Russia's single dose Sputnik Light vaccine shows 78.6-83.7% efficacy among elderly in Argentina
Between the 21st and 40th day from the date of receiving the first dose of Sputnik, during the country's mass-scale civil vaccination, the infection rate among the elderlies was only 0.446 per cent.
The Russian Direct Investment Fund (RDIF) on Wednesday declared that the Sputnik Light coronavirus vaccine showed 78.6-83.7 per cent efficacy among the elderlies in Argentina.
The Ministry of Health of the Buenos Aires province (Argentina) collected real-world data from over 186,000 people aged 60-79, more than 40,000 of whom received a shot of Sputnik Light (first dose of Sputnik V), reported ANI.
Between the 21st and 40th day from the date of receiving the first dose of Sputnik, during the country's mass-scale civil vaccination, the infection rate among the elderlies was only 0.446 per cent.
An official release further said that the infection rate during the same period among the non-vaccinated adult population was 2.74 per cent.
Informing that the same formula was used to calculate the vaccine's efficacy, the official statement read, "Adjusted data weighted by age, gender and a number of other parameters among groups of vaccinated and non-vaccinated subjects demonstrated comparable efficacy of the Russian vaccine - 78.6 per cent."
Reportedly, the positive official data may potentially lead Argentina to use the Sputnik jab more widely among its population during the vaccination campaign.
Kirill Dmitriev, CEO of the RDIF, said: "The publication of independent data in Buenos Aires province confirms high efficacy of the Russian vaccine for senior citizens who are in a high-risk group. An efficacy level of near 83.7 per cent is higher than that of many two-dose vaccines."
"As the report of the Ministry of Health of the province has demonstrated, vaccination with Sputnik Light (the first component of the Sputnik V vaccine) can significantly reduce the number of infections and hospitalizations. We plan to continue cooperating with colleagues in Argentina for further data on the use of the Russian vaccine," Dmitriev added.
According to the official release, the efficacy of Sputnik Light stands at 79.4 per cent. It is based on the analysis of data, made available about the coronavirus infection rate in Russia.
