Do not contact your us (your GP surgery) about your COVID-19 vaccination status. GPs cannot provide letters showing your COVID-19 vaccination status.
Please see this latest advice from the government:
https://www.gov.uk/guidance/demonstrating-your-covid-19-vaccination-status-when-travelling-abroad
From 17 May, you may be able to show your COVID-19 vaccination status as proof of your status when travelling abroad.
There are not many countries that currently accept proof of vaccination. So for the time being most people will still need to follow other rules when travelling abroad – like getting a negative pre-departure test.
How to access your COVID-19 vaccination status
You can access your COVID-19 vaccination status through the free NHS App from 17 May. You can access the app through mobile devices such as a smartphone or by tablet. Proof of your COVID-19 vaccination status will be shown within the NHS App. We recommend that you register with the app before booking international travel.
