The Russia-made vaccine, is effective against all the variants of Covid known today, Gamaleya Centre head Alexander Gintsburg has said.
Be it UK variant or the so-called Delta variant, the antibodies that got developed after vaccination with Sputnik V can protect from all variants of COVID that are known today, he said
Sputnik V has claimed better protection against new variants. That is why its marketer Russian Direct Investment Fund has initiated a booster shot to other vaccine makers. This will be the third shot after the regular two doses of vaccines.
Pfizer is also equally effective to some extent against Delta variants. Presently, the producers are finalising the agreement in India to supply its vaccines. However, the protection is against hospitalisation. The jury is still to decide whether it can protect against the infection. However, a recent analysis of Public Health England has recently revealed that Pfizer and AstraZeneca vaccines provide high protection of over 90 per cent against hospitalisation from the Delta variant.
