Vaccination is generally not recommended the day after you get well from a cold, and it is recommended to wait for 3-7 days after you get well from a cold before vaccination. The immunity of the body will be reduced when the body and brain functions are damaged by the cold, and the body functions need a recovery period after the cold symptoms are recovered. This is because the vaccine itself is a small amount or low activity virus, and a healthy person can be vaccinated without being infected and having antibodies, but if the body is not in a healthy state or the resistance is weak, it may not be able to resist and induce disease instead. In addition, if you have a recurring cold and fever at this time, it is easy to confuse it with the adverse reaction of fever after vaccination, which may interfere with the disease and delay the treatment. Therefore, you should explain your illness or disease history to your doctor before vaccination, and try to get vaccinated when you are in good health and meet the conditions for vaccination.
