You can’t get vaccinated by taking anti-inflammatory drugs, mainly because vaccination after taking anti-inflammatory drugs may affect the effect of vaccines and cannot achieve the purpose of disease prevention. There are several other reasons why you cannot get vaccinated by taking anti-inflammatory drugs: 1. Anti-inflammatory drugs have a certain bactericidal effect on the body after entering the body, which may have no effect on inactivated vaccines, but if you take anti-inflammatory drugs and then get live attenuated vaccines, such as live attenuated influenza vaccine, the anti-inflammatory drugs may interfere with the immune response of the vaccine, thus affecting the effectiveness of the vaccine, and may even lead to vaccination failure. 2. If the body has fever while taking anti-inflammatory drugs, or suffers from acute diseases, or is in the acute attack period of chronic diseases, it is contraindicated for some vaccines, such as New Crown vaccine, which may affect the better immunization effect of the vaccine and fail to achieve the purpose of disease prevention; 3. This will affect the doctor’s judgment and delay the timely treatment. In addition, if adverse reactions also occur after vaccination, the symptoms of the disease and the adverse reactions of the vaccine may add up to make the clinical manifestations of the patient more complicated and treatment may be more difficult.
