He stated that the FDA had found "no red flags" regarding pregnant women

A "Red Flag" (or Safety Signal) is an actual, observed increase in adverse events in real-world data.

What he was discussing in the text was a theoretical risk.

A "Theoretical Risk" is a hypothetical concern based on known biological mechanisms (e.g., "high fevers can cause miscarriages, so a vaccine-induced fever might do the same").
