The immunity takes effect quickly, but lasts only 1 to 3 months. Your doctor will explain. Certain types of this medicine are also used for other conditions such as B-cell chronic lymphocytic leukemia and HIV infections in children, and after bone marrow transplants. These injections are given by your doctor or nurse. Some are given in the hospital.
Some immunizations require more than one injection over a period of time.
Be sure to have the recommended number of shots on schedule. Be sure to tell the doctor if you have ever had a reaction to an immunization in the past. You may feel tenderness, pain, or muscle stiffness where you had the shot. This may last for several hours. Tell your doctor if you have any side effects that continue or get worse.
