The technology of using adenoviral vectors as vector vaccines has been developing since the 80s of the last century, and numerous studies have shown the effectiveness and safety of this technology.
Currently there are about 165 different vaccines for COVID-19 being developed around the world. The main types of vaccines include: viral vector-based vaccines, virus-based, nucleic acid-based and protein-based vaccines. Russian adenovirus vector-based vaccine was registered by the Russian Ministry of Health on August 11 and became the first registered COVID-19 vaccine on the market. The announcement created a so-called "Sputnik moment" for the global community.
In 1957 the successful launch of the first space satellite by the Soviet Union reinvigorated space research around the world. The new Russian COVID-19 vaccine is therefore called Sputnik V.
