According to CDC policy, Booster are considered immediately up-to-date (fully vaccinated), no two weeks waiting period. However, I am getting the following error message from FlyReady: Destination: AMS

Error: Not enough time has passed from your final vaccination. Please double check that your vaccine was taken in a timeframe which qualifies for fully vaccinated and try again.
The only reason I got the booster shot yesterday is to pass FlyReady. I am worried about my flight tomorrow. Can anyone help? Detailed facts down below:Vaccination info:
