According to the Technical Guideline for Vaccination with New Coronavirus (First Edition) issued by the Health Care Commission, if hepatitis B vaccination has been completed, an interval of more than 14 days is required before the new coronavirus vaccine can be administered. The 2-week interval between the new crown vaccine and other vaccines can, on the one hand, distinguish adverse reactions after vaccination and, on the other hand, reduce the risk of possible interactions between the two vaccines. For hepatitis B vaccine, HPV vaccine, etc., an interval of 14 days or more between vaccination and New Crown vaccine is required. However, in the case of animal bites and trauma, rabies vaccine, tetanus vaccine and immunoglobulin are required, because these vaccinations are urgent and failure to receive them in time may affect the patient’s life and health. In addition to the need to receive the new crown vaccine more than 14 days after the completion of the hepatitis B vaccination, it should also be noted that some people should also be cautious about receiving the new crown vaccine, such as those who are allergic to the components of the vaccine and women during pregnancy. If some patients have symptoms such as fever or diarrhea, they should wait until their symptoms have subsided before receiving the vaccination. Patients with chronic diseases in acute exacerbation or serious chronic diseases that cannot be controlled should also wait until the disease is under control before vaccination.
