1 Rabies biologics marketed in other countries are not included here.
2 Pre-exposure prophylaxis is indicated for specific populations who are at increased risk for rabies exposure such as veterinarians and rabies research laboratory workers.
3 Licensed by the U.S. Food and Drug Administration after development of the 2010 ACIP Rabies Guidelines.
Note HyperRab® immunoglobulin product has a different concentration compared to all other rabies immunoglobulins (including the very similarly named HyperRabS/D) – requiring lower volumes to administer the recommended dose of 20 IU/kg ; care should be taken to ensure the correct dose of immunoglobulin is administered to ensure adequate immune response.
