Y59: Other and unspecified vaccines and biological substances

Y59.1: Rickettsial vaccines

The Rickettsial vaccines are used to prevent diseases caused by bacteria of the Rickettsia family. This group of bacteria can cause several severe illnesses, collectively known as Rickettsial diseases, usually transmitted through the bites of making contact with infected ticks, fleas, or mites. Common symptoms of Rickettsial diseases include fever, headache, confusion, and a rash. The disease progression can vary but often starts mild and becomes more severe without treatment. It can affect multiple body systems, including the skin, cardiovascular system, and central nervous system. Rickettsial vaccines aim to protect individuals from developing these ailments by stimulating the immune system to recognize and combat Rickettsia bacteria effectively. These vaccines are particularly important for individuals residing in or traveling to areas where such tiny vectors are prevalent.
