Vaccination, or vaccination, is the most economical and effective measure to prevent and control infectious diseases and helps protect public health. Since vaccination services are part of the basic public health service program, vaccination can be done at primary health care institutions such as township health centers, community health service centers, village health offices or community health service stations. Since policies and conditions vary slightly from place to place, patients can choose the appropriate medical institution for vaccination according to their personal conditions. Vaccination can effectively prevent and control the spread of infectious diseases, but it is not absolute, and most vaccines have a protection rate of >80%. Therefore, before vaccination, patients should first make a good assessment of their own situation and cooperate with their doctors to provide information about their medical and genetic history to reduce the possibility of adverse reactions. It is usually necessary to observe the patient for 30 minutes after vaccination at an appropriate medical facility to ensure that the patient has no serious reactions before leaving. And patients should be vaccinated as required according to the interval of different vaccines and try to avoid excessive fatigue or spicy and stimulating diet during vaccination. In addition, during the New Crown epidemic, patients who need to receive the New Crown vaccine can usually go to their nearest vaccination unit. If patients are unable to receive the vaccination for personal reasons, they can also make an appointment in advance to receive the vaccination at another medical institution upon request of the local health administration, CDC or vaccination unit.
