FDA says COVID-19 vaccine must be at least 50% effective to be approved.
The Washington Post (6/30, McGinley) reports the US Food and Drug Administration on Tuesday said that to be approved, a COVID-19 vaccine must “prevent disease, or decrease its severity, in at least 50 percent of the people who receive it.” Still, “many people believe a vaccine initially would be made available through a much lower standard for temporary approvals.”
The Wall Street Journal (6/30, Burton, Subscription Publication) reports that the FDA said it would not approve a vaccine based on it resulting in antibodies in a patient’s bloodstream.
