Rome, November 9 - Italy's national pharmaceutical oversight body AIFA removed a precautionary ban on the Novartis V&D flu vaccines following an analysis of the shots. The health ministry and AIFA had blocked 500,000 vials of injectable vaccines from the US-based pharmaceuticals company as a precautionary measure pending the outcome of investigations into possible unwanted side-effects. "The tests showed no traces of quality defects," said an AIFA statement. The block came after Dutch pharmaceuticals company Crucell halted delivery of 2.3 million doses of its flu vaccine in Italy over unexpected test results. The health ministry has assured consumers there will be no shortages of vaccine as the flu season approaches.
