【明報專訊】The summer holidays are approaching. Had it not been for a COVID-19 situation, many people would have started making intense preparations for travel and vacations already. However, in this summer, getting vaccinated is the only choice for those who want to travel. Given the progress in vaccination in Europe and the US, the governments of many countries intend to reopen their borders in the summer. Yesterday (June 1), the European Union's (EU) COVID-19 vaccine passport scheme, which is aimed at preparing for the restart of the tourist industry next month, came into effect. It is believed that the scheme, initially limited to people in the region, will be extended to people in other regions soon if its implementation is satisfactory.
