Some studies show no increased risk of intussusception after rotavirus vaccination. Some studies do show a small increase in risk, but we don't know if the results from the U.S. studies are reliable. However, in all the studies which have shown an increased risk, whether it is reliable or not, have only shown an extremely slight overall increase. What we do know is that before vaccination, rotavirus infected 95% of children between 3 months and 3 years old, resulted in 200,000 ER visits annually, and killed 60 children ever year. However, because there is a possible risk, the vaccine injury compensation program (the VICP) has made intussusception a "table injury." That means, that if your child develops intussusception after a rotavirus infection, you may be eligible for compensation. There are time limits, however, so you should contact an attorney experienced with the VICP, as soon as possible.
