The static C refers to the injection of human immunoglobulin, which is usually given two weeks after the injection of human immunoglobulin, and then the new coronavirus vaccine can be given. Human immunoglobulin injection is actually a vaccine, and according to the Technical Guidelines for Neocoronavirus Vaccination, it is recommended that the interval between the Neocoronavirus vaccine and other vaccines should be at least two weeks, because the Neocoronavirus vaccine is a new vaccine. Therefore, individuals should wait two weeks after receiving human immunoglobulin before receiving the new coronavirus vaccine. The new crown vaccine is of great importance in the prevention and control of new crown outbreaks today. Therefore, men and women, young and old, should be vaccinated with the new crown vaccine in a timely and orderly manner when it is not contraindicated, so as to not only maintain their health, but also to help control the epidemic and maintain the stability of the society. In addition, individuals should pay attention to observation after vaccination and consult their physicians promptly if they have any physical abnormalities.
