Sanofi Pasteur recalls doses of pediatric H1N1 vaccine


NEW YORK Sanofi Pasteur has recalled nearly 1 million doses of an H1N1 vaccine for children because they aren’t strong enough, according to the Centers for Disease Control and Prevention.

Sanofi Pasteur notified the CDC and Food and Drug Administration on Dec. 7 that during a routine test, it found a batch of the vaccine, for children ages 6 months to three years, to have a low potency. The recall affects five lots with a total of 800,000 0.25 milliliter doses of the vaccine.

The CDC said it did not have any concerns about the safety of the vaccine and still expects the recalled doses to be effective, so children who received them do not need to be revaccinated. The recall does not affect the adult formulation of the vaccine.
