Non-Safety Related Vaccine Recall

[indigo girl]

Although some headlines are screaming `5 million doses of flu vaccine being recalled', the reality is a bit less dramatic than these banners might suggest.

Maryland based MedImmune, makers of FluMist, has voluntarily recalled the remaining doses from 13 lots of vaccine sent out in October and November. While the original lots consisted of 4.7 million doses . . . the `vast majority' of those have already been dispensed.

Once again, the concern is a reduction in potency over time, not over any safety concerns.

Vaccine manufacturers retain a small portion of each lot of vaccine produced and perform ongoing potency tests. In this case, the potency of the FluMist dropped over time.
