Just a refresher: if travelling from the above countries, visitors will not be made to quarantine, provided that they are in possession of a valid and recognised vaccine certificate.
As it stands, the authorities recognise vaccine certificates of Malta, the EU, the UK, the UAE, the US, Serbia, Turkey, Gibraltar, Jersey and Guernsey, Qatar, Albania, Australia, Egypt, Lebanon and Canada. Certificates are only recognised as valid if holders have been given two shots of vaccines manufactured by Pfizer, Moderna or AstraZeneca, or the single shot of the Janssen vaccine, manufactured by Johnson & Johnson.
