Study population: Three recommended groups for influenza vaccination in China, including children (aged between 6 to 59 months), the elderly (aged 60 years old or above), and adult patients with chronic diseases (aged below 60 years old); Vaccination and health care personnel in each study site.

Brief summary: This trial focuses on influenza vaccination among three recommended groups in China. Data concerning the economic burden of influenza-like illness (ILI), vaccine hesitancy, discrete choice experiment, immunization records and willingness to pay for vaccines will be collected via questionnaires, and the financing strategies of influenza vaccines in China will be further analyzed. Besides, the knowledge, attitude/belief and practice (KAP) of medical staff will also be asked in a supplementary questionnaire.

Detailed description: This trial focuses on influenza vaccination among three recommended groups in China, including children (aged between 6 to 59 months), the elderly (aged 60 years old or above), and adult patients with chronic diseases (aged below 60 years old).

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.

Eligibility criteria: Inclusion Criteria:

* (For children group) children aged between 6 to 59 months.
* (For the elderly group) the elderly aged 60 years old or above.

* (For medical staff) general practitioners and vaccination staff.
* Interviewees with informed consent.

Exclusion Criteria:

* Those cannot be surveyed for physical reasons.
