Appointments for vaccine booster vaccinations vary slightly from place to place, and can be made in two ways: online through public numbers, websites, etc. and offline through hospitals and health centers. It is more common to apply through health epidemic prevention departments, such as township health centers, street health service centers, and CDCs, which will open up free vaccinations to the public based on vaccine stockpiles. It is sufficient to bring the vaccinator’s identity document and register for an appointment at such organizations. In addition, some areas have also opened online appointment channels, patients can consult the local CDC and other departments by phone, and follow the prompts to make an appointment on WeChat public number, website and so on. However, there is a limit to the number of appointments that can be made online, so in order to avoid failing to make an appointment, patients need to pay attention to it in a timely manner. The day before the booster vaccination, you should pay attention to rest and keep your body in the best condition. Don’t drink alcohol and don’t eat spicy and stimulating food before the vaccination. After the inoculation is completed, you need to stay on site for 30 minutes, and keep the injection site dry and pay attention to personal hygiene on the day of inoculation.
