Intussusception and Oral Poliovirus Vaccination: Is There an Association? [PDF]

American Journal of Epidemiology, 2004
Oral rotavirus vaccine was voluntarily withdrawn from the market after studies observed an increased risk of intussusception within 2 weeks after immunization. Concern has been raised that other orally administered vaccines, such as oral poliovirus vaccine (OPV), may also be associated with intussusception.
