Sputnik Light has proven effective against all new strains of coronavirus, as demonstrated by the Gamaleya Center during laboratory tests, a press release from RDIF had said on May 6.
Sputnik V is currently manufactured in India and being sold by Dr Reddy's Laboratories under Emergency Use Authorisation route.
This is the first batch of the second component produced and supplied by the company in India, the drug firm and the Russian Direct Investment Fund (RDIF) said in a joint statement.
There is no need to check the antibody levels post-taking the vaccine as some vaccines evoke T-cell immunity (long-term memory of the immune response), says Dr. Subrata Das.
The Deputy Director of Health Services Dr S Senthilkumar said that 10 private hospitals in the district are authorised to administer Covid vaccines. Of them, only two hospitals offer Sputnik V.
Speaking at the launch of the vaccine, Dhami said by December this year, the state government will achieve its target of 100 per cent vaccination.
Production in India is expected to come fully onstream in September and RDIF expects India to become a major production hub for the Sputnik V vaccine.
Both shots use a similar technology, employing a harmless virus to deliver genetic material from the spike protein of COVID-19 into the body.
Of the over 40 crore Covid-19 vaccine doses administered in India, it is not clear how many were given in private hospitals. Sources said it could be in the range of 7-8 crore.
Manipal Hospitals, Vijayawada, started administering Sputnik V vaccine as part of its COVID-19 vaccination drive.
The high antibody levels after a single Sputnik V dose in naive participants suggest a benefit of delaying second dose administration to increase the number of people vaccinated.
'The first batch of Sputnik vaccine is expected to be produced at SII's facilities in September,' RDIF said in a statement.
The parties intend to produce over 300 million doses of the vaccine in India per year, RDIF said in a statement.
In a tweet on Monday night, the city-based drug maker said it will strengthen the commercial rollout of Sputnik V in the coming weeks.
In total, agreements with partners in India provide for the production of more than 850 million doses of Sputnik V per year, the statement said.
