The hepatitis B virus (HBV) is spread through blood and other bodily fluids and can cause a liver infection. There are two types.
Acute HBV lasts for a short amount of time, and people often make a full recovery. In some cases, it can progress to a chronic condition. Chronic HBV can be managed but not cured, and can result in serious complications. It's estimated that around
The hepatitis B vaccine can protect you from contracting the virus that causes hepatitis B infections. HBV vaccines have been safely used since the early 1980s. As of 2020, the World Health Organization
Virologists have developed recommendations for vaccinations to protect against hepatitis B. The schedule is based on the type of vaccine you will receive.
In children
The recommendations for hepatitis B vaccine for children are:
- First dose: within 24 hours of birth
- Second dose: 1-2 months of age
- Third dose: 6-18 months of age
In adults
Adults who were not vaccinated as children can also pursue a three-dose schedule:
- First dose: as soon as you are able
- Second dose: 1 month after the first dose
- Third dose: 6 months after the first dose
There are certain brands of vaccines that follow a different schedule.
What to do if you miss a scheduled dose
The recommended schedule for the HBV vaccine follows a three-dose pattern, with all doses complete within 6 months. The good news is that if you miss a dose, you
If you missed getting the second dose 1 month after the first, make an appointment as soon as possible. If you miss the third dose, you should also try to get it as quickly as possible. Keep in mind that the second and third doses
For children
The brand names for the three-dose hepatitis B vaccines most commonly used in the United States are:
- Engerix-B (made by GlaxoSmithKline)
- Recombivax HB (made by Merck)
- Pediarix (a combination vaccine that includes DTaP and inactivated poliovirus; usually given in four doses)
For adults
In addition to Engerix-B and Recombivax HB, there's another HBV vaccine approved for adults in the United States. This vaccine is called HEPLISAV-B.
This formula is newer but it's believed to be just as effective. It requires two doses instead of three, and the second dose can be administered 4 weeks after the first. HEPLISAV-B is currently
There's also the option to get vaccinated for hepatitis B and hepatitis A at the same time. Twinrix (made by GlaxoSmithKline) can be given in three or four doses. Twinrix typically follows the same schedule as the other HBV vaccines, but it
Adults who were vaccinated as children, and people who are pregnant, are
As stated above, adults who get the Twinrix vaccine on an accelerated schedule will need a booster shot after 12 months.
People who are on dialysis may be advised by their healthcare provider to get a booster shot. People with an ongoing risk of HBV exposure, who have taken a blood test that shows their immunity to the virus has weakened, may also be advised to get a booster. In general, most people won't need to get a HBV booster during their lifetime.
Hepatitis B is a viral infection that can't be transferred person-to-person unless you have contact with an infected person's 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.
Hepatitis B can cause serious health complications
Most adults with acute HBV make a full recovery after getting the virus that causes it. However, not everybody does. The CDC reported that
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
Children between the ages of 1 and 5 who get an HBV infection have a
If you're pregnant, you'll most likely have a blood test to see if you're positive for hepatitis B. This allows doctors to find out if there's a chance that you could pass on the virus. These tests are highly sensitive and have a good accuracy rate, but they aren't 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.
Many people with HBV don't know they have it
HBV infections are becoming less common in the United States. But HBV is still widespread in other parts of the world. Around
HBV can be transmitted through sexual contact and the use of IV drugs (transmission is more likely in areas with higher rates of HBV infections), and other risk factors. Although rare, there
There are potential side effects for adults and children in the days following a dose of the HBV vaccine.
Common side effects include:
- pain, swelling, or redness at the injection site
- fever
- headache
- runny nose or nasal congestion
Severe side effects from the hepatitis B vaccines are rare, but have been reported. Seek emergency medical assistance if you notice any of the following after a dose of HBV vaccine:
- hives
- difficulty breathing
- dizziness
- muscle weakness
- swelling of your face or throat
The schedule for the hepatitis B vaccine is based on which type of vaccine you receive. Most HBV vaccines for children and adults are administered in a three-dose series over the course of 6 months.
Vaccination for hepatitis B is currently recommended for all babies, starting at birth, but certain people at higher risk of HBV infection should make sure they have been fully vaccinated.
The HBV vaccine can cause side effects. Speak to a doctor if you have any questions or concerns about these vaccines or your risk for HBV.
