COVID 19: As the world is fighting with Coronavirus pandemic, another newly emerged cause of concern is Delta variant of COvid 19. Recently, the World Health Organization has expressed apprehensions over the existence of Delta variant Covid-19, is reducing the efficacy of the existing Covid 19 vaccines in the world.
A new mutant of the variant was first found in Indian states- Maharashtra, Kerala and Madhya Pradesh.
Following this, the health ministry asked Maharashtra, Kerala, Madhya Pradesh to excercise caution.
The Covishield of Bharat Biotech’s Covaxin and Serum Institute of India are effective against the Delta variant, the health ministry has said.
Speaking to a leading daily, Union health secretary Rajesh Bhushan said that both the vaccines—Covishield and Covaxin, (Sputnik joined later) are being administered in India, are effective against Delta. But to what extent and what is the proportion of antibody titers produced by these vaccines will be shared soon.
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.
