For patients of 70 years and older, how effective is the use of the influenza vaccine at preventing flu as compared to patients who have not received the vaccine?
Foremost amongst the diseases preventable by vaccination is influenza. Worldwide, influenza virus infection is associated with serious adverse events leading to hospitalization, debilitating complications, and death in elderly individuals. Immunization is considered to be the cornerstone for preventing these adverse health outcomes, and vaccination programs are timed to optimize protection during the annual influenza season (Lang, 2012).

Provide a clearer understanding. Clear documentation can be provided regarding the content and application of the survey instruments so that other researchers can assess the validity of the findings. Standardized approaches permit the study to be replicated in different areas or over time with the production of comparable findings. It is possible to control for the effects of extraneous variables that might result in misleading interpretations of causality (although this can be challenging in the natural settings of …show more content…

The administration of a structured questionnaire creates an unnatural situation that may alienate respondents. Studies are expensive and time-consuming, and even the preliminary results are usually not available for a long period of time. Research methods are inflexible because the instruments cannot be modified once the study begins. Reduction of data to numbers results in lost information. The correlations produced (e.g., between costs and benefits, gender, and access to services or benefits) may mask or ignore underlying causes or realities.
The rational for choosing this study is that quantitative research methods and measures are usually universal, like formulas for finding mean, median and mode for a set of data. The concepts in quantitative research methods are usually expressed in the forms of variables.
