Immunogenicity and Safety of 13-valent Pneumococcal Conjugate Vaccine Among HIV-infected Adults

Summary

HIV-infected patients are 30- to 100-fold more susceptible to invasive pneumococcal diseases. Pneumococcal vaccination is the best way to decrease the large pneumococcal disease burden, but the optimal timing of vaccination is still unclear. HIV-infected subjects aged ≥ 18 years were recruited and divided into two age-matched groups: group 1 (subjects with CD4 T-cell counts ≥350 cells/µL) and group 2 (subjects with CD4 T-cell counts \<350 cells/µL). Multiplex opsonophagocytic killing assay was used to compare immunogenicity after the immunization of 13-valent pneumococcal conjugate vaccine (PCV13).
