REVAXIS is an inactivated vaccine designed to provide immunization against three serious diseases: diphtheria, tetanus, and poliomyelitis (polio). It is typically administered as an injection and is used as a booster vaccine in individuals who have previously been vaccinated against these diseases. The vaccine works by stimulating the body's immune system to produce antibodies against the toxins produced by the bacteria responsible for diphtheria and tetanus, as well as against the poliovirus, thereby providing protection against these infections. REVAXIS is commonly used in booster vaccination programs and is suitable for use in both adults and children, according to the specific guidelines and recommendations of health authorities.
