Under normal circumstances, patients can take the vaccination about 1 week after recovering from the cold, because the immunity of the patient will be reduced in the short term after the cold, and if the vaccination is taken too early, there is a possibility that adverse reactions to the vaccine may occur, resulting in serious adverse reactions to the vaccine. For example, it may lead to fever and diarrhea, and may also affect the effectiveness of the vaccine, resulting in poor vaccine results. Therefore, it is recommended that the vaccination be administered only after the patient has recovered from the cold and the body has fully recovered, so that adverse reactions can be avoided. It takes about 1 week for the body to fully recover from a cold, so patients can get vaccinated 1 week after they recover from the cold, and they should pay attention to the change in body temperature after vaccination, and go to the hospital promptly if there are symptoms of high fever.
