Monte Carlo travel

Hello guys,

Anyone who is travelling or has traveled recently to Monte Carlo recently I need some information about entry requirements in France and Monte Carlo please.

Planning to travel to play the EPT events there but I don't really understand how the whole covid-vaccination status works there. I had the Johnson first dose which makes me fully vaccinated but didn't have a booster shot. Do I need to have a PCR to go there? Travelling from England. will have to land in France by plane and then by car to Monte Carlo/Monaco.
