The Food and Drug Administration is planning to release on Tuesday an outline of its conditions for approving COVID-19 vaccines, The Wall Street Journal reported. The FDA said no vaccine will be approved unless it clearly demonstrated proof of safety and effectiveness through a clinical study, and will have to be at least 50% more effective than placebo, the WSJ reported. Vaccine makers will be required to keep monitoring safety after approval and recommend that people who received the vaccine be followed for a year after treatment, the report said. The FDA assured that it will not reduce standards or cut corners in its review to approve a vaccine, the report said.
