Under normal circumstances, patients can receive the vaccination after 1 week of being completely well from the cold. Patients who have recovered from a cold within 1 week may have adverse reactions, such as fever and diarrhea, if they receive the vaccination too early. At this time, the patient’s immunity is relatively low, so if the vaccination is given, it may affect the effectiveness of the vaccination. Patients should also not be vaccinated too long apart after recovering from a cold, as the effectiveness of the vaccine may be reduced if the time between two vaccinations is too long. It is clinically recommended that patients go for vaccination about 1 week after they have fully recovered from the cold, so as not to cause patients to fail to achieve effective preventive effects after vaccination. Patients should make sure that they are in full health when they get the vaccination. If they have symptoms such as fever, cough or diarrhea, they should postpone the vaccination.
