Vaccinating children against rotavirus may indirectly protect adults too, study finds

24.01.2013
Pediatric rotavirus vaccination also indirectly protects unvaccinated adults from the highly contagious cause of severe diarrhea and vomiting, suggests a new study published in Clinical Infectious Diseases and available online. The findings suggest pediatric immunization against the virus may be more cost effective than previously thought, given rotavirus-related health care costs among adults.

Before the vaccine, rotavirus caused an estimated 24 million outpatient visits, 2.4 million hospitalizations, and 453,000 deaths in infants and young children worldwide each year. Following the introduction of the pediatric rotavirus vaccine in the United States, declines in the disease have been seen in both vaccinated and unvaccinated children.

Evan J. Anderson, MD, now at Emory University, and a team of researchers at Northwestern Memorial and Children's Memorial Hospitals in Chicago looked into whether the vaccine's benefits extended to unvaccinated adults. They compared the prevalence and genotypes of rotavirus in stool samples collected from approximately 3,500 adults before widespread implementation of pediatric rotavirus vaccination (2006-2007) with the prevalence in samples collected from 2008 to 2010. The researchers found the number of unvaccinated adults who had rotavirus was almost halved in the years after the vaccine was introduced for use in children in the U.S.

"In adults with diarrhea who see the doctor and who have testing for bacterial infections, we noticed an almost 50 percent decrease in rotavirus," said Dr. Anderson. With previous research estimating $152 million in total adult inpatient hospital charges related to rotavirus each year in the U.S., this latest data may make pediatric vaccination "much more cost effective than previously believed."

Dramatic declines in rotavirus prevalence were evident in both adults admitted to the hospital and in those treated as outpatients. The findings suggest that "vaccinating children can protect adults from rotavirus by decreasing the amount of rotavirus circulating in the community," Dr. Anderson said. Because rotavirus genotypes change from year to year, the researchers also noted that "ongoing surveillance is needed to determine whether this impact is sustained."

The positive effect of pediatric rotavirus vaccination programs on the prevalence of disease among both young and old, vaccinated or not, underscores the need to support and encourage vaccination, Dr. Anderson said. "By improving the health of children, we indirectly improve the health of adults."

The study is available online. It is embargoed until 12:01 a.m. EST on Thursday, Jan. 24, 2013:

Clinical Infectious Diseases is a leading journal in the field of infectious disease with a broad international readership. The journal publishes articles on a variety of subjects of interest to practitioners and researchers. Topics range from clinical descriptions of infections, public health, microbiology, and immunology to the prevention of infection, the evaluation of current and novel treatments, and the promotion of optimal practices for diagnosis and treatment. The journal publishes original research, editorial commentaries, review articles, and practice guidelines and is among the most highly cited journals in the field of infectious diseases. Clinical Infectious Diseases is an official publication of the Infectious Diseases Society of America (IDSA). Based in Arlington, Va., IDSA is a professional society representing nearly 10,000 physicians and scientists who specialize in infectious diseases.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
