Abstract: Objective To provide reference for rational and safe use of pneumonia vaccines by mining and studying the adverse reaction signals of pneumonia vaccines. Methods The reporting odds ratio (ROR) and the proportional reporting ratio (PRR) were used to analyze the adverse reaction reports collected by the American Vaccine Adverse Reaction Event Reporting System (VAERS) between January 1, 2010 and December 31, 2019, while adverse reaction signals related to pneumonia vaccines were mined. Results Thirty-six ADR signals associated with 23-valent pneumonia polysaccharide vaccines were obtained using both the ROR and PRR method, seven of which were not mentioned in specifications before, and ADR with the highest signal intensity were related to leukocytosis. A total of 103 ADR signals of 13-valent pneumococcal polysaccharide conjugate vaccines were obtained using ROR, compared with 102 signals by PRR. Thirty-six of the ADR signals were not mentioned in any specifications before, and ADR with relatively high signal intensity centered on gastrointestinal diseases, infections and invasive diseases, systemic diseases, and various reactions at the administration site. Conclusion It is suggested that patients should be closely monitored for adverse reactions, especially new ADR that are not mentioned in specifications, and immediate interventions should be enforced when pneumonia vaccines are used.
