Purified vero cell rabies vaccine.

Action

Pharmacotherapeutic group: Purified inactivated rabies vaccine prepared on Vero Cells. For the prophylactic or post exposure immunization. Prepared using L. Pasteur 2061/Vero Rabies Strain.
Pharmacology: Bioavailability and Pharmacokinetics: The vaccines used for pre-exposure and post-exposure vaccination are the same, but the immunization schedule differs. Rabies immunoglobulin is used only for post-exposure prophylaxis. Modern vaccines of cell-culture or embryonated-egg origin are safer and more effective than the older vaccines, which were produced in brain tissue. These modern rabies vaccines are now available in major urban centres of most countries of the developing world. Rabies immunoglobulin, on the other hand, is in short supply worldwide and may not be available, even in major urban centres, in many dog rabies-infected countries.

Indications/Uses

For active immunization against rabies, both for prophylaxis and post-bite therapy with all age group of humans.
For immunization against rabies after exposure (after contact with a rabid or suspected rabid animal).
For prophylactic immunization of all high-risk individuals such as veterinarians, municipal workers, medical and paramedical personnel and zoo personnel, hunters, laboratory personnel, working with suspected rabies materials and pet owners.
