Sanofi flu vaccine batches rejected after Taiwanese inspectors find impurities: report

After a manufacturing hiccup led Chinese regulators to temporarily hold off on imports of Sanofi's pediatric vaccine Pentaxim earlier this year, authorities in Taiwan have now returned two batches of flu vaccines made by the global giant. Taiwan imported the flu vaccine batches—which contained more than half a million doses—in October. During an inspection, Taiwan FDA employees found that some doses contained black and white suspended matter, rather than being translucent and colorless.
