Hepatitis A+hepatitis B Recombinant Vaccine
About Hepatitis A+hepatitis B Recombinant Vaccine
Hepatitis A+hepatitis B Recombinant Vaccine is a combined vaccine used to prevent infections caused by the hepatitis A and hepatitis B viruses. It works by helping your body produce its own protection (antibodies) against these two serious liver infections. This vaccine is typically recommended for adults who are at risk of contracting both viruses due to travel, lifestyle, occupation, or underlying health conditions.
To ensure maximum protection, this vaccine is given as a series of injections over a specific timeline, usually requiring three doses over six months. It is injected into a muscle by a healthcare professional, so food intake does not affect its absorption. Supporting your immune system through healthy habits can help your body build a stronger defence after receiving your shots.
Most people tolerate this vaccine well, though you may experience mild, temporary side effects like soreness at the injection site, mild headaches, or feeling tired. Serious reactions are rare, but you should seek immediate medical attention if you experience severe dizziness, trouble breathing, or swelling of your face, lips, or tongue after receiving an injection.
Talk to your doctor before starting this vaccination series if you have any bleeding disorders, a high fever, or a weakened immune system due to illness or medication. Do not take this if you have ever had a life-threatening allergic reaction to yeast or to a previous dose of this vaccine.
Certain medications, such as immunosuppressants or chemotherapy, can make the vaccine less effective because they lower your body's ability to build antibodies. It is also wise to limit alcohol consumption around the time of your injections, as alcohol can strain your liver and temporarily weaken your immune system. If you are pregnant, breastfeeding, or planning a pregnancy, consult your doctor to determine if vaccination is appropriate for you.
Uses of Hepatitis A+hepatitis B Recombinant Vaccine
Medicinal Benefits
Hepatitis A+hepatitis B Recombinant Vaccine is a combination vaccine that helps protect against hepatitis A and hepatitis B, two viral infections that can affect the liver.
- Helps Prevent Hepatitis A: Stimulates the immune system to protect against hepatitis A, which can cause inflammation of the liver and symptoms such as fatigue, nausea, abdominal discomfort, and jaundice.
- Helps Prevent Hepatitis B: Provides protection against hepatitis B, which can sometimes become a long-term infection and lead to serious liver complications such as cirrhosis or liver cancer.
- Provides Combined Protection: Protects against both infections through a single vaccination programme, reducing the need to receive separate hepatitis A and hepatitis B vaccines.
- Supports Long-Term Prevention: Completing the recommended vaccination schedule helps develop and maintain immunity against both hepatitis A and hepatitis B.
- Useful for People at Increased Risk: Combined vaccination may be particularly useful for eligible individuals with increased exposure risk, including certain travellers, healthcare workers, and people at risk of hepatitis A or B infection.

Drug Warnings
- Inspect the Vaccine Before Administration: The vaccine should have the appearance specified in the product instructions and should not contain unexpected particles or abnormal discolouration. The healthcare professional should inspect it before administration.
- Use the Recommended Injection Site: The vaccine is generally administered into the deltoid muscle in adults and older children. Avoid administration into the buttock, as this may result in a less reliable immune response.
- Inform Your Healthcare Provider About Bleeding Risks: Tell the vaccinator if you have a bleeding disorder or take anticoagulant or antiplatelet medicines, as you may have a higher risk of bruising or bleeding at the injection site.
- Remain Seated After Vaccination: Stay seated or lying down for about 15 minutes after vaccination, particularly if you have previously felt faint after injections, to reduce the risk of injury from dizziness or fainting.
- Inform Your Doctor About Illness: If you have a moderate or severe acute illness, particularly with a high fever, tell your healthcare provider before vaccination. Vaccination may be postponed until you recover.
Drug Interactions
Inform your doctor about all medicines and vaccines you are receiving before getting Hepatitis A+hepatitis B Recombinant Vaccine:
- Immunosuppressive medications: Drugs that weaken your immune system, such as chemotherapy, high-dose oral steroids, or medications taken after an organ transplant, may prevent your body from building a strong immune response to the vaccine, making it less effective.
- Other vaccines: While Hepatitis A+hepatitis B Recombinant Vaccine can be given at the same time as other routine vaccines, they must be injected using different syringes and at different injection sites on your body.

Patients Concern
Disease/Condition Glossary
Hepatitis A: It is a liver infection caused by the hepatitis A virus (HAV). It can be prevented by effective vaccination. It spreads through contaminated food or water and contact with infected persons. Symptoms include abdominal pain, nausea, loss of appetite, tiredness, dark urine, yellowing eyes and skin, clay-coloured stool, and fever. Adequate rest and hydration can help in quick recovery.
Hepatitis B: It is a severe liver infection caused by the hepatitis B virus (HBV). It is highly contagious (spreads from one person to another) and spreads through intimate contact with the infected person, direct contact with infected blood, through a contaminated needle, using an infected razor or other personal items, or from mother to baby during birth. The symptoms of hepatitis B may appear after three months of exposure to the virus and can last for 2 to 12 weeks. The complications of chronic hepatitis B include liver failure, liver cancer, or liver cirrhosis (scarring). Hepatitis B can be prevented by taking the vaccination.
FAQs
Hepatitis A+hepatitis B Recombinant Vaccine is used to prevent hepatitis A and Hepatitis B infections.
Hepatitis A+hepatitis B Recombinant Vaccine contains Hepatitis A vaccine and Hepatitis B recombinant vaccine. Hepatitis A vaccine contains inactivated or live attenuated viruses to stimulate the immune system. The hepatitis B vaccine is obtained by culturing genetically engineered yeast cells that carry the hepatitis B virus surface antigen gene. Together, Hepatitis A+hepatitis B Recombinant Vaccine provides dual immunity against hepatitis A and B by stimulating the immune system to recognize and fight both viruses.
It is not advised to take live vaccines such as MMR (measles, mumps, and rubella) or varicella (chickenpox) within 3 months of taking Hepatitis A+hepatitis B Recombinant Vaccine. These vaccination actions may be altered, making them less effective.
You may experience flu-like symptoms and fever after getting vaccinated with Hepatitis A+hepatitis B Recombinant Vaccine. This is a common side effect that occurs after every vaccine. Your fever gradually decreases after 1-2 days. Your doctor may also suggest fever and pain medication if required. However, please reach out to your doctor if the fever persists after three days.
Hepatitis A+hepatitis B Recombinant Vaccine may cause side effects such as pain, redness, or swelling at the injection site, headache, feeling tired, diarrhoea and signs of a common cold. If any of these side effects persist or get worse, inform your doctor immediately.
Hepatitis A, hepatitis B, and hepatitis C are three different viruses that cause severe liver infection. Though each virus of hepatitis can cause similar symptoms, they are spread in different ways and can affect the liver differently. Hepatitis A causes short-term infection. While hepatitis B and C can begin with short-term infections, in some cases, they can cause chronic or lifelong infections. There are vaccines to prevent hepatitis A and B, but no vaccine is available for hepatitis C.
No, Hepatitis A+hepatitis B Recombinant Vaccine cannot cause hepatitis. The vaccine contains completely inactivated hepatitis A virus and only a purified surface protein of the hepatitis B virus, neither of which can cause active infection or illness. Talk to your doctor if you have concerns about vaccine safety.
If you miss a dose, you do not need to restart the entire vaccination series from the beginning. Simply contact your clinic as soon as possible to get the missed injection and get back on track. Talk to your doctor or pharmacist about catch-up timing.
Do not take Hepatitis A+hepatitis B Recombinant Vaccine if you have a known, severe allergy to yeast. The hepatitis B component of the vaccine is produced using yeast cells, and trace amounts may remain, which could trigger a dangerous allergic reaction. Talk to your doctor for alternative options.
