Core Viewpoint - The release of the "Expert Consensus on Health Promotion Strategies for Adult Vaccination in China" emphasizes the necessity and health value of adult vaccination, particularly highlighting the importance of influenza vaccination in reducing disease incidence and healthcare burden [1][2]. Group 1: Importance of Adult Vaccination - The consensus identifies vaccination as the most economical and effective public health measure for preventing and controlling infectious diseases, which can reduce the incidence of various infectious diseases and some chronic diseases, as well as the risks of severe cases and mortality [1]. - Seasonal influenza vaccination can reduce hospitalization rates by 45% and mortality rates by 38% among elderly diabetic patients, and is associated with a decrease in cardiovascular mortality risk [2]. Group 2: Current Challenges - The public's awareness of the benefits of vaccination in preventing infections and reducing severe cases and mortality is low, and there exists a phenomenon of "vaccine hesitancy" among healthcare professionals [2]. - The current immunization program in China primarily focuses on children, with adult vaccination services largely dependent on medical institutions, resulting in a very low coverage rate for adult vaccinations [2].

Group 2: Impact of Influenza Vaccination - Seasonal influenza vaccination can reduce hospitalization rates and mortality rates by 45% and 38% respectively for elderly diabetic patients, and is associated with a decrease in cardiovascular mortality risk [2]. - Vaccination during hospitalization for acute heart failure improves survival rates and reduces the risk of readmission within the following 12 months [2]. Group 3: Current Challenges and Recommendations - The current immunization plan in China focuses primarily on children, resulting in low coverage rates for adult vaccinations [3]. - The consensus recommends expanding adult immunization channels and improving service systems, with some regions already establishing independent adult vaccination clinics [3]. - Various regions have implemented government procurement for free influenza vaccinations for the elderly, and some areas have included non-immunization plan vaccines in personal medical insurance accounts to alleviate the burden on the public [3].
