The United States sent nearly 900,000 doses of the Pfizer coronavirus vaccine to Mongolia.

The 899,730 doses, sent through COVAX, the global vaccine-sharing initiative co-led by Gavi (the Vaccine Alliance), the WHO (World Health Organization) and CEPI (Coalition for Epidemic Preparedness Innovations), are in addition to 188,370 doses of the Pfizer vaccine shipped to Mongolia in September. The U.S. has also provided more than $4 million to support the country’s pandemic response.

A low-income country bordered by vaccine-producing neighbors, China and Russia, Mongolia has been able to secure millions of vaccine doses largely through deals with Moscow and Beijing. It has administered at least 4,383,409 doses of COVID vaccines so far, according to its Ministry of Health. That’s enough for about 68% of the country’s population, assuming each person receives two doses.
