should My Baby Get The Hepatitis B Shot

  • Protects your child from against hepatitis B, a potentially serious disease.
  • Protects other people from the disease because children with hepatitis B usually dont have symptoms, but they may pass the disease to others without anyone knowing they were infected.
  • Prevents your child from developing liver disease and cancer from hepatitis B.
  • Keeps your child from missing school or child care and you from missing work.

Why Do You Need A Hepatitis B Shot

Hepatitis B is a viral infection that cant be transferred person-to-person unless you have contact with an infected persons bodily fluids. Annual infection rates of HBV are going down in the United States thanks to vaccines. So you might be wondering if you or your child needs a shot to protect against hepatitis B.

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.

Don’t Miss: Low Immunity To Hepatitis B

Origin Of Antiviral Resistance

The genetic makeup of viruses is constantly changing, which can cause a virus to become resistant to currently available treatments. Viruses can become resistant through spontaneous or intermittent mechanisms throughout the course of an antiviral treatment. Immunocompromised patients, more often than immunocompetent patients, hospitalized with are at the highest risk of developing oseltamivir resistance during treatment. Subsequent to exposure to someone else with the flu, those who received oseltamivir for post-exposure prophylaxis are also at higher risk of resistance.

Multiple strains of one virus can be present in the body at one time, and some of these strains may contain mutations that cause antiviral resistance. This effect, called the , results in immense variation in any given sample of virus, and gives the opportunity for natural selection to favor viral strains with the highest fitness every time the virus is spread to a new host. Also, recombination, the joining of two different viral variants, and , the swapping of viral gene segments among viruses in the same cell, play a role in resistance, especially in influenza.

Antiviral resistance has been reported in antivirals for herpes, HIV, hepatitis B and C, and influenza, but antiviral resistance is a possibility for all viruses. Mechanisms of antiviral resistance vary between virus types.

If I Already Have Hepatitis B Can The Vaccine Treat It

No. The hepatitis vaccine prevents hepatitis, but doesnt cure it if you already have it. If you have hepatitis B, there are other treatment options.

However, if you recently got exposed to the hepatitis B virus and you havent had the vaccine yet, tell your doctor right away. The vaccine and possibly other treatment can reduce your chances of getting hepatitis B if you get it within 2 weeks after you came into contact with the virus. The sooner you seek care after being exposed to hepatitis B, the better, so try to get there right away.

Do The Benefits Of The Hepatitis B Vaccine Outweigh Its Risks

Every year in the United States about 2,000 people die following an overwhelming hepatitis B virus infection. In addition, every year about 22,000 people are infected with hepatitis B. Some of them will remain chronically infected, putting them at high risk of the long-term consequences of hepatitis B virus infection: cirrhosis and liver cancer. In fact, with the exception of influenza and COVID-19 viruses, hepatitis B virus causes more severe disease and death in the United States than any other vaccine-preventable disease. On the other hand, the hepatitis B vaccine is an extremely rare cause of a severe allergic reaction called anaphylaxis. To date, no one has died from this reaction, but it is theoretically possible that this could occur.

Because hepatitis B virus is a common cause of severe disease and death in the United States, and because the hepatitis B vaccine does not cause permanent damage or death, the benefits of the hepatitis B vaccine clearly outweigh its risks.

Hepatitis B Vaccination Schedule For Children And Infants

  • 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.

Why You Should Get The Hepatitis B Vaccine

During the Covid-19 pandemic, there has been much controversy over vaccines. Although there has always been an anti-vaccine movement, it has grown during the pandemic. However, despite all of that, it is highly recommended that people who are at risk get the hepatitis B vaccine. Almost 300 million people worldwide have chronic hepatitis B and almost 800,000 people die every year due to hepatitis B complications. In fact, hepatitis B is the greatest risk factor for developing liver cancer . The hepatitis B vaccine is simple and effective. It requires either 2 or 3 shots over a few months. It is one of the most-administered vaccines worldwide, and one of the safest, with few side effects!

There are many groups that may need the vaccine. These include but are not limited to:

Now, this is a large list of people who might need the vaccine, but how hard is it to receive one? It is one of the easiest vaccines to get. Most hospitals carry the vaccine, and in the UK, hospitals are required to give the vaccine to at-risk groups. In the United States, the Affordable Care Act should cover preventive services so the hepatitis B vaccine should be mostly available free of cost.

If you are unsure of your hepatitis B status, ask your doctor or primary care provider to become tested! The hepatitis B test is super simple it only requires one blood sample. Your doctor should order the hepatitis B panel which includes different tests. Read more hepatitis B testinghere!

How Hepatitis Is Spread

Hepatitis A: About 20,000 people in the U.S. contract hepatitis A each year. The hepatitis A virus is found in the stool of the infected person. It is spread through contaminated food or water or by certain types of sexual contact.

Children who get hepatitis A often don’t have symptoms, so they can have the virus and not know it. However, they can still spread it easily. Fortunately, children are now routinely vaccinated against hepatitis A.

Most people who get hepatitis A recover completely within two weeks to six months and don’t have any liver damage. In rare cases, hepatitis A can cause liver failure and even death in older adults or people with underlying liver disease.

Hepatitis B: Every year, about 40,000 people in the U.S. become infected with hepatitis B. Acute hepatitis lasts from a few weeks to several months. Many infected people are able to clear the virus and remain virus-free after the acute stage. However, for others, the virus remains in the body, and they develop chronic hepatitis B infection, which is a serious, lifelong condition. About 1.2 million people in the U.S. have chronic hepatitis B. Of these, 15% to 25% will develop more serious health problems, such as liver damage, cirrhosis, liver failure, and liver cancer, and some people die as a result of hepatitis B-related disease.

Hepatitis B cannot be spread by contaminated water, food, cooking, or eating utensils, or by breastfeeding, coughing, sneezing, or close contact such as kissing and hugging.

Hepatitis B Vaccine Schedule For Adults

Hepatitis

Hepatitis B is a vaccine-preventable viral disease that involves inflammation of the liver.

The hepatitis B virus usually leads to a short-term infection known as acute hepatitis B. If their infection is left untreated, some people develop chronic hepatitis B. Chronic hepatitis B is a serious, permanent condition that can cause organ damage, cirrhosis , liver cancer, liver failure, and even death.

According to the Centers for Disease Control and Prevention , all people should be vaccinated against hepatitis B starting at birth. Adults who are at risk of developing hepatitis B should also receive the vaccine, which is highly effective in preventing infection.

Read on to learn more about the hepatitis B vaccine for adults, including who should receive it, the details of the dosage schedule, side effects, and more.

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.

Why Should I Vaccinate My Newborn Child If I Know That I Am Not Infected With Hepatitis B Virus

Before the hepatitis B vaccine, every year in the United States about 18,000 children were infected with hepatitis B virus by the time they were 10 years old. This statistic is especially important because people are much more likely to develop liver cancer or cirrhosis if they are infected early in life, rather than later in life .

About 9,000 of the 18,000 children infected in the first 10 years of life caught the virus from their mother during birth. However, many young children didn’t catch the disease from their mother. They caught it from either another family member or someone else who came in contact with the child. Because hepatitis B can be transmitted by relatively casual contact with items contaminated with the blood of an infected person, and because many people who are infected with hepatitis B virus don’t know that they have it, it is virtually impossible to be “careful enough” to avoid this infection.

For these reasons, all young children are recommended to receive the hepatitis B vaccine. The best time to receive the first dose is right after birth. This will ensure that the child will be protected as early as possible from catching hepatitis B from people who dont know that they are infected with the virus.

How Does The Hepatitis B Vaccine Series Work

The vaccine protects you from the hepatitis B virus by getting your body’s immune system to make antibodies. Those antibodies protect you by fighting off the virus if it ever gets into your body.

Usually, the vaccine is spaced out into three different shots called a hepatitis B vaccine schedule. One month after your first shot, you get the second shot. Six months after your first shot, you get the third shot. If you miss your second or third dose, get it as soon as you remember.

The hepatitis vaccine is super effective. Its worked really well to lower the number of people who get hepatitis B every year.

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.
