Influenza Research in the Soviet Union—1974	1974-12-17		.txt	text/plain	5186	258	45	A long historical tradition for the use of livevirus vaccines in the Soviet Union dates from Smorodintsev's experimental infection of volunteers with influenza virus in 1937 [2] . Since registered morbidity rather than a more direct measure of real influenza-ARD morbidity is used, the model probably has more applicability for health planners, who need to anticipate increased requirements for delivery of health care associated with epidemics, and for industrial organizations that face future production losses, than for those concerned with anticipating changes in the health status of the population per se. Although data from the morbidity registration system in the Soviet Union provide the basic information for this model, data from the 52 All-Union reporting centers appear to be used as well, particularly for obtaining early warning of the location of the initial epidemic outbreak in the country.	./cache/cord-293299-gdew0ueo.txt	./txt/cord-293299-gdew0ueo.txt
