Immunization with PspA incorporated into a poly(ethylene oxide) matrix elicits protective immunity against Streptococcus pneumoniae.

摘要

CBA/N mice were immunized with PspA in a poly(ethylene oxide) matrix to examine its ability to deliver the antigen and modulate the immune response. All mice receiving PspA in the matrix survived a lethal pneumococcal challenge and had serum anti-PspA antibody levels statistically higher than mice receiving PspA alone (P < 0.009).
