The Centers for Disease Control and Prevention (CDC) has announced a non-safety related voluntary recall of certain lots of H1N1 influenza intranasal vaccine.

The vaccine, manufactured by MedImmune, successfully passed pre-release testing for purity, potency and safety. However, because its potency is now or might soon be below the specified lower limit, MedImmune will send providers directions for returning any unused vaccine from these lots.

According to the Iowa Department of Public Health (IDPH), Iowa was allocated approximately 46,900 doses of the affected nasal mist vaccine.

“The majority of this vaccine was administered in October, when its potency was not an issue,” said IDPH Immunization and Tuberculosis Bureau Chief Don Callaghan. “Because the vaccine was administered long before this recall, there are no concerns about its effectiveness.” Individuals who received the affected intranasal vaccine do not need to be re-vaccinated.
