Health Economic Evaluation of Influenza and Pneumococcal Vaccination in COPD Patients

Starting soon · Phase 4

Conditions studied: Influenza and Pneumonia

In brief

This is a multicenter, open-label, blank-controlled clinical trial to evaluate the impact of influenza vaccination and pneumococcal vaccination on disease progression and medical burden in COPD patients aged 45-80 years, as well as the safety and immunogenicity of vaccination. COPD patients aged 45-80 years are recruited. On the basis of informed consent and voluntary participation, influenza and pneumococcal vaccination are carried out. At each site, towns/subdistricts will be randomly assigned as clusters to one of four groups in a 2:2:2:1 ratio: influenza vaccine group, pneumonia vaccine group, combined vaccination group, and blank control group. Follow-up lasts 12 months from informed consent. For the immunogenicity subgroup, during the period from September 1, 2026 to October 31, 2026, the first 50 participants enrolled for influenza vaccination at each site (Dongtai City and Wujin District) are included in the influenza vaccine immunogenicity subgroup, and the first 50 participants enrolled for pneumococcal vaccination at each site are included in the pneumococcal vaccine immunogenicity subgroup, with the two subgroups serving as mutual controls. Blood samples (5ml each time) are collected before vaccination and at 1 month, 6 months, and 12 months after vaccination.
