بريفينار 13 سرنجة معبأة حقن عضل

Prevenar 13 is a pneumococcal conjugate vaccine used to protect against invasive diseases caused by Streptococcus pneumoniae. It contains purified capsular polysaccharides from 13 pneumococcal serotypes, each conjugated to a carrier protein to enhance the immune response. After intramuscular injection, the vaccine stimulates the production of specific antibodies and immunological memory. This immune response helps prevent serious infections such as pneumonia, meningitis, and bacteremia caused by the covered serotypes.
