The stance on vaccination was agreed upon during a meeting of the FIA World Motor Sport Council in December, with an F1 spokesperson confirming: "F1 [FOM] will require all travelling personnel to be fully vaxxed and will not request exemptions."
GPFans understands that 'fully vaccinated' includes the booster jab which is a requirement for entry to multiple countries.
The stance extends to all personnel working within the paddock and includes guests of the teams.
It could prove problematic for medical car driver Alan van der Merwe who missed races in Qatar, Saudi Arabia and Abu Dhabi due to his vaccination status last year.
In making this decision ahead of the season, F1 will hope to avoid scenes similar to those of the Australian Open tennis tournament where Novak Djokovic was detained then deported.
It is possible blanket vaccination will see the sport ease back on its testing regime and relax the social bubbles of recent years to bring a level of normality back to paddock life.
