PrtA immunization failed to protect mice against blood propagation of S. pneumoniae. S. pneumoniae D39 cells were intravenously administered to the immunized group or adjuvant control group (n = 6 in each group). a The bacterial load in the blood was monitored on days 1, 2, and 3 post-infection. n = 6; *p < 0.05; Mann–Whitney test. b The survival rate was monitored after pneumococcus infection. Mice administered with PPSV23 were used as the positive control. **p < 0.01; Log-rank test
