Few Russian scientists are testing the effectiveness of revaccination with the Sputnik V shot to protect against new mutations of the Coronavirus. The results produced were strong, researchers said on Saturday.
President Vladimir Putin has already ordered for a review of Russian-produced vaccines for their effectiveness against new variants by. With the review ordered before 15th March, results of the trial are expected to be published soon.
A recent study carried out by the Gamaleya Centre in Russia showed that revaccination with Sputnik V vaccine is working very well against new coronavirus mutations, including the UK and South African strains of coronavirus,” said Denis Logunov, a deputy director of the centre, which developed the Sputnik V shot.
So-called viral vector shots such as Sputnik V use harmless modified viruses as vehicles, or vectors, to carry genetic information that helps the body build immunity against future infections. The revaccination used the same Sputnik V shot, based upon the same adenovirus vectors.
