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.

Symptoms And Causative Agent

Hepatitis is a general term for inflammation of the liver, which may result from infectious or non-infectious causes. Viruses responsible for many cases of infectious hepatitis include hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E. Hepatitis A and B are the only hepatitis viruses for which vaccines are currently available in the United States .

The hepatitis B virus is a partly double-stranded DNA virus in the hepadnavirus family. The hepatitis A virus is a single-stranded RNA virus in the Picornavirus family. Both viruses, though structurally unrelated, infect and replicate primarily in liver cells.

The symptoms of acute hepatitis A infection are identical to those of hepatitis B infection. Early symptoms are headache, nausea, vomiting, abdominal pain, fever, rash, body aches and pains, and dark colored urine. Following this phase, jaundice , light stools, and liver pain may appear.

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.

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 virus, 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.

Are Hepatitis B Virus Infections Easily Avoided

Dr. David Hill On the Life-Saving Hepatitis B Vaccine

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 don’t know that they are infected, it is very hard to avoid the chance of getting infected with hepatitis B virus.
