RICHMOND, VA (WWBT) - H1N1 manufacturer Sanofi Pasteur announced Tuesday the recall of 800,000 vaccines intended for young children ages six months to three years.
It was a voluntary recall and there is no safety issue for people who received the vaccines.
The problem is with the potency of the shots.
The Virginia Department of Health said Virginia received 23,700 of the recalled doses.
Health officials recommend children those ages get two doses, spaced about a month apart.
It's believed that most of the doses have already been given, but health officials say they don't think children need to be re-vaccinated.
The shots passed potency tests when they were first shipped, but tests indicate the potency dipped after that.
