Turn to mass media if you need some motivation to get vaccinated. Mass media exposure can motivate people to get vaccinated which is especially true during disease outbreaks, shows new study by research teams at Ben-Gurion University of the Negev (BGU) and Soroka University Medical Center.

After an isolated wild type 1 poliovirus was discovered in a routine sewage sample in the Southern region of Israel in April 2013, the Israel Ministry of Health initiated an extensive risk communication campaign that led to constant coverage of the outbreak in local and national newspapers, television and radio reports, news websites, and on social media.

According to a new study in the journal Vaccine, researchers monitored daily immunization rate reports during the detected outbreak and discovered a significant increase in both bivalent oral poliovirus vaccines (bOPV) and other vaccinations during the period there was constant media exposure.

During the three-month time period studied, August to October 2013, 138,799 oral polio vaccines were administered to children under 10 years-old in Israel. Three to five days after major news coverage, vaccinations increased 79 percent in the Jewish population and 71 percent among high socio-economic subgroups.

Constant media exposure also prompted up to a 35 percent increase in other more routine vaccinations within these subgroups, such as diphtheria-tetanus-pertussis-hemophilus influenza and rotavirus. Researchers also noted positive media sentiments led to an increase in polio vaccines while reports of negative sentiments had no noticeable effect.

"This is further evidence that media coverage can impact public response during a health crisis," says Dr. Iftach Sagy, a researcher at the Soroka Clinical Research Center and a lecturer at the BGU Faculty of Health Sciences.

"It is important to release information quickly and be as transparent as possible to help contain public outbreaks and epidemics. If media outlets don't have sufficient information about risks, they focus on more sensational stories instead, which could have a negative impact."

For example, during the 2009-2010 H1N1 swine flu outbreak in Europe, when media attention declined after the epidemic reached its peak, vaccinations decreased which resulted in more deaths during the second wave, even though there were still sufficient quantities of vaccine available. Fortunately, the Israel Ministry of Health responded quickly and was able to successfully administer supplemental vaccinations during the silent polio outbreak without incurring any clinical infection cases.

"Infectious disease outbreak communications need to take into account the needs of different subgroups, build an equal partnership between government agents and the public, and engage in two-way communication to maintain trust," says Dr. Sagy. "It is important to have all of these elements in place to contain the spread of potential epidemics."

The team's findings suggest that governmental agencies should develop communication strategies tailored to different ethnic and socio-economic communities to address inherent risks and properly engage groups that are often mistrustful of media.
