A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.
There are currently two types of pneumococcal vaccines: pneumococcal conjugate vaccine (PCV13) and pneumococcal polysaccharide vaccine (PPSV23). There are more than 90 types of pneumococcal bacteria. PCV13 protects against 13 types and PPSV23 protects against 23 types. Both vaccines provide protection against illnesses like meningitis (infection of the covering of the brain and spinal cord) and bacteremia (blood infection).
