The research conducted by Ward (2014) evaluated the total impacts and influences of externalities in respect to the vaccination of influenza as it developed its spread to the patients targeted. Ward employed a triple-difference design while assessing a vaccination program in Ontario and the improvements perceived from it for several years. The research study brought the essence of providing the higher vaccination as an attribute facilitating the improvement of health status. It was noted that the expansion of the vaccination effects was beneficial to the regions. The benefits included lowering of an initial standard of disease prevalence where the older adults accrue many advantages. In perspective, this essay criticizes the research and presentation made by Ward through assessing various aspect of his presentation. The researcher introduces by laying out the basic purpose of performing his study. The evaluation of this introduction dictates that there are various reasons why the research is essential. For instance, it has been stated that assessing the broad-based program is the sole purpose of identifying the underlying benefits. In fact, the assessment proceeds to develop a strategic reasoning criterion that seasonal epidemics demand prevention which in turn prevents cure. It does not only develop arguments about the policies applied in the approval and dissemination of the vaccines, but also provides an intricate analysis of prevailing health effects of the disease. The introductory section argues that children are threatened significantly by the disease if appropriate and reliable vaccines do not work properly (Fiore, 2012). In this section, the information has been presented from such reputable and peer reviewed sources as the World Health Organization. The researcher identifies the risky situation in cases where early-life infections lead to disabilities. In consideration of accuracy and generalization of the study, Ward makes his research analysis reliant on the quality of the subject vaccines. Furthermore, the supervision of survey data is constructed in a platform where hospital admissions and failure to attend employment duties are evaluated for a period of eleven years. Although the research does not indicate the particulate data set, collection methods and their reliabilities, it is apparent that some results portray fundamental insight for future studies. The research results inform that there was a 48% decrease in the admission of pneumonia patient, 14% reduction in absenteeism, and decrease in death tolls related to the disease by 0.009%. However, it is not apparent that the randomization of the research can facilitate generalization of the results. Essentially, handling the research from the UIIC region may exhibit some unique characteristics not found within other regions across the globe. The background information presents a case that demands professional attention. The researcher argues that the prevailing issues where the prevalence and effects of the influenza virus has been availed on a worldwide base. It evaluates the current efficacy of the vaccine, its developments, and other improvements noted on the virus. This section points out such let
