Sputnik V COVID-19 vaccine
Sputnik V (Russian: Спутник V, the brand name from RDIF) or Gam-COVID-Vac (Russian: Гам-КОВИД-Вак, the name under which it is legally registered and produced) is an adenovirus viral vector vaccine for COVID-19 developed by the Gamaleya Research Institute of Epidemiology and Microbiology in Russia. It is the world's first registered combination vector vaccine for the prevention of COVID-19, having been registered on 11 August 2020 by the Russian Ministry of Health.

Gam-COVID-Vac was initially approved for distribution in Russia and then in 59 other countries (as of April 2021) on the preliminary results of Phase I–II studies eventually published on 4 September 2020. Approval in early August of Gam-COVID-Vac was met with criticism in mass media and discussions in the scientific community as to whether approval was justified in the absence of robust scientific research confirming safety and efficacy. A large-scale Brazilian study from Dec. 2020 to May 2021 confirmed its effectiveness and safety, as of Oxford–AstraZeneca's, i.e. above Sinopharm BIBP's.
Emergency mass-distribution of the vaccine began in December 2020 in countries including Russia, Argentina, Belarus, Hungary, Serbia, Pakistan (in limited quantities), the Philippines (in limited quantities), and the United Arab Emirates. The Sputnik V is currently registered and certified in 71 countries. However, as of April 2022 less than 2.5% of the people vaccinated worldwide have taken a Sputnik V dose. In early 2022, as a result of the 2022 Russian invasion of Ukraine, the United States and other countries placed RDIF on the list of sanctioned Russian entities and people, significantly reducing Sputnik V's future commercial prospects.
The Gam-COVID-Vac vaccine itself is available in two forms: frozen (vaccine storage: below −18 °C) and liquid (vaccine storage: from +2 to +8 °C, produced a little). In addition to the main vaccine, vaccines and its derivatives were registered: Gam-COVID-Vac-Lyo (Russian: Гам-КОВИД-Вак-Лио, no data on use), Sputnik Light (Russian: Спутник Лайт, used for revaccination, as well as vaccination of foreigners in Russia), Gam-COVID-Vac-M (Russian: Гам-КОВИД-Вак-М, for vaccination of adolescents 12–17 years old).
