Rabies Vaccine Human IP is a vaccine used to prevent rabies, a viral disease that affects the central nervous system and is transmitted to humans through the bite or scratch of infected animals, such as dogs, bats, raccoons, and other mammals. Rabies is a deadly disease, but it is entirely preventable through vaccination and post-exposure prophylaxis (PEP) after a potential exposure to the virus. Rabies Vaccine Human IP works by stimulating the body's immune system to produce antibodies against the rabies virus. In the event of exposure to the virus, the pre-existing antibodies help to neutralize and prevent the virus from spreading in the body.
