    Abstract Vaccine impact models against rotavirus disease (RD) and pneumococcal disease (PD) in low- and middle-income countries assume vaccine coverage based on other vaccines. We propose to assess the impact on severe disease cases and deaths avoided based on vaccine doses delivered by one manufacturer to Gavi-supported countries. From the number of human rotavirus vaccine (HRV) and pneumococcal polysaccharide protein D-conjugate vaccine (PHiD-CV) doses delivered, we estimated the averted burden of disease 1) in a specific year and 2) for all children vaccinated during the study period followed-up until 5 years (y) of age. Uncertainty of the estimated impact was assessed in a probabilistic sensitivity analysis using Monte-Carlo simulations to provide 95% confidence intervals. From 2009 to 2019, approximately 143 million children received HRV in 57 Gavi-supported countries, avoiding an estimated 18.7 million severe RD cases and 153,000, deaths. From 2011 to 2019, approximately 146 million children received PHiD-CV in 36 countries, avoiding an estimated 5.0 million severe PD cases and 587,000 deaths. The number of severe cases and deaths averted for all children vaccinated during the study period until 5 years of age were about 23.2 million and 190,000, respectively, for HRV, and 6.6 million and 749,000, respectively, for PHiD-CV. Models based on doses delivered help to assess the impact of vaccination, plan vaccination programs and understand public health benefits. In 2019, HRV and PHiD-CV doses delivered over a 5-y period may have, on average, averted nine severe disease cases every minute and one child death every 4 min.

    Abstract Introduction: Pneumococcal conjugate vaccine (PCV) impact studies have reported substantial reductions in the incidence of invasive pneumococcal disease (IPD) after implementation of childhood PCV programs. Heterogeneity in surveillance systems, local epidemiology and PCV programs hampers comparisons between studies. We aimed to better understand the impact of childhood PCV programs on overall IPD and serotype distribution.
    Areas covered: We analyzed the impact of PCV programs on the incidence of overall IPD, and the distribution of vaccine serotypes (VT) and non-vaccine serotypes (NVT) in children <5 years and adults ≥65 years old. We retrieved datasets from observational post-marketing studies and surveillance reports from countries with high-quality surveillance data available for at least 2 years before PCV program initiation and 3 years after higher-valent PCV implementation. We harmonized pre- and post-PCV analysis periods and assessment methods.
    Expert commentary: After introduction of pediatric PCV programs, the residual overall IPD burden in children was low and in a narrow range across countries with high vaccination coverage, irrespective of differences in PCV programs and pneumococcal epidemiology. Effects on overall IPD were more variable in the elderly. Whereas IPD was mainly due to VTs before PCV introduction, NVTs are the major contributor today in children and adults.

    Abstract Introduction: Streptococcus pneumoniae
    Areas covered: We performed a systematic literature review to analyze the frequency and clonal distribution of serotype 19A isolates in the pre- and post-PCV era worldwide providing a scientific background on the factors that influence multidrug resistance in pneumococcal isolates.
    Expert commentary: Serotype 19A IPD incidence increased in all regions following the introduction of the 7-valent PCV. The higher-valent PCVs have reduced the rates of 19A IPD isolates, but several circulating strains with diverse antibiotic resistance prevailed. Heterogeneous clonal distribution in serotype 19A was observed within countries and regions, irrespective of higher-valent PCV used. An increase of 19A isolates from pre- to post-vaccination periods were associated with frequently occurring serotype switching events and with the prevalence of multidrug resistant strains. Rational antibiotic policies must be implemented to control the emergence of resistance.
