VOICED : Creadores de vacuna Sputnik reivindican "fuerte protección" contra ómicron

The creators of the Russian Sputnik V vaccine assert its superior efficacy against the Omicron variant compared to Pfizer, based on a study by the Italian Spalanzani lab and the Gamaleya Center.

In Latin America, Argentina was the first to approve Sputnik V, which is now used in 69 countries, including Mexico, Guatemala, Venezuela, and Bolivia.
