After the operation, the body will be weak, and the immunity and resistance will be seriously reduced. It takes a long time to form antibodies in the body after vaccination in COVID-19, and poor health after vaccination will affect antibody production and weaken the effect of COVID-19 vaccine.
Secondly, in order to speed up the recovery time after surgery, most of them will take drugs. Because you can't take drugs before and after vaccination in COVID-19, especially antibiotics and glucocorticoids, to prevent other adverse reactions. Therefore, patients after operation should pay attention not to take COVID-19 vaccine immediately, but to take it after a period of recovery. During the period of rehabilitation, we need to pay attention to balanced nutrition. If our physical condition permits, we need to do appropriate activities to promote the recovery of our physical condition and get COVID-19 vaccine as soon as possible.
Generally, pain, tenderness, redness and itching may appear at the injection site within 24 hours after COVID-19 vaccination, and in most cases they will disappear within 2-3 days. Transient fever and fatigue can occur after vaccination, and generally disappear without treatment in a short time.
