And according to the most optimistic predictions, the skies will only really begin to open, and travel and tourism will resume, sometime between 2023 and 2024. “We live in a global world, with or without realizing it,” said Michael Edelstein, a professor of population health in Bar-Ilan University’s Faculty of Medicine, in an interview with the Post. And it is also unlikely that countries with excess vaccines would start sharing vaccines until they have completed their own vaccination campaigns. People will look for places where they can enjoy “open-air tourism,” outdoor tourism and nature-based tourism. Airports will also require a shift for travel to resume, such as putting crowd control and social distancing measures in place.
