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.
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.
So from what you have provided, just your daughter needs a neg PCR with 72 hours or LFT 48 hours before travel.
Do you need to provide proof of where you are staying / travelling to ?
