    The 13-valent (PCV13) and 10-valent (PCV10) pneumococcal conjugate vaccines missed non-inferiority for certain 7-valent (PCV7) serotypes in immunogenicity trials...Despite missing non-inferiority for serotypes in immunogenicity trials, higher-valent PCVs effectively suppressed these serotypes across all ages. Non-inferiority criteria from immunogenicity trials may not fully predict real-world disease impact after PCV implementation.

    Review, Journal:  Effect of pneumococcal conjugate vaccines on viral respiratory infections: a systematic literature review. (Pubmed Central) -  Sep 24, 2024   
    Limited evidence for adults was generally consistent with pediatric data. Restricting public health evaluations to confirmed pneumococcal outcomes may underestimate the full impact of PCVs.

    Journal:  Effects of PCV10 and PCV13 on pneumococcal serotype 6C disease, carriage, and antimicrobial resistance. (Pubmed Central) -  Apr 22, 2024   
    In contrast to PCV10, PCV13 vaccination consistently protected against 6C IPD and NPC in children, and provided some level of indirect protection to adults, supporting that serotype 6A but not 6B provides cross-protection to 6C. Vaccine policy makers and regulators should consider the effects of serotype 6A-containing PCVs against serotype 6C disease in their decisions.

    PNEUMOCOCCAL SEROTYPES ASSOCIATED WITH INVASIVE PNEUMOCOCCAL DISEASE AND CARRIAGE IN UK CHILDREN  (Poster Area; Board 366) -  Feb 24, 2024 - Abstract #ISPPD2024ISPPD_730;    
    These data suggest that PCV20 has the potential to substantially impact the remaining IPD burden and carriage of PCV20 serotypes in UK children. Contemporary data are needed to enable an understanding of the current contribution of PCV20 serotypes to disease and carriage.

    Despite being included in PCV13, ST03 has been evolved to be one of the leading ST. During the pandemic (2020+2021), other STs (ST6A and ST15B, both covered by PCV20) became more common.

    IMMUNOGENICITY PROFILE IN HEALTHY INFANTS ACROSS STUDIES IN THE GLOBAL 13-VALENT PNEUMOCOCCAL CONJUGATE VACCINE PEDIATRIC CLINICAL PROGRAM (Poster Area; Board 321) -  Feb 24, 2024 - Abstract #ISPPD2024ISPPD_422;    
    PCV13 licensure and subsequent introduction into national immunization programs was supported by demonstration of serotype-specific immune responses associated with functional activity, with priming for a vigorous booster response, for both the 2+1 and 3+1 schedules. Geographic and schedule-based variations in immunogenicity exist, emphasizing the need for direct comparison to a vaccine of known effectiveness in each study.

    COST-EFFECTIVENESS ANALYSIS OF PNEUMOCOCCAL CONJUGATE VACCINES IN THAILAND (Poster Area; Board 465) -  Feb 24, 2024 - Abstract #ISPPD2024ISPPD_341;    
    Estimates of direct and indirect vaccine effectiveness (VE) for the MM were derived from PCV10/PCV13 clinical effectiveness and PCV7 clinical efficacy studies, whereas the VE for DIFM was based on a real-world impact trend... Implementing a PCV10 or PCV13 NIP could prevent more PD cases in Thailand and were cost-effective compared with no vaccine, though in general PCV13 appear to be more cost-effective than PCV10.

    AOM Sp prevalence and PCV20-nonPCV13 serotype distribution were associated with PCV choice for national immunization programs Infant vaccination with PCV20 is estimated to further reduce pneumococcal disease and associated healthcare system and societal costs compared to both PCV13 and PCV15.

    7000 CHILDREN, 53 SEROTYPES AND 17 YEARS: THE STORY OF PAEDIATRIC PNEUMOCOCCAL CARRIAGE SURVEILLANCE ON ENGLAND'S SOUTH COAST (Meeting Room 1.60) -  Jan 4, 2024 - Abstract #ISPPD2024ISPPD_58;    
    Methods The study started during the roll-out of PCV7 in 2006...Finally, since 2009/10 the greatest proportion of MDR isolates (21.1%) was serotype 15A (notably ST63), although MDR frequency has remained low overall. Conclusions Ongoing pneumococcal carriage surveillance highlights emerging trends in serotype epidemiology that can be used to guide vaccine design and implementation.

    MOLECULAR STRATEGIES REVEAL PERSISTENCE OF 13 VALENT PNEUMOCOCCAL CONJUGATE VACCINE (PCV) SEROTYPES IN HIGHLY IMMUNIZED CHILDREN (Meeting Room 1.60) -  Jan 4, 2024 - Abstract #ISPPD2024ISPPD_56;    
    Background Studies of nasopharyngeal (NP) colonization in Massachusetts' children following the introduction of PCV7 reported declining prevalence of vaccine serotypes (VST), and increases in 6C, 7F, and 19A carriage...Conclusions Our results support the hypothesis that VSTs persist in immunized pediatric populations at densities below those detectable by culture. Our results are consistent with results from challenge studies reporting that molecular detection was more sensitive than culture methods in PCV13 immunized adults.

    This study highlights that healthcare workers may act as unrecognized reservoirs of pneumococcus in the population. Despite long-standing PCV7 and PCV13 pediatric immunization programs, vaccine serotypes continue to be prevalent among an adult population.

    Despite long-standing PCV7 and PCV13 pediatric immunization programs, vaccine serotypes continue to be prevalent among an adult population. Robust ongoing surveillance networks are critical for identifying emerging serotypes and development of next-generation vaccine formulations.

    Journal:  Ten year public health impact of 13-valent pneumococcal conjugate vaccination in infants: A modelling analysis. (Pubmed Central) -  Apr 28, 2021   
    A higher valent PCV13 replaced PCV7 in late 2009...PCV13 vaccination was estimated to have prevented 175.2 million cases of all pneumococcal diseases and 624,904 deaths globally between 2010 and 2019. These results demonstrate the substantial public health impact of PCV13 and highlight the importance of increasing the global reach of PCV programs.

    [VIRTUAL] Twenty-year impact of Pneumococcal Conjugate Vaccines (PCV) on the burden of invasive pneumococcal disease in US children less than 5 years of age () -  Aug 14, 2020 - Abstract #IDWeek2020IDWEEK_2181;    
    Background: Clinical trials of PCV7 demonstrate significant reductions in vaccine-type (VT) invasive pneumococcal disease (IPD), clinically diagnosed pneumonia in children less than 5 years of age and VT acute otitis media in children < 2 years of age... The substantial public health impact of PCVs over the last two decades, as measured in cases and deaths averted in children less than 5 years, re-enforces the important role vaccines play in reducing the burden of serious disease in children.
