When the medical research team wants to develop a vaccine, medication, treatment, and medical devices. Clinical trials are the only mechanism in the medical science to check the efficacy of the drug or treatment and to know about the safety of the drugs because if the trials are not approved by the FDA then not any drug, treatment will not use in the world and it is mostly considered unsafe. There are four phases that every drug, treatment, and vaccine has to pass through them. Participants in the clinical Trails are an integral part of the clinical trials without participants, not no research could be conducted.
