Before vaccination, it is generally important to understand vaccine information, confirm your health status, wear loose clothing, avoid getting vaccinated on an empty stomach, and bring necessary documents. The details are as follows:

1. Understand vaccine information: Learn in advance from reliable sources about the vaccine's name, purpose, vaccination schedule, and possible side effects. Being well-informed helps reduce anxiety during vaccination.

2. Confirm your health status: Check your health condition before vaccination. If you have a fever, cold, acute illness, or an unstable chronic condition, postpone vaccination until you recover.

3. Wear loose clothing: Wear comfortable, easy-to-remove clothes on the day of vaccination to expose the injection site easily, reducing operational difficulty and time, and improving efficiency.

4. Avoid fasting: Getting vaccinated on an empty stomach may cause low blood sugar, leading to dizziness or palpitations. Eat a light meal beforehand to maintain good physical condition.

5. Bring necessary documents: Carry required identification such as your ID card and vaccination record to allow staff to verify your identity and ensure accurate documentation.

After vaccination, stay at the clinic for 30 minutes of observation to monitor for any adverse reactions. Once home, rest adequately, keep the injection site clean and dry, and avoid strenuous activities or overexertion.
