PEP (Post-exposure prophylaxis)

Post-exposure prophylaxis (PEP) is a medical treatment started shortly after a potential exposure to a virus, such as rabies or HIV, to prevent infection. It typically involves taking specific medications or vaccines within a limited time frame—usually within hours or days—after the exposure. PEP aims to boost the body’s defenses before the virus can establish a foothold. While effective when administered promptly, it’s not a guarantee, so seeking immediate medical advice after exposure to dangerous pathogens is essential.
