As Bolivia struggled late last year to secure deals with large drug firms to supply COVID-19 vaccines, the incoming president, Luis Arce, turned to Russia for help.

By the end of December, Bolivia clinched its first major COVID-19 vaccine deal, with enough shots for some 20% of the population. The first Sputnik V doses arrived in the country in late January, just as virus cases were spiking.

¡°It was a really marathon task,¡± said Bolivian trade minister Benjamin Blanco of the procurement quest, but Russia¡¯s political will made it possible. Western vaccine makers ¡°told us developing countries that we had to wait until June.¡± He didn¡¯t name names.
