Natalia Pshenichnaya, senior epidemiologist at the national consumer protection watchdog Rospotrebnadzor, said earlier today that the long-term effectiveness of the Sputnik V vaccine could render future booster doses obsolete.
In a subsequent statement on Rospotrebnadzor’s website, Pshenichnaya said his comments were “misinterpreted”.
“What we wanted to say is that revaccination with the EpiVacCorona and KoviVak vaccines is possible after 1 to 2 years of vaccination. [with Sputnik V]She said, referring to the other two Russian-made jabs.
The confusion surrounding revaccination comes amid Russia’s already slow vaccination campaign, with around 4 million out of 146 million Russians having received both doses within two months of the start of the deployment.
President Vladimir Putin is expected to receive one of Russia’s Covid-19 vaccines on Tuesday – albeit out of public view – in hopes of overturning Russians’ skepticism of the vaccines.
A recent independent poll showed that nearly two-thirds of Russian respondents called Covid-19 an artificial biological weapon and less than a third were ready to be vaccinated.
A peer-reviewed study published last month rated the effectiveness of Sputnik V at 91.6%. To date, more than 50 countries have approved Sputnik V.
