During the 1996-1997 influenza season, all the lots of influenza vaccine manufactured by Parke-Davis were recalled. This voluntary recall by the manufacturer was prompted by the finding of decreasing potency of the A/Nanchang/933/95 (H3N2) component of the vaccine. The primary cause of this lowered potency has been identified as primarily due to the presence of sodium bisulfite which was used to neutralize residual formaldehyde which in tutor is used to inactivate the live influenza vaccine strains. This paper reviews these events and what we have learned.
