Will the US FDA authorize a new vaccine targeting COVID-19 in 2023?

Many COVID vaccine possibilities are being explored, including nasal drops. Some have speculated that there may be a high bar for new vaccine approvals. The authors point out that (1) a new vaccine would likely need to prove it is more effective than the existing ones, even though the existing ones are many variants behind the type of Covid we have in 2023, and (2) the FDA is less likely to issue an Emergency Use Authorization (EUA) due to a perceived reduction in the state of emergency of COVID-19.
