A vulnerable population is referred to as “imply the disadvantaged sub-segment of the community requiring utmost care, specific ancillary considerations and augmented protections in research. The vulnerable individuals’ freedom and capability to protect one-self from intended or inherent risks is variably abbreviated, from decreased freewill to inability to make informed choices” (Shivayogi, 2013). Many are considered as vulnerable populations like elderly, children, religious, racial, or ethnic minorities, pregnant women, terminally ill, and physically and intellectually challenged people (Shivayogi, 2013).
