Taiwan is in talks with international bodies about Covid-19 vaccine passports, the head of its Centres for Disease Control said, which could help ease long-standing travel restrictions.

Taiwan has previously considered such a scheme, but has been extremely cautious about opening its largely-closed borders lest it lets in more infections, and is currently on high alert to stop the highly contagious Delta variant, Reuters reports.

Taiwan Centres for Disease Control Director-General Chou Jih-haw told reporters they have already begun talks with other governments and international organisations about vaccine passports.

“We hope we can quickly get into step with the international community,” he said, without giving details.
