Infant :: Merck’s RotaTeq rotavirus vaccine may harm infants

The US FDA has issued a Public Health Advisory notifying health care providers and consumers about reports of intussusception following rotavirus, live, oral, pentavalent vaccine (RotaTeq) administration.

The Food and Drug Administration (FDA) is notifying health care providers and consumers about 28 post-marketing reports of intussusception following administration of Rotavirus, Live, Oral, Pentavalent vaccine (trade name RotaTeq), manufactured by Merck and Co., Inc.

Intussusception is a serious and potentially life-thr eatening condition that occurs when the intestine gets blocked or twisted. One portion of the intestine telescopes into a nearby portion, causing the intestinal obstruction. The most common site is where the small intestine joins the large intestine.

Intussusception can occur spontaneously in the absence of vaccination. Of the reported 28 cases of intussusception, the number that may have been caused by the vaccine, or occurred by coincidence, is unknown.

FDA is issuing this notification both to encourage the reporting of any additional cases of intussusception that may have occurred or occur in the future after administration of RotaTeq, and to remind people that intussusception is a potential complication of RotaTeq,.

FDA and the CDC will continue close monitoring of intussusception and other adverse events associated with RotaTeq.
