Influenza is a highly-infected disease that can cause severe illnesses and even deaths [In contrast, the coverage of influenza vaccination in China remains relatively low-only 3.8% of the older participants were vaccinated in a national survey study during the 2018–2019 flu season [In 2009, with the implementation of the national medical reform, China launched the national basic public health service program, which required primary healthcare facilities to deliver defined public health services, including vaccination services, physical check-ups, and health management to older residents. [Evidence has shown that providing influenza vaccination free of charge might improve vaccination coverage [The goal of this study had two folds. First, this study aimed to evaluate whether PCP could improve influenza vaccination among older adults. Second, this study compared the knowledge, attitude, and practice level of influenza vaccination among older adults before and after the free influenza vaccination program implementation in Shenzhen, China. Findings from this study can provide valuable insights regarding health policies on influenza vaccine uptakes among older adults in other regions and contribute efforts to improving influenza vaccination coverage.
