My favorite part was this:
"The FDA learned about the contamination after an academic research team using a novel technique to look for viruses in a range of vaccines found the material in GlaxoSmithKline's product and told the company, Hamburg said. The drug maker confirmed its presence in both the cell bank and the seed from which the vaccine is derived, suggesting its presence from the early stages of vaccine development, she said. The FDA then confirmed the drug maker's findings."
I was shocked when I first read that the FDA actually has been investigating vaccines, then I understood it wasn't actually that. Right.
