Hepatitis B vaccination at Klinik Dr. Prevents Damansara Jaya — a 3-dose series protecting against chronic Hepatitis B infection and its serious long-term complications including liver failure and liver cancer. Available for all ages, open 24 hours, no appointment needed.
Hepatitis B is a viral infection that attacks the liver. In most adults who contract it, the body clears the virus within a few months. But when infants and young children become infected — particularly newborns infected during delivery from a mother who carries the virus — approximately 90% go on to develop chronic Hepatitis B infection. Chronic Hepatitis B slowly damages the liver over decades, often without obvious symptoms, and significantly increases the risk of cirrhosis and liver cancer.
Malaysia has a moderate prevalence of Hepatitis B — approximately 2–3% of the population are chronic carriers. This makes vaccination not just recommended but essential, particularly for newborns whose immune systems will mount a much stronger long-term protective response from early vaccination than from vaccination in adulthood.
The vaccine is given in a 3-dose series — at birth, at 1 month, and at 6 months. It is one of the safest and most well-studied vaccines in the world, with immunity typically lasting a lifetime. Adults who were never vaccinated as children can and should receive catch-up vaccination — visit our adult vaccination or children's vaccination page to learn more.
First dose given within 24 hours of birth — ideally at the maternity hospital. If missed, administer as soon as possible.
Second dose given 4 weeks after the first dose. Builds on the initial immune response and prepares for full protection.
Third and final dose completing the primary series. After this dose, immunity is considered long-term and potentially lifelong.
Approximately 2–3% of the Malaysian population are chronic Hepatitis B carriers — far higher than in many Western countries. This makes vaccination an especially important priority for families in the Klang Valley.
When a newborn contracts Hepatitis B — typically during birth from an infected mother — 9 out of 10 will develop chronic infection. Vaccinating at birth almost entirely eliminates this risk.
Hepatitis B vaccination is the world's first cancer-prevention vaccine. Chronic Hepatitis B is a major cause of liver cancer — vaccination interrupts this progression before it begins.
Hepatitis B is spread through blood, sexual contact, and from mother to child. Adults who were never vaccinated face ongoing risk — a catch-up series provides the same strong protection at any age.
A simple blood test — Hepatitis B surface antibody (anti-HBs) — shows whether you already have immunity from prior vaccination or infection. If the level is low, a booster may be appropriate. Ask our doctor.
Each dose in the 3-dose series is a quick, straightforward injection — most visits completed within 20 minutes.
No appointment needed. Tell our team which dose you're here for. Bring your vaccination card or child's Kad Kesihatan if available.
Your doctor confirms which dose is due, checks for any contraindications, and verifies your vaccination record to ensure the correct timing between doses.
