However, there is limited information on the efficacy of vaccination among patients undergoing dialysis or patients with chronic kidney disease (CKD). The objective of this review is to assess the effectiveness of vaccination within dialysis and CKD patient populations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>This will be a systematic review of studies assessing the effectiveness of vaccination among CKD and dialysis patients. Relevant studies will be identified using MEDLINE, Embase, Scopus and Cochrane Library. All searches will be conducted from database inception to October 2025. Only observational studies such as cohort, prospective, retrospective and cross-sectional studies will be included. Data pertaining to patient outcomes and study design will be extracted. A narrative synthesis will be conducted as well as a meta-analysis if data permitting this analysis is extracted from included studies.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Since data collection will be conducted by examining existing studies, no ethical approval or consent will be required.
