Design outcomes

Primary

MeasureTime frame
Main Objective: To determine the rate of nasal colonization by different pneumococcal serotypes in HIV-positive adults, in relation to baseline antibody titers at T0; to define serological response after 2 doses of PCV13 vaccine (booster dose after 8 weeks) in HIV+ adults; to evaluate the effect of 2 doses PCV13 vaccine in terms of nasal pneumococcal carriage and occurrence of invasive pneumococcal diseases.;Secondary Objective: To determine pneumococcal serotypes and chemosusceptibility to different antibiotic and to evaluate the prevalence of multiresistant strains; to evaluate molecular epidemiology of pneumococcal isolates.;Primary end point(s): to define serological response after 2 doses of PCV13 vaccine (booster dose after 8 weeks) in HIV+ adults;Timepoint(s) of evaluation of this end point: 1 year

Secondary

MeasureTime frame
Secondary end point(s): To determine the rate of nasal colonization by different pneumococcal serotypes in HIV-positive adults, in relation to baseline antibody titers at T0; to evaluate the effect of 2 doses PCV13 vaccine in terms of nasal pneumococcal carriage and occurrence of invasive pneumococcal diseases; to determine chemosusceptibility to different antibiotic and to evaluate the prevalence of multiresistant strains to evaluate molecular epidemiology of pneumococcal isolates.;Timepoint(s) of evaluation of this end point: 2 years
