Primary Outcome Measures

Name	Time	Method
Acceptance of vaccines	Day 14	Vaccine acceptance was evaluated based on responses to the question, 'Based on your actual situation, please choose the extent of your willingness to get vaccinated.' The response options were: Absolutely refuse, Refuse but uncertain about the future, Have not considered it yet, Accept but still considering, and Completely willing. Vaccine acceptance was considered if the participant selected 'Completely willing.

Secondary Outcome Measures

Name	Time	Method
Hesitancy of vaccination	Day 14	The Vaccine Hesitancy Scale was developed based on the "3Cs" model (confidence, complacency, and convenience) by the SAGE Working Group on Vaccine Hesitancy, encompassing three aspects: confidence, complacency, and convenience. It utilizes a Likert 5-point scale (Strongly Disagree, Disagree, Neutral, Agree, Strongly Agree) for scoring. For the complacency dimension, aspect, scoring is reversed with "Strongly Agree" to "Strongly Disagree" rated as 5 to 1 points, respectively. In contrast, other items follow the standard scoring, where "Strongly Agree" to "Strongly Disagree" are scored from 1 to 5 points. Confidence is measured by perceived vaccine safety and efficacy. Complacency is assessed through perceived necessity of the vaccine and the severity of the preventable diseases. Convenience is evaluated by the perceived ease of transportation and appointment scheduling.
