“…In Australia, where the VZV vaccine was publicly funded in November 2005 (43), the amplitude of information seeking was severely dampened by the end of 2007. In the United States, immunization began in 1995 (31), and Canada required the vaccination starting in 2000 (44). In these two countries, where the VZV vaccine introduction predated Google Trends data, little seasonality was observed in the Google Trends data (Fig.…”

Public health surveillance systems are important for tracking disease dynamics. In recent years, social and real-time digital data sources have provided new means of studying disease transmission. Such affordable and accessible data have the potential to offer new insights into disease epidemiology at national and international scales. We used the extensive information repository Google Trends to examine the digital epidemiology of a common childhood disease, chicken pox, caused by varicella zoster virus (VZV), over an 11-y period. We (i) report robust seasonal information-seeking behavior for chicken pox using Google data from 36 countries, (ii) validate Google data using clinical chicken pox cases, (iii) demonstrate that Google data can be used to identify recurrent seasonal outbreaks and forecast their magnitude and seasonal timing, and (iv) reveal that VZV immunization significantly dampened seasonal cycles in informationseeking behavior. Our findings provide strong evidence that VZV transmission is seasonal and that seasonal peaks show remarkable latitudinal variation. We attribute the dampened seasonal cycles in chicken pox information-seeking behavior to VZV vaccine-induced reduction of seasonal transmission. These data and the methodological approaches provide a way to track the global burden of childhood disease and illustrate population-level effects of immunization. The global latitudinal patterns in outbreak seasonality could direct future studies of environmental and physiological drivers of disease transmission.

Context Population-level coverage for immunization against many vaccine-preventable diseases remains below optimal rates in the U.S. The Community Preventive Services Task Force recently recommended several interventions to increase vaccination coverage based on systematic reviews of the evaluation literature. The present study provides the economic results from those reviews. Evidence acquisition A systematic review was conducted (search period, January 1980 through February 2012) to identify economic evaluations of 12 interventions recommended by the Task Force. Evidence was drawn from included studies; estimates were constructed for the population reach of each strategy, cost of implementation, and cost per additional vaccinated person because of the intervention. Analyses were conducted in 2014. Evidence synthesis Reminder systems, whether for clients or providers, were among the lowest-cost strategies to implement and the most cost effective in terms of additional people vaccinated. Strategies involving home visits and combination strategies in community settings were both costly and less cost effective. Strategies based in settings such as schools and managed care organizations that reached the target population achieved additional vaccinations in the middle range of cost effectiveness. Conclusions The interventions recommended by the Task Force differed in reach, cost, and cost effectiveness. This systematic review presents the economic information for 12 effective strategies to increase vaccination coverage that can guide implementers in their choice of interventions to fit their local needs, available resources, and budget.

“…''Vaccination clinics in schools and day care centers can help reduce the number of susceptible children and shorten outbreaks when they occur'' (Hall, Galil, Watson, & Seward, 2000, p. 3). In a Canadian universal varicella school-based vaccination program, public health nurses implemented the clinics in 51 schools (Sweet, Gallant, Morris, & Halperin, 2003). This history of vaccination programs in the school setting paves the way for influenza vaccination in schools.…”

School-located vaccination has a long history in the United States. The 2008 Advisory Committee on Immunization Practices (ACIP) recommendation for annual influenza vaccination of all children 6 months through 18 years of age adds approximately 30 million individuals to the overall cohort recommended to have a yearly vaccination. The ability to administer this vast number of vaccinations may be beyond the capacity of primary care providers, leaving schools as an attractive venue for mass immunization clinics.
