The US Centers for Disease Control and Prevention (CDC) yesterday notified healthcare providers that 50 lots of Sanofi Pasteur’s pandemic H1N1 vaccine in prefilled syringes have a shorter shelf life than shown on the label. The CDC said in its Health Alert Network message that Sanofi’s routine stability testing of vaccine that had already been shipped to providers showed that although the lots remained potent, they are losing potency more rapidly than expected. The company said the prefilled syringe doses in the affected lots should be used by Feb 15, 2010, regardless of the expiration date shown on the package. The new expiration date does not apply to multidose vials.
