The National Vaccine Information Center (NVIC) called for Merck to voluntarily recall its live rotavirus vaccine – RotaTeq – which is contaminated with parts of a lethal virus that infects pigs – porcine circovirus 2 (PCV2) – and publicly pledge to clean-up the vaccine.
On May 7th, GlaxoSmithKline (GSK) publicly pledged to re-formulate its rotavirus vaccine, Rotarix, by removing DNA from a non-lethal pig virus (PCV1). RotaTeq is contaminated with DNA from both PCV1 and PCV2. PCV2 is an aggressive virus that causes immune suppression, wasting disease and death in baby pigs.
