Recalled H1N1 vaccine distributed in Alameda Co.


The health department announced Wednesday it had distributed 1,900 doses of the vaccine, a nasal spray commonly known as "flu mist," to six private providers and community based clinics.

The vaccine was recalled Tuesday, but it was not due to safety concerns, according to the Centers for Disease Control and Prevention.

The manufacturer, MedImmune, had notified the agency that 13 batches of the spray have a shorter shelf life than previously specified.

This means the vaccines lose their potency sooner than they are supposed to, but they were sufficiently strong when they were distributed, according to the CDC.

The vaccines weren't expected to fall below normal potency levels until next week, and people who already had the vaccine don't need to get another one.
