The FA are also hopeful that Monday's welcome development will mean England can remain a key venue for the European Championship next summer.
Premier League chief executive Richard Masters is likely to press for fans to return after lockdown when he appears at a Department for Digital, Culture, Media and Sport select committee on Tuesday — and the promise of a successful vaccine will certainly boost those calls.
