Health and care professionals provide care as a local team. This means that the right people can work together to ensure your care is planned and co-ordinated. They work within strict rules and focus on getting the best outcomes for their patients. They are ethically accountable to their professional bodies for their actions, including on what is appropriate to share and when. Sharing is subject to strict written agreements and/or contracts on how it will be used with tight controls to maintain confidentiality and security.
Regarding certificates or evidence about your COVID vaccination status GPs cannot issue a certificate to demonstrate your vaccination status. Please see https://www.gov.uk/guidance/demonstrating-your-covid-19-vaccination-status-when-travelling-abroad for further information. Proof of your vaccination status will be available in the NHS app from 17th May 2021, and in some of the other apps that provide you with Patient online services.
