Pneumococcus (Prevnar, PCV-13)

The “Pneumococcus” bacteria is the most common cause of pneumonia, ear, sinus, and bloodstream infections at all ages. Pneumococcus has become the leading cause of meningitis in both children and adults. While pneumococcus can be treated with antibiotics, some strains are learning to resist most antibiotics – which can turn this into a difficult-to-treat and potentially life threatening condition. The percentage of pneumococci resistant to antibiotics has been steadily rising for the past 15 years throughout the world.

The PCV-13 vaccine protects against the 13 most common subtypes of pneumococcus. The main side effects of PCV-13 are redness and swelling at the site of injection. Less often a low grade fever can also occur.
