These regulatory actions are precautionary, since so far there is no indication that this suspected quality defect has any impact on the safety or efficacy of the vaccines in question.
The European Medicines Agency has no formal legal role in this case, as the products are nationally authorised, but is taking a supporting role by bringing expertise from the network together to assist AIFA and the authorities in the other Member States.
AIFA is taking the lead on behalf of the EU in investigating the suspected quality defect in order to determine whether it affects the safety and efficacy of these vaccines, and whether the affected batches should be permanently removed from the market. The suspected defect involves the aggregation of proteins that are a normal part of the vaccines.
All Member States will evaluate the impact of the potential unavailability of the batches in question on their seasonal influenza vaccination programmes, which are an important public-health activity at this time of year.
The Agency and the Member States continue to monitor the situation.
