1977 Russian flu

The 1977 Russian flu was an influenza pandemic that was first reported by the Soviet Union in 1977 and lasted until 1979.^[1]^[2] The outbreak in northern China started in May 1977, slightly earlier than that in the Soviet Union.^[3]^[4] The pandemic mostly affected a population younger than 25 or 26 years of age,^[1]^[5]^[6] and was described as mild.^[6] It was caused by an H1N1 flu strain which highly resembled a virus strain circulating worldwide from 1946 to 1957.^[1]^[2]^[5]^[6] Genetic analysis and several unusual characteristics of the 1977 Russian flu have prompted many researchers to say that the virus was released to the public through a laboratory accident,^[4]^[5]^[7]^[8]^[9]^[10] or resulted from a live-vaccine trial escape.^[5]^[11]
