  • For intradermal route, four doses should be administered 2 injections of 0.1 ml at 2 different sites as per the updated thai red cross regimen (2-2-2-0-2) as given above.
  • In those previously immunized by complete vaccination schedule (pre or post exposure prophylaxis) 2 doses of 1ml given by intramuscular route or 2 doses of 0.1 ml by intradermal route on day 0 and 3 are recommended.
  • In cases of category 3 exposures and of category 2 exposure in immunodeficient patients, human rabies immunoglobulin or equine rabies immunoglobulin should be given with Rabivax S vaccine.
  • If rabies immunoglobulin is not available at the time of first vaccination, it must be administered no later than 7 days after the first vaccination since later administered would result in interference with immune response of the vaccine

Post exposure prophylaxis

For Pre exposure prophylaxis following schedule is used for the injection.

  • Periodic booster injectios are recommended as an extra precaution only for people whose occupation puts them at continual or frequent risk of exposure.
  • For people who are potentially at risk of laboratory exposure to high concentrations of live rabies virus, antibody testing should be done every 6 monthly.
  • Those professionals who are not continual risk of exposure through their activities, should have serological monitoring every 2 years. Vaccine induced immunity persists in most cases for years, a booster should be administered if rabies virus neutralizing antibody titres fall to < 0.5 IU/ml.
