New Delhi: Dr Reddy’s Laboratories said Monday the Drugs Controller General of India (DCGI) has granted approval to the single-shot ‘Sputnik Light’ vaccine for restricted use in emergency situation in India. Sputnik Light is a one-dose vaccine and the same as the first component –recombinant human adenovirus serotype number 26 (rAd26) – of the two-dose Sputnik V vaccine, Dr Reddy’s said in a statement.
In September 2020, the drug major had partnered with the Russian Direct Investment Fund (RDIF) to conduct clinical trials of Sputnik V. It was done later on Sputnik V was distributed in India by Dr Reddy’s. In April 2021, the DCGI granted approval to the two-dose Sputnik V vaccine for restricted use in emergency situation in India.
Following its phase III clinical trial of the single-shot Sputnik Light vaccine in India, the Hyderabad-based drug major had submitted its application for approval to the DCGI in December 2021, in addition to data from clinical trials in Russia.
The standalone Sputnik Light vaccine is the latest vaccine to be approved by the DCGI as part of India’s national inoculation effort against Cocid-19.
Sputnik Light has been approved in over 30 countries around the world including Argentina, UAE, Philippines and Russia.

Earlier this year, an independent comparative study conducted by the Spallanzani Institute in Italy showed that Sputnik V demonstrates strong protection against the Omicron variant, with over two times higher virus neutralising activity compared to the Pfizer vaccine.
The data supports the results of the recent laboratory study by the ‘Gamaleya Centre’ demonstrating that Sputnik V induces robust neutralising antibody response to the Omicron variant, further strengthened by Sputnik Light as a booster.
In a separate statement, RDIF CEO Kirill Dmitriev stated that the authorisation of Sputnik Light in India is another major step in successful cooperation between Russia and India in the fight against Covid-19.
“Sputnik Light has proven to be safe and effective both as a standalone vaccine and a universal booster shot to vaccines of other producers, helping to induce stronger immune response as compared to two shots of the same vaccine. The heterologous boosting approach using Sputnik Light is the solution to increase efficacy and duration of other vaccines, including against Omicron variant,” said Dmitriev.
