Rotavirus Vaccines Linked To Severe Intestinal Disorder In Infants

New study finds link between rotavirus vaccines and intussusception

  • New study looks at data from approximately 1.3 million rotavirus vaccines

  • Occurrence rate of intussusception is approximately 1 to 2 per every 65,000

A new study finds that rotavirus vaccines may cause development of a serious intestinal disorder called intussusception.  The study reviewed information from the administration of approximately 1.3 million doses of rotavirus vaccines.

Approximately 1.2 million doses of rotavirus vaccines were Rota Teq.  Over 100,000 of the rotavirus vaccines were Rotarix.  Rota Teq is the most commonly used rotavirus vaccine.

Researchers found that for every 1 million Rota Teq rotavirus vaccines given, an additional 15 cases of intussusception were identified.  This equates to one case of intussusception per every 65,000 rotavirus vaccines received.  The instances of infants vaccinated with Rotarix rotavirus vaccines were too few to include in the study.

RotaShield, an earlier version of the rotavirus vaccine, was taken off of the market for its rate of one to two cases of intussusception linked with each 10,000 people vaccinated.

During their clinical trials, both Rota Teq and Rotarix were not found as having links to occurrences of intussusception; however both of the rotavirus vaccines were continuously monitored by health officials.

Rotavirus is the most common cause of diarrhea among infants.  Reportedly nearly every child has been infected with rotavirus by age five.  “The virus is transmitted by the faecal-oral route. It infects and damages the cells that line the small intestine and causes gastroenteritis (which is often called “stomach flu” despite having no relation to influenza).”  Immunity reportedly develops as each infection occurs.

Intussusception is a medical condition in which one part of the intestine folds into another portion, this process is similar to the way that a collapsible telescope slides together.

Researcher Katherine Yih of Harvard Medical School states that parents should be aware of the chances of this occurrence when getting their child vaccinated, however she believes that the benefits still outweigh the risks.
