Abstract Background: HIV-infected children are at a higher risk of Invasive Pneumococcal Disease (IPD) and its mortality, even in the era of antiretroviral therapy. Therefore, an effective vaccination strategy would be beneficial. To investigate the effectiveness of Pneumococcal Conjugate Vaccination (PCV) against IPD among HIV-Infected and HIV-Uninfected Children through a systematic review and meta-analysis. Methods: Observational studies and randomized trials on 7 years old or older children were searched in the Cochrane Library, Web of Science core collection, Embase, Medline/PubMed, and Google Scholar. Critical appraisal was done using the Cochrane risk of bias tool and the Newcastle-Ottawa quality assessment form. Effectiveness and efficacy of at least one dose of PCV was investigated among children with and without HIV considering subgroups of pneumococcal serotypes. We meta-analyzed the effect sizes using random-effects modeling. Results: Efficacy of PCV was estimated as 45.0% (31.2, 56.1) and 52.6% (25.7, 69.8) among HIV-infected and HIV-uninfected children, respectively. Effectiveness of PCV among HIV-infected children as -6.2% (-67.6, 32.7) was significantly lower than HIV-uninfected children 65.1% (47.3, 76.9). Effectiveness of PCV among HIV-infected children for IPDs caused by vaccine serotypes was estimated as 7.7(-66.7, 48.9), and for IPDs caused by non-vaccine serotypes was estimated as -402.8(-1856, -29.2). Conclusion: Unlike the evidence on the efficacy of PCV against IPD among both of HIV-infected and HIV-uninfected children, its effectiveness against IPD among HIV-infected children is much less limited. Review Registration The study protocol was registered at PROSPERO (registration ID: CRD42018108187).

Abstract Background Two new pneumococcal conjugate vaccines (PCVs), PCV15 and PCV20, are anticipated to be licensed for use in U.S. adults in 2021. To help inform the U.S. Advisory Committee on Immunization Practices’ discussions on pneumococcal vaccine use among adults, we conducted a systematic review and meta-analysis. We specifically looked at efficacy or effectiveness of PCV13 and pneumococcal polysaccharide vaccine (PPSV23) against invasive pneumococcal disease (IPD) in adults. Methods We conducted a search of English literature published from 1998 – February 2021 on PCV13 and PPSV23 efficacy or effectiveness studies using eight major databases. Studies targeting adults with immunocompromising conditions were excluded. Title and abstract screening of identified studies and data abstraction were performed by two reviewers. Results were stratified by vaccine product, outcome evaluated (vaccine type (VT) or all IPD), study design, and effect measure. Random effects models were used to pool estimates by stratum. Results Of 3,422 citations reviewed, we identified 26 IPD studies; 4 on PCV13, 22 on PPSV23, 18 with all IPD, and 17 with VT-IPD (Table) as an outcome. Only one randomized-controlled trial (RCT) was identified for PCV13 with an efficacy of 52% (95% CI: 22%, 77%) against all IPD and 75% (95% CI: 41%, 91%) against VT-IPD. A pooled vaccine effectiveness (VE) estimate from three observational studies evaluating PCV13 was 56% (95% CI: 32%, 71%; I2 =12.8) against VT-IPD. Two RCTs evaluating PPSV23 reported efficacies against all IPD ranging between 79-86%; an additional RCT reported no IPD cases during RCT. Vaccine effectiveness estimates from 14 observational studies evaluating PPSV23 ranged between 29-76% against all IPD. Pooled VE estimates from 12 observational studies showed PPSV23 effectiveness against VT-IPD was 38% (95% CI: 28% to 46%; I2 =40.8). Table. Efficacy and effectiveness studies against vaccine-type invasive pneumococcal disease Conclusion Evidence suggests both pneumococcal vaccines are effective against VT-IPD in adults. Given that PCV15 and PCV20 are expected to be licensed based on immunogenicity data and no clinical efficacy data are available for these new vaccines, the findings from this review will help inform policy discussions on use of the new PCVs among adults.

AbstractRisk factors associated with mortality in invasive pneumococcal disease remain unclear. The present work is a meta-analysis of studies that enrolled only patients with invasive pneumococcal disease and reported on mortality. Potentially eligible reports were identified from PubMed, CHAHL, and Web of Science, comprising 26 reports in total. Overall mortality for invasive pneumococcal disease was reported as 20.8% (95% confidence interval (CI) 17.5–24%). Factors associated with mortality were age (odds ratio (OR) 3.04, 95% CI 2.5–3.68), nursing home (OR 1.62, 95% CI 1.13–2.32), nosocomial infection (OR 2.10, 95% CI 1.52–2.89), septic shock (OR 13.35, 95% CI 4.54–39.31), underlying chronic diseases (OR 2.34, 95% CI 1.78–3.09), solid organ tumor (OR 5.34, 95% CI 2.07–13.74), immunosuppressed status (OR 1.67, 95% CI 1.31–2.14), and alcohol abuse (OR 3.14, 95% CI 2.13–4.64). Mortality rates with invasive pneumococcal disease remained high, and these findings may help clinicians provide appropriate initial treatment for this disease.

Abstract Background The 13-valent pneumococcal vaccine (PCV13) was introduced for US children in 2010 and for immunocompromised adults ≥19 years old in series with the 23-valent polysaccharide vaccine (PPSV23) in 2012. We evaluated PCV13 indirect effects on invasive pneumococcal disease (IPD) among adults with and without PCV13 indications. Methods Using Active Bacterial Core surveillance and the National Health Survey, using Active Bacterial Core surveillance and the National Health Interview Survey, we estimated and compared IPD incidence in 2013–2014 and 2007–2008, by age and serotype group (PCV13, PPSV23-unique, or nonvaccine types [NVTs]), among adults with and without PCV13 indications. Results IPD incidence declined among all adults. Among adults 19–64 years, PCV13-type IPD declined 57% (95% confidence interval [CI], −68% to −43%) in adults with immunocompromising conditions (indication for PCV13 use), 57% (95% CI, −62% to –52%) in immunocompetent adults with chronic medical conditions (CMCs, indications for PPSV23 use alone), and 74% (95% CI, −78% to −70%) in adults with neither vaccine indication. Among adults aged ≥65 years, PCV13-type IPD decreased 68% (95% CI, −76% to −60%) in those with immunocompromising conditions, 68% (95% CI, −72% to −63%) in those with CMCs, and 71% (95% CI, −77% to −64%) in healthy adults. PPSV23-unique types increased in adults 19‒64 years with CMCs, and NVTs did not change among adults with or without PCV13 indications. From 2013 to 2014, non-PCV13 serotypes accounted for 80% of IPD. Conclusions IPD incidence among US adults declined after PCV13 introduction in children. Similar reductions in PCV13-type IPD in those with and without PCV13 indications suggest that observed benefits are largely due to indirect effects from pediatric PCV13 use rather than direct use among adults.

Mortality rates with invasive pneumococcal disease remained high, and these findings may help clinicians provide appropriate initial treatment for this disease.Key points: The overall mortality rate from IPD has remained high, at 20.8% and older age, septic shock, immunosuppressed status, underlying chronic diseases, solid organ tumor, alcohol abuse, nursing home, and nosocomial infection were prognostic factors for mortality from IPD.
