The United States Food and Drug Administration (FDA) on June 30 issued guidance for commercial vaccine manufacturers and other entities that are developing COVID-19 vaccine. The US FDA said it expects manufacturers to show that the vaccine is 50 percent effective in a placebo-controlled trial before it can be widely deployed for the treatment of the disease. The FDA issued the guidance to make clear to the manufacturers and sponsors what data would be required to meet regulatory standards for COVID-19 vaccine deployment.

"We recognize the urgent need to develop a safe and effective vaccine to prevent COVID-19 and continue to work collaboratively with industry, researchers, as well as federal, domestic, and international partners to accelerate these efforts. While the FDA is committed to expediting this work, we will not cut corners in our decisions and are making clear through this guidance what data should be submitted to meet our regulatory standards. This is particularly important, as we know that some people are skeptical of vaccine development efforts,” said FDA Commissioner Stephen M. Hahn, M.D.
