The corruption prosecutor's office submitted to parliament on Friday a file on the supply of influenza vaccines in the period 2009-2010, as the investigation has come across the name of politicians, sources said. 
The health minister during the period in question was the current European Commissioner for Migration Dimitris Avramopoulos. 
The file had initially been closed but it was reopened after an investigation was ordered into the Novartis case of alleged bribery.
