Pneumococcal Polysaccharide Vaccine (PPSV23) is available for free in some Chinese cities for elderly patients and those with comorbidities. However, there is a lack of studies summarizing its preventive effect specifically in Chinese adults. This review aims to discuss the epidemiology of pneumococcal disease, coverage and effectiveness of PPSV23 vaccination, elderly individuals and patients with comorbidities, coadministration of PPSV23 vaccine with other vaccines, and future directions for its use in China. It was found that the PPSV23 vaccination rate among the elderly ranged from 1.2% to 42.1% depending on location, with an effectiveness of 9.34%(95%CI: 2.05%, 16.62%) to 57.7%(95%CI: 20.7%, 77.5%). There is a need to raise awareness of pneumococcal disease and its prevention, especially in China. To better manage pneumococcal disease in China, developing new vaccines for common serotypes and continuously monitoring serotype distribution associated with the disease is also needed.

Background: SLE has increased risk of invasive pneumococcal disease due to immune dysregulation and immunosuppression. European Alliance of Associations for Rheumatology recommendations suggest sequential vaccination with conjugate vaccine, followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23). However, data on immunogenicity of sequential vaccination in SLE are limited.

Background: The 23-valent pneumococcal polysaccharide vaccine reduces the risk of pneumonia among adults by 38% to 46%. However, only a few older adults in resource-limited areas of China have received the pneumococcal vaccination. Pay-it-forward is a social innovation that offers participants free or subsidized health services and a community-engaged message, with an opportunity to donate to support subsequent recipients.

Invasive pneumococcal disease presents a threat to humankind, predominantly affecting children and the elderly. Despite the availability of high-valency pneumococcal polysaccharide vaccine of PPSV23 (PNEUMOVAX 23) and conjugate vaccines such as VAXNEUVANCE and PREVNAR 20, nonvaccine serotypes continue to contribute to higher mortality rates. The characterization of nonvaccine serotypes is becoming increasingly crucial considering an increase in their prevalence.

Background: Waning immunity from childhood vaccines can be more profound in pediatric patients following chemo/immunotherapy. Moreover, childhood cancer survivors (CCS) are at significantly increased risk for life-threatening infections. We implemented an institutional standard of practice (SOP) to assess immune reconstitution and provide recommendations for re-vaccination for non-transplant CCS.
