What is Hepatitis B Vaccine and How Does it Help?

Hepatitis B Vaccine is a type of vaccine formulated to prevent Hepatitis B virus. Hepatitis B can lead to liver cancer, cirrhosis and even death as it causes severe damage to the liver. Vaccination helps protect individuals from this type of virus because it has no cure. According to health experts, the best way to avoid Hepatitis B infection is to be vaccinated, as this provides lifetime protection against the contagious disease. In this article, we will be discussing everything you need to know about the hepatitis B vaccine, how it works, and why it is safe for both adults and infants.

Why You Should Be Vaccinated?

Hepatitis B is a contagious disease that causes extensive damage to the liver and can lead to lifelong illness if you are not vaccinated. Acute hepatitis B infection can occur within the first six months of exposure and can lead to fatigue, muscle pain, nausea, and jaundice. Chronic hepatitis B virus is a long-term illness that can lead to liver cancer or death. People who develop chronic hepatitis B may not realize the symptoms until they start experiencing the side effects of liver failure.

It is important to get a Hepatitis B vaccine as it helps prevent Hepatitis B infection. Although this vaccine consists of a small portion of the hepatitis B virus, it cannot cause HBV infection. Getting the vaccine earlier helps to boost your immune system, which provides ultimate protection against the Hepatitis B virus.

How Does The Hepatitis B Vaccine Help?

Hepatitis B vaccine can help prevent the consequences of hepatitis B by helping you develop a strong immune system that works against the infection. Infants usually receive the first dose of Hepatitis B vaccine at birth before they complete the series at 6 months of age. Adults aged 18 and older may be given a two-dose vaccine that is usually administered one month apart.

After the immunization, the vaccine helps protect against the Hepatitis B virus by stimulating your natural immune system. It produces antibodies in the blood that act in response to Hepatitis B virus when it attempts to invade the body. As a result, the antibodies fight off the infection when an individual is exposed to the virus in the future.

This type of response is known as active immunity, which is boosted or reinforced when the vaccine is given in series. It is not necessary to add more doses if the vaccination series is interrupted or the duration between doses is longer than what is recommended. According to health experts, you need to continue the series from where it was interrupted to complete the vaccination. There are also catch up series recommendations depending on the age of the unvaccinated person. Hepatitis B vaccine provides long-term protection against the Hepatitis B virus and should be given to both infants and adults.

Is Hepatitis B Vaccine Safe?

The Centers for Disease Control and Prevention (CDC) usually monitors the safety of different types of vaccines once they are approved. They use several systems to check vaccine safety before informing health care providers, health officials, and the public. According to extensive research from medical experts, the Hepatitis B vaccine is considered safe with little or no side effects. Some of the common side effects of the Hepatitis B vaccine include fever and a sore arm from the shot. On very rare occasions, some people may experience allergic reactions upon receiving the Hepatitis B shot. The vaccine is not often recommended for people who are allergic to yeast or other components of the vaccine.

When to See the Doctor

Many side effects of the Hepatitis B vaccine are mild and may fade away on their own. The discomfort or soreness at the injection site is common and usually lasts for at least 24 to 48 hours. It is important to consult a doctor if you start experiencing rare or uncommon side effects. This may help determine whether the vaccine is the cause of the symptoms or other underlying health conditions.

Hepatitis B infection has no cure and the only way you can prevent it is by getting the Hepatitis B vaccine. Hepatitis B may lead to life-threatening complications, as it causes extensive damage to the liver. The infection rate drops significantly when you receive a Hepatitis B vaccine at the right time and adhere to a series of follow-up vaccines. It helps boost your immune system by producing antibodies that help fight off Hepatitis B infection in the future.
