Abstract
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.
期刊介绍：
(formerly Human Vaccines; issn 1554-8619)
Vaccine research and development is extending its reach beyond the prevention of bacterial or viral diseases. There are experimental vaccines for immunotherapeutic purposes and for applications outside of infectious diseases, in diverse fields such as cancer, autoimmunity, allergy, Alzheimer’s and addiction. Many of these vaccines and immunotherapeutics should become available in the next two decades, with consequent benefit for human health. Continued advancement in this field will benefit from a forum that can (A) help to promote interest by keeping investigators updated, and (B) enable an exchange of ideas regarding the latest progress in the many topics pertaining to vaccines and immunotherapeutics.
Human Vaccines & Immunotherapeutics provides such a forum. It is published monthly in a format that is accessible to a wide international audience in the academic, industrial and public sectors.
