Russia has authorised the use of Sputnik Light — a single dose vaccine against COVID-19. Sovereign wealth fund Russian Direct Investment Fund (RDIF) said the move will pave way for the immunisation of a larger number of people in a shorter time frame. Sputnik Light is the first component of Sputnik V vaccine that has been approved by over 60 countries, including India.

CEO Kirill Dmitriev said that while the two-dose Sputnik V remains the main source of vaccination, Sputnik Light will be “exported to our international partners to help increase the rate of vaccinations in the face of the ongoing fight against the pandemic and new strains of coronavirus.” At less than $10, the vaccine will also be affordable, he said.

“It can be used as a booster shot for other vaccines. Cocktail of vaccines like Sputnik V is the way to go and work very well,” he said, adding that the booster shot will require additional trials. An RDIF statement showed that according to analyzed data taken from 28 days after the injection was administered, Sputnik Light demonstrated 79.4% efficacy. The efficacy of Sputnik V has been reported at nearly 92%.

The vaccine can elicit the development of antigen specific IgG antibodies in 96.9% of volunteers. Virus-neutralising antibodies developed in 91.67% of the volunteers on the 28th day post-immunisation. Interim results of Phase III clinical study are expected later this month.

~ To be manufactured in 10 countries

Besides Russia, Sputnik Light is to made in at least 10 other countries where RDIF has formed manufacturing partnerships with 20 producers for Sputnik V. Noting that India, China and South Korea are in the list, Mr. Dmitriev said “we will use the same production capacities,” but did not elaborate on the number of doses.

India had accorded emergency use authorisation for Sputnik V last month, following which the first consignment, comprising 1.5 lakh doses from Russia, landed on May 1 in Hyderabad. Indian companies are said to be in discussion with Dr. Reddy’s Laboratories, the marketing partner for Sputnik V in the country, to get the vaccine for their workforce and families.
