Production of opsonins that facilitate phagocytosis of Streptococcus pneumoniae by human alveolar macrophages or neutrophils after vaccination with pneumococcal polysaccharide.

Vaccination with pneumococcal polysaccharide enhanced the opsonic capabilities of serum facilitating phagocytosis of type 7F Streptococcus pneumoniae by human alveolar macrophages of neutrophils. In contrast to nonimmune serum, opsonization of S. pneumoniae in immune serum occurred rapidly and did not require complement components. In addition, immune serum greatly enhanced the rate and amount of uptake of S. pneumoniae by alveolar macrophages or neutrophils.
