The FDA has notified physicians and patients that some cases of intussusception, a form of intestinal obstruction, have been reported after receiving the new rotavirus vaccine. This has been and is being watched very closely since the previous rotavirus vaccine was recalled eight years ago due to a possible association between intussusception and that vaccine. In extensive research prior to its release, there was no association between this rotavirus vaccine and intussusception.
This is not a cause for alarm at this point because the number of cases is not any higher than one would expect in the general population; in other words, there is not a higher rate, nor is there anything to suggest that the vaccine is responsible for these cases. The FDA is just trying to be sure all cases are being reported due to the issues with the previous vaccine.
