Sanofi Pasteur (Lyon, France) has recalled an additional six lots of its Influenza A (H1N1) 2009 Monovalent Vaccine in prefilled syringes after routine testing found that the antigen content had declined below the specification limit.
In December 2009, the company recalled 4 lots of its H1N1 pediatric vaccine in prefilled syringes after routine stability testing determined that those lots no longer met the potency specification.
As with the December recall, the FDA has stated that there are no safety concerns related to the recall and that individuals immunized with these lots do not need re-immunization.
