It’s flu shot time. The Centers for Disease Control and Prevention says it's time for people to start getting immunized. Last year less than half the U.S. population got immunized. More children than ever got shots last year and officials are hoping for more success this year. Flu shots are recommended for nearly everyone ages 6 months and older. The latest vaccines are capable of protecting against 4-6 strains of flu. If you can’t stand shots a nasal spray is also available. It’s also necessary to get a shot every year . The immunity “wears off” over a period of time. Local health departments, clinics, and pharmacies all offer immunizations.
