Instead, the vaccine causes the body to protect itself against the virus by building up antibodies. These antibodies are ready for action in about two weeks and are most effective for about two months after vaccination. It is recommended for seniors ages 65 and older, people with chronic illnesses such as asthma, diabetes and heart disease, and people in certain jobs such as health care workers and police officers. You cannot get influenza from the vaccine. The vaccine is very safe and effective.
Some people get a mild reaction such as a red or tender area where the vaccination was given.
The best time to get the flu shot is between early October and mid-November each year. Call your doctor or clinic for more information.
