Pneumococcal conjugate vaccine (PCV)

The Pneumococcal conjugate vaccine (PCV) is a shot that protects against pneumococcal disease, caused by bacteria called Streptococcus pneumoniae. These bacteria can lead to serious infections such as pneumonia, meningitis, and bloodstream infections, especially in young children, older adults, and people with weakened immune systems. The vaccine works by helping the immune system recognize and fight these bacteria more effectively. It is usually given in a series of doses during early childhood, with some booster shots later in life, reducing the risk of severe illness and preventing outbreaks.
