MOSCOW, Aug 18 (Reuters) - Russia's single-dose Sputnik Light vaccine against COVID-19 has demonstrated 93.5% efficacy in Paraguay, with data taken from the South American country's vaccination campaign, the Russian Direct Investment Fund (RDIF) said on Wednesday.
Developed by Moscow's Gamaleya Institute, Sputnik Light had shown 79.4% efficacy when it was first authorised for use in May. read more
The RDIF, citing data from Paraguay's health ministry collected by July 30, said the vaccine had proved highly effective among more than 320,000 people.
"The use of the single-component vaccine Sputnik Light allows the Paraguayan authorities to shorten vaccination periods for the population and speed up the formation of collective immunity," RDIF head Kirill Dmitriev said in a statement.
