Recall of H1N1 vaccines

As many of you are probably aware, the CDC and Sanofi announced a recall of 800,000 doses of H1N1 vaccine yesterday. This was a non-safety related recall of 4 lots of the vaccine that were manufactured as pre-filled syringes intended for ages 6-36 months. As it turns out, testing done by the manufacturer after release showed lower potency levels than necessary to induce an immune response. Our patients will be happy to learn that TLC received no vaccines from the four lots that were recalled, so no further concern is necessary at this point in time.
