Argentina has approved Russia’s one-dose Sputnik Light as a standalone vaccine and a booster shot, the Russian Direct Investment Fund (RDIF) said yesterday citing Argentina’s Health Ministry.

Argentina was one of the first countries to widely use Russia’s Sputnik V COVID-19 vaccine, but delays in deliveries led the country in August to offer second doses of Moderna and AstraZeneca vaccines to citizens who received the first dose of Russia’s Sputnik V.

RDIF, which markets Sputnik V internationally, said a study in Argentina showed Sputnik Light was an “effective universal booster” when combined with vaccines produced by AstraZeneca, Moderna, China’s Sinopharm and CanSino Biologics Inc.
