The medical certificate, which should be no older than 76 hours, is among a number of proposed protocols now on the table for implementation.

Unless there is a vaccination for COVID-19, having any medical certificates 76 hours or shorter would be no indication as you could get it on the way to the airport and be asymptomatic and undetectable upon arrival.

Until there is a vaccination for COVID-19, all guarantees are off the table.
