Who Gets What Type of Pneumococcal Vaccine?

Pneumococcal conjugate and pneumococcal polysaccharide vaccines are both recommended in adults at highest risk for invasive pneumococcal disease. In these adults, the pneumococcal conjugate vaccine should be administered at least 8 weeks before the pneumococcal polysaccharide vaccine. This is the preferred order of vaccination. However, patients with indications for both vaccines who have previously received the pneumococcal polysaccharide vaccine may receive the pneumococcal conjugate vaccine 1 year after the polysaccharide vaccine.

Both the pneumococcal conjugate and pneumococcal polysaccharide vaccines have specific indications in adults and children. If possible, pneumococcal conjugate and pneumococcal polysaccharide vaccines should be given before immune suppression, splenectomy, and cochlear implantation.
