LITTLE ROCK, AR - The state's top health official says some central Arkansas residents think they're protected from the flu, when they're not.
State Health Department Director Dr. Fay Boozman says about 300 people who got flu shots on November 3 at the State Fairgrounds in Little Rock got ineffective vaccine.
The Health Department sent a letter Tuesday to all of the approximately 2,300 people inoculated that day. The letter says some doses of vaccine were accidentally frozen and made ineffective, and those who got those shots will need to be inoculated again.
According to the health agency, those who got their shots between 10 a.m. and 8 p.m. that day need to get new shots.
Officials said someone working at the Fairgrounds clinic that day mistakenly turned down the temperature of a portable cooler, and vials of vaccine it held were frozen.
