Rotarix is a rotavirus vaccine that was approved by the FDA in April 2008. Along with RotaTeq, the other rotavirus vaccine, it helps protect children against mild and severe gastroenteritis that is caused by certain strains of rotavirus.
Warnings by the FDA to stop using Rotarix a few months ago got a lot of attention when it was found to contain DNA from porcine circovirus 1 (PCV1), even though this virus 'is not known to cause illness in humans or other animals.'
Although this same virus and a related porcine circovirus type 2 (PCV2) was also recently found in RotaTeq, the other rotavirus vaccine, the FDA, including its Vaccines and Related Biological Products Advisory Committee (VRBPAC) and other scientific and other public health experts, says that it is safe to use both rotavirus vaccines.
Not surprisingly, the news of resuming the use of Rotarix is not getting as much attention as the FDA warning to temporarily stop using it did.
