There seems to be some confusion about the validity of the EU issued Vaccination Certificate when travelling to the UK, currently (21st July) although health authorities from both UK and EU sides have recognised the same vaccines, the UK do not recognise the EU COVID certificate, quarantine and testing exemptions are only valid in the UK if the vaccinations are administered in the UK, meaning that travellers entering the UK with an EU Certificate will still be subject to quarantine and testing restrictions, for anyone travelling to the UK with an EU Certificate it is advisable to check the current situation.
