This medicine is given by your healthcare provider. The vaccine is usually given between the ages of 12 and 15 months, and a second dose at age 4 to 6 years. It may be given earlier, if at least 3 months after the first dose. It can be given to older children if they have not had the vaccine or the disease yet. Adults and children age 13 or older should get 2 doses at least 4 weeks apart. Adults who have previously received only 1 dose should get a second dose.
Your healthcare provider will tell you how many shots you will need and when you should get them. Get all the shots on schedule to provide complete protection. Keep a record of when each vaccine was last given. If a shot is missed, contact your healthcare provider right away and schedule another appointment for the shot.

Your healthcare provider may recommend acetaminophen (Tylenol) to help lower a fever or to relieve any pain or discomfort.
This medicine may cause pain, tenderness, irritation, rash, or swelling on the skin where injections were given. The pain or tenderness should go away in a day or two.
