Hepatitis B Vaccine Singapore.

Hepatitis B Vaccine Singapore: Hepatitis B (Recombinant) vaccine jab/shot/injection schedule, to vaccinate against the hepatitis B virus, to immunise against hepatitis B infection of the liver clinic, Singapore. Private and confidential service. Definitions, references, and latest news.

Contents

Hepatitis B vaccine is produced by recombinant DNA technology, most commonly in yeast. The complete series consists of three doses of vaccine; the first two doses are usually given 1 month apart, with the third dose 1–12 months later. The WHO-recommended schedule for hepatitis B immunization of children consists of a dose within 24 hours of birth followed by a second and third dose of hepatitis B-containing vaccines at intervals of at least 4 weeks.

A complete series of immunization provides protection for at least 15 years and, according to current scientific evidence, probably for life. Boosters are not recommended for routine immunization programmes.

Because of the prolonged incubation period of hepatitis B, some protection will be afforded to most travellers following the second dose given before travel. However, the final dose should always be given.

A combination vaccine that provides protection against both hepatitis A and hepatitis B should be considered for travellers who may be exposed to both organisms. This inactivated vaccine is administered as follows: day 0; 1 month; 6 months. A rapid schedule of day 0, 1 month and 2 months with an additional dose at 12 months, and a very rapid schedule of day 0, day 7 and day 21 with a booster dose at 12 months, have been proposed by the vaccine manufacturer and approved by national regulatory authorities in some countries.

Hepatitis B infection is caused by the Hepatitis B virus and is usually screened for by detecting HBsAg in the blood. Immunity may be discerned by detecting HBsAb, and if absent, the Hepatitis B vaccine or Twinrix® vaccine may be given.

  • The hepatitis B virus is 100 times more infectious than HIV, the virus that causes AIDS, and infects about 10 times more people than HIV worldwide.
  • Hepatitis B virus infects the liver, and more than 350 million people in the world are lifelong hepatitis B virus carriers.
  • Long-term hepatitis B virus infection causes at least one million premature deaths every year from cirrhosis of the liver or liver cancer. It is second only to tobacco as the leading cause of cancer in humans.
  • Among the Hepatitis B carriers, 25% will develop serious liver diseases, including chronic hepatitis, cirrhosis, and hepatocellular carcinoma.
  • The hepatitis B virus can be passed from an infected mother to her baby during childbirth, 1 in 20 Singaporeans are chronically infected with hepatitis B virus.
