Abstract

A vaccine clinical trial is a research study in humans which aims to investigate or confirm the clinical, pharmacological, or immunological effects of a vaccine to establish the vaccine’s safety and/or efficacy. Once a promising vaccine candidate has been chosen from preclinical studies, it goes through a number of phases of clinical trials in humans before and after licensure.
