So, going skiing at Easter. Can’t double jab 12 year old due to 12 week wait (4 days short). However, France is happy with one jab so long as proof of covid in last 6 months. How do I get proof of covid? travel company is saying gp, gp saying 119, 119 has no idea but not them. Happy to pay gp as cheaper than testing every single day!!!! Please help!
