Rotavirus vaccine impact

Posted:

Since the introduction of the Rotavirus vaccine, cases of the illness have dropped significantly, according to a new CDC report.

Before the vaccine, Rotavirus was responsible for 20 to 60 deaths, and hundreds of thousands of emergency room visits in the U.S. every year.

Vaccination started in 2006. One year later cases dropped 64 percent.

From 2008 to 2009 cases went up slightly, but overall were still much lower than before the vaccine was recommended.

Experts say they think babies who weren't vaccinated are also seeing some protection, as the drop in cases outnumbers the children who got the vaccine.

Rotavirus is marked by severe diarrhea in children less than five years old, and usually strikes in the winter and spring months.

The study also found the rotavirus season was shorter after the vaccine was introduced.  It was led by researchers at the CDC and published in the MMWR.
