The U.S. Food and Drug Administration (FDA) is expected to grant emergency use authorization (EUA) for one or more COVID-19 vaccines before the end of the year — perhaps even before the end of the day, given today’s advisory committee meeting.
The agency’s decision on these EUAs will balance the need for additional data on safety and efficacy against the potential to protect at-risk groups as quickly as possible. EUAs tip the balance in favor of speed, which can be reasonable for these populations given the circumstances, especially in light of the strong trial data reported for three COVID-19 vaccines since mid-November. But the tradeoff is very real: vaccine EUAs will substantially lower the likelihood of ongoing trials completing and new trials successfully recruiting volunteers. There are a few ways to minimize these consequences.
