Redhelen72 - how do you come to that conclusion? Your link clearly states, under 'Proof of vaccination status':
"For travellers aged 18 and over, France will recognise you as ‘vaccinated’ for entry purposes if you completed your initial vaccine course within the last 9 months. If more than 9 months have elapsed since your initial course, and you have not since received a booster, you will be considered unvaccinated and must follow the rules detailed below."
and under 'If you’re not fully vaccinated':
"From 31 March 2022, travellers from the UK aged 12 years and over who are not fully vaccinated need to provide:
A negative PCR test result taken within 72 hours or an antigen test result taken within 48 hours pre-departure."
