Official batch control of influenza vaccines: Is it still useful?

13 batches which did not meet the specifications of influenza vaccine were detected by the OMCL network between 2006 and 2016 which would not have been identified by the manufacturer. This demonstrates the impact of governmental batch release. Together with the intrinsic values of the OCABR system and keeping in mind that vaccines are given to healthy often young individuals, governmental batch release of influenza vaccines is still justified.
