In the United States and many other wealthy countries, you can get a free COVID vaccine at supermarkets, pharmacies and clinics.

In other countries, it's a very different story. 

"The vaccine is not available in the North (of Yemen)," says Jasmin Lavoie with the Norwegian Refugee Council, who's based in the northern city of Sana'a. "If a person wanted to be vaccinated, that person would have to go to the south. So drive around 15 to 20 hours crossing front lines in the mountains." Even then, after such a treacherous journey through a war zone, it's not clear if doses would be available. Like many low-income countries, Yemen has struggled to get hold of vaccine.
