How to reconstitute Rabipur vaccine?

Sterile water available with the freeze dried powder is first mixed with freeze dried powder. It is agitated gently for some time. Then the constituents are mixed evenly. When the mixture is made even and looks transparent should be sucked back in to the syringe. The reconstituted mixture should be used as soon as possible after reconstitution to retain the potency of the vaccine.

How is Rabipur vaccine given?

Rabipur vaccine is given by injection. In small children it is given on thigh anterolateral aspect. In adolescents and adult it can be given in the deltoid muscle. The injection can be given by intradermal route. Intradermal route needs less dose and efficacy almost similar to intramuscular route. All the safety injection precautions are to be taken while injection. The disposables are discarded as per the biomedical waste management protocols. The expired vaccine should not be used and discarded as per biomedical waste management protocol to protect the environment.

What is schedule for Rabipur vaccine?

For post exposure prophylaxis following schedule is recommended for the injection. The need of Rabieshield vaccine together depends upon the category of bite wound.

  • 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 injections 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 professional 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.
