Hepatitis B Vaccine Guide: Dosage, Schedule, Benefits and Safety

Hepatitis B is a liver infection that often causes no symptoms for years. Over time, it can quietly lead to liver scarring, liver failure and liver cancer. The reassuring part is that a safe, well-studied vaccine can prevent it. The hepatitis B vaccine in India is part of the routine immunisation schedule for newborns, and adults can take it at any age. This guide covers what the vaccine does, who needs it, the adult dose, the schedule, booster timing, safety and price. The WHO Global Hepatitis Report 2024 estimated that about 2.98 crore people in India were living with hepatitis B in 2022. Most of them do not know they carry the virus, which is why prevention matters so much.

What Is the Hepatitis B Vaccine?

The hepatitis B vaccine is a recombinant vaccine. It contains a purified protein from the surface of the hepatitis B virus, called HBsAg, and not the live virus. This means the vaccine cannot give you hepatitis B. Your immune system learns to recognise this protein and makes protective antibodies called anti-HBs. If you are exposed to the virus later, these antibodies stop it before it can settle in your liver. Common brands of the hepatitis B vaccine in India include Engerix-B, Genevac-B, Elovac-B and Biovac-B. Your doctor will choose the brand and strength that suit your age and health.

Hepatitis B Vaccine Uses: Who Should Get It?

The main use of the vaccine is to prevent hepatitis B infection and the long-term liver damage it can cause. Doctors especially recommend it for:

• All newborns, ideally within 24 hours of birth
• Children and adults who never started or never finished the vaccine series
• Doctors, nurses, lab staff and anyone who handles blood or body fluids
• People on dialysis or living with chronic kidney disease
• People with chronic liver disease, hepatitis C, HIV or diabetes
• Family members and sexual partners of a person with hepatitis B
• People with multiple sexual partners or who inject drugs
• People about to start cancer treatment or other therapy that weakens immunity, after a blood test

Many people search for hepatitis vaccine uses in general, so it helps to know the difference. Hepatitis A and hepatitis B have separate vaccines, and one does not protect against the other. There is no approved vaccine for hepatitis C yet. The hepatitis B vaccine also protects you from hepatitis D, because that virus can only infect people who have hepatitis B.

Benefits of Hepatitis B Vaccine

The advantages of hepatitis B vaccine reach far beyond avoiding a short illness. Key hep B vaccine benefits include:

• Strong protection: a complete series protects more than 95% of infants, children and young adults, according to the WHO. The response is lower after age 40 and in people with weak immunity.
• Lower liver cancer risk: by preventing chronic infection, the vaccine lowers the risk of liver cancer. The WHO describes it as the first vaccine that prevents a major human cancer.
• Protection from cirrhosis and liver failure: fewer chronic infections mean less long-term liver scarring.
• Safety for newborns: a birth dose greatly reduces the chance of a mother passing the virus to her baby.
• Long-lasting protection: in healthy people, protection lasts at least 30 years and often for life.

Hepatitis B Vaccine Schedule

Your hepatitis B vaccine schedule depends on your age and health. The table below shows how the hepatitis B vaccine in India is usually given.

Who	Number of doses	When the doses are given
Newborns (Universal Immunization Programme)	Birth dose + 3 doses	Birth dose within 24 hours, then pentavalent vaccine at 6, 10 and 14 weeks
Adults and older children (standard)	3 doses	0, 1 and 6 months
Adults needing faster protection (selected brands)	4 doses	0, 1, 2 and 12 months, or 0, 7 and 21 days plus 12 months
People on dialysis or with weak immunity	As advised	Higher-strength doses on a schedule set by the doctor

If you miss a dose, you do not need to start again. Simply take the next dose as soon as you can.

Hepatitis B Vaccine Schedule for Adults in India

Most adults follow the 0, 1 and 6-month schedule. You take the first dose on day one, the second dose a month later and the third dose six months after the first. Keep the minimum gaps: at least 4 weeks between doses 1 and 2, 8 weeks between doses 2 and 3, and 16 weeks between doses 1 and 3. The faster schedules suit people who need quick protection, such as before a surgery, but they need a fourth dose at 12 months.

Hepatitis B Vaccine Dose for Adults in India

The usual hepatitis B vaccine dose for adults in India is 20 mcg in 1 mL. It is injected into the muscle of your upper arm, not the buttock, because the buttock gives a weaker response. Children and younger teenagers usually receive 10 mcg in 0.5 mL, though this varies by brand. People on dialysis or with weak immunity may need a higher dose, such as 40 mcg, as advised by their doctor.

Hepatitis B Vaccine Duration and Booster Dose

A common question is how long the hepatitis B vaccine duration lasts. Healthy people who finish the series stay protected for at least 30 years. Your body keeps an immune memory, even when antibody levels drop over time.

When to Take Hepatitis B Booster Dose

Most healthy children and adults do not need a booster. Your doctor may advise one in these situations:

• You are on dialysis and your yearly antibody test falls below 10 mIU/mL
• You have a weakened immune system, such as from HIV or a stem cell transplant
• Your doctor finds low antibody levels after a known exposure or on routine testing

An anti-HBs blood test done 1 to 2 months after your last dose shows whether you are protected. A level of 10 mIU/mL or more is considered protective. Healthcare workers and people with weak immunity should take this test, which is available through clinical pathology in Pune. If your level stays low, your doctor may repeat the full series.

Hepatitis B Vaccine Side Effects and Safety

The hepatitis B vaccine has been used worldwide for decades and has a strong safety record. Most side effects are mild and settle within one or two days:

• Pain, redness or swelling where the injection was given
• Mild fever
• Tiredness, headache or a mild upset stomach

Serious allergic reactions are very rare. Avoid the vaccine if you had a severe allergy to an earlier dose or to yeast, since many brands are made using yeast. If you have a high fever, wait until you recover. Doctors consider the vaccine safe during pregnancy and breastfeeding when it is needed.

Why the Hepatitis B Vaccine Matters for Cancer Patients

Long-term hepatitis B infection is one of the leading causes of liver cancer worldwide. You can read more about how hepatitis raises liver cancer risk. Preventing the infection is one of the simplest ways to lower that risk. Hepatitis B also matters during cancer care. Some treatments, including chemotherapy and rituximab used for many blood cancers, can reactivate a hidden hepatitis B infection. This is called HBV reactivation, and it can cause serious liver injury. That is why oncologists test for hepatitis B before starting chemotherapy in Pune or blood cancer treatment in Mumbai. If you are not immune, your doctor may advise vaccination, ideally before treatment begins, or antiviral medicine. If you already have a liver cancer diagnosis, our liver cancer treatment in Mumbai page explains your options.

Hep B Vaccine Price in India

The hep B vaccine price in India depends on the brand, dose strength and where you take it. As a general guide, one dose costs about ₹100 to ₹1,500 at private pharmacies, clinics and hospitals. Many people search for the hep B1 vaccine price, which usually means the cost of the first dose. The first dose costs the same as the later ones. So a full adult course usually costs about three times the single-dose price, plus any consultation or injection fee. Several factors change the final amount:

• Brand and strength: adult 1 mL doses cost more than 0.5 mL child doses
• Vial type: single-dose vials and prefilled syringes cost more than multi-dose vials
• Facility: hospitals may charge an administration or consultation fee
• Testing: a pre-vaccination or anti-HBs blood test adds to the total

Under the Universal Immunization Programme, the hepatitis B vaccine in India is free for newborns and infants at government health centres. Prices change often, so confirm the current rate before you book.

Free Cancer Treatment Support Through Government Schemes

No hospital in India offers free cancer treatment to everyone as standard. However, government health schemes can cover most or all treatment costs for patients who qualify, including liver cancer and blood cancer care.

• [PM-JAY (Ayushman Bharat)]: cashless cover of up to ₹5 lakh per family per year at empanelled hospitals. Senior citizens aged 70 and above qualify regardless of income.
• [MJPJAY]: Maharashtra’s state health scheme for eligible resident families
• [CGHS]: for central government employees, pensioners and their dependants
• [ECHS]: for ex-servicemen and their dependants
• [MPKAY]: for Maharashtra police personnel and their families

Onco-Life Cancer Centre supports eligible patients under these schemes. Read more about free cancer treatment options or check the full list of government health insurance schemes. Eligibility rules apply, and these schemes mainly cover hospital treatment rather than routine adult vaccination.
