Is there a test proof for flying to a different country?
If I understand your question correctly, I believe you are asking if proof of the Covid vaccination can be used to fly overseas.
The government are still in discussions about what evidence may be required for travel and leisure. In the meantime so I do not have a complete answer to your question at this time. I definitely recommend downloading the free NHS app that will hold any vaccine details within your medical record.
