Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The questionnaires will collect data on the economic burden of influenza-like illness (ILI), vaccine hesitancy, discrete choice experiment, immunization records and willingness to pay for vaccines, and the financing strategies of influenza vaccines in China will be further analyzed accordingly.
Besides the three recommended groups, vaccination and health care personnel will also be asked about their knowledge, attitude/belief and practice (KAP) in a supplementary questionnaire.
