Emergency use authorization
Vaccines, medicines, diagnostic tests and medical devices require approval for their usage from a regulatory authority, which is the Central Drugs Standard Control Organisation in India. This approval is granted after assessing its safety and effectiveness. This is generally a prolonged process. The emergency use authorization (EUA) is a mechanism used by the regulatory bodies to grant interim approval in case of emergencies. This is done only when there is sufficient evidence. The final approval, however, is given after completion of trials.
