Sputnik Light is the first component (recombinant human adenovirus serotype number 26 (rAd26)) of Sputnik V – the world’s first registered vaccine against coronavirus.

The Sputnik Light vaccine, like Sputnik V, is based on a proven well-studied human adenovirus vector platform; these vectors cause the common cold and have peacefully coexisted with humanity for millenia.

Safety of Sputnik Light, as the first component of Sputnik V, was confirmed by real-world data from UAE, Bahrain, Argentina, Russia, Mexico, Serbia, San Marino, Philippines, Libya, Paraguay, Hungary, Azerbaijan and Belarus.

Sputnik Light has a long-lasting protection, which even increases over 4-6 months following the vaccination.

Many other vaccines showed dramatic decrease in efficacy against Delta variant to below 50% within the same time period.

Sputnik Light safety was confirmed by real-world data from multiple countries and by over 20 publications in the leading international scientific journals.
