Introduction: Pneumococcal diseases (PD) caused by include invasive PD (IPD) and non-bacteremia pneumococcal pneumonia (NBPP). Current French vaccination guidelines FOCUS on patients with underlying medical conditions (UMC) who are at a higher risk of PD. This study describes the healthcare resource utilization (HCRU) and economic burden of inpatient PD in French adults, to inform vaccination guidelines, especially among vulnerable subpopulations at increased risk of PD.

Background: Due to high costs of pneumococcal conjugate vaccines (PCV), transitioning from a two (2 + 1) to a single dose (1 + 1) primary series with a booster should be considered. This study evaluated the immune response at 18 months of age following a 1 + 1 compared to a 2 + 1 schedule of 10-valent (PCV10) and 13-valent (PCV13) vaccines.
Research Design And Methods: A single-center, open-label, randomized trial conducted in Soweto, South Africa, evaluated the immunogenicity of differing dosing schedule for PCV10 and PCV13.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.
Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.

Background: The 23-valent pneumococcal polysaccharide vaccine (PPSV23) is recommended for standalone or sequential use in the elderly in many countries to prevent pneumococcal disease, making it crucial to assess vaccine response and long-term persistence.
Purpose: We aimed to describe the trajectories of circulating antibody levels to the PPSV23 in the elderly following immunization.
Methods: Eligible individuals aged 65 to 70 years were enrolled and vaccinated with one dose of PPSV23.

Influenza and pneumococcal vaccinations play a crucial role in disease prevention among older adults and are recommended to older adults aged 60 years and over in China, but the vaccination rates are suboptimal. Behavioral spillover indicates that a change in one behavior may lead to changes in other related behaviors. Based on the Behavioral Spillover Theory, this study aimed to investigate the association between influenza vaccination history and pneumococcal vaccination intention, as well as the mediating role of negative attitudes toward general vaccination among older adults in China.
