What is Hepatitis B Vaccine for?
Hepatitis B refers to an infectious type of liver infection caused by the Hepatitis B virus (HBV). It is a common infectious disease in Hong Kong. Around one-tenth of adults and nearly all perinatally infected infants cannot eliminate HBV from the body and are carriers of this virus. These people are susceptible to liver disease, liver cancer and chronic hepatitis. Carrier mothers may pass hepatitis B to their children. Vaccination against Hepatitis B can reduce your chance of getting an infection.
In Hong Kong, free Hepatitis B Vaccines are introduced to newborn infants. Infants will complete their doses in the first month, 1 month later and 5 months after the first dose respectively. For infants with carrier mothers, Hepatitis B immunoglobulin will be simultaneously injected with the first dose. Although Hepatitis B vaccination has been popular for decades, it is not significantly less influential in Hong Kong due to existing carriers and immigrants.

Hepatitis B vaccine is only available as injections. Adults will complete their three doses in the first month, a month later and 5 months after the first dose respectively.
