Russia has claimed that its Sputnik V vaccine for the coronavirus disease 2019 is 95-percent effective based on second interim analysis of clinical trial data, its developers said on Tuesday.

The two-dose vaccine will be available on international markets for less than $10 (P500) per dose. It has an advantage in storage, as it can be stored between 2 and 8 degrees Celsius (between 35.6 and 46.4 degrees Fahrenheit).

The calculations of its effectiveness were based on preliminary data obtained 42 days after the first dose, Russia’s health ministry, the state-run Gamaleya research center and the Russian Direct Investment Fund (RDIF) said in a statement.

RDIF said the vaccine had shown 91.4 percent effectiveness 28 days after the first dose, a figure based on 39 cases.

Forty-two days later, after a second dose, data showed “an efficacy of the vaccine above 95 percent.”

“The second analysis was conducted a week after volunteers got the second dose, meaning that their bodies have partially reacted to both doses,” Gamaleya Director Alexander Gintsburg said in a statement.

The statement said 22,000 volunteers had been vaccinated with the first dose and more than 19,000 with both doses. SOVEREIGNPH
