1 flu vaccine/year: After age 8, one flu vaccine per year is recommended. The vaccine can take up to two weeks to produce immunity in the body. However, influenza is generally more severe than a head cold, with fever, body aches, and respiratory symptoms. Take care of yourself with nasal saline, mist, fluids. If you develop more severe or prolonged symptoms, please see a doctor.
