When COVID-19 first began spreading around the globe, the world responded by locking down. The rules were clear: Do not see people you do not live with. Do not gather together in groups. Wear masks. Do not touch strangers, or acquaintances, or even loved ones.And of course: Do not hug.It left many of us lonely and starved for connection.

Then, vaccinations began rolling out, albeit slowly. By July 6, according to The New York Times, more than 3.29 billion vaccine doses have been administered across the world. But some countries — particularly those in North America and Europe — are much more highly vaccinated than others, including countries with lower incomes. In some areas in the U.S. with the highest vaccination rates, another new normal began springing up. Public health experts announced that, if everyone is vaccinated, you can reunite with your family, friends, loved ones, and, yes, even acquaintances. Videos of these reunions flooded our feeds, and gave us something pure and nice to look at! Here are some of our favorite reunions and hugs as the world began to open up thanks to COVID-19 vaccinations.

While these joyous moments are just that — joyous — they should also be viewed with trepidation. In the U.S. and other nations with higher vaccination rates, this is possible. But in places like Africa and Oceana, where vaccinations aren't nearly as accessible, reunions aren't as festive. Vaccine hesitancy is on the rise in some communities even in the U.S., and the delta variant, which highly transmissible and dangerous, is becoming a dominant and powerful strain.
