Influenza epidemics spread so rapidly and last such a short time in a given community that weekly death rates are essential to give a realistic picture of the true excess mortality that occurs during a given epidemic, the true duration of the epidemic, and other characteristics of the disease. However, in the United States, deaths from influenza and pneumonia were not generally tabulated by weeks prior to September 1918, when the great pandemic began; therefore, excess deaths in epidemics before that time can be measured by monthly data only.The earliest records now available for any State in the United States are deaths by months from influenza and pneumonia in Massachusetts. These monthly excess death rates [[annual basis) are shown in the two top sections of
figure 46 for the years 1887 to 1910, inclusive, during which time 12 small and moderate-sized outbreaks occurred; the larger ones include those with peaks in January 1890, December-January 1891-92, January 1899, and March 1900.
Figure 46 also shows influenza and pneumonia excess death rates, by months, in a group of 35 large cities in the United States from January
1910 through August 1918, during which period 3 epidemics occurred with peaks in January 1916, January 1917, and April 1918. Beginning with September 1918, data for the same group of 35 cities are shown by weeks to the end of 1921. Starting with January 1922 [[fig. 46), the record is continued by weeks for a group of 90 representative cities to the end of 1942, after which time the data are shown by weeks for a group of 56 large cities to the end of 1950, at which time 6 cities were added to make 62 cities carried until early in 1956.

Ended with WW2,because 1945 was when the vaccine was approved for use on civilians,it was used on military in the field before then,how many nowadays would be willing to go into battle after receiving a flu shot,you do not get any time outs during battle and the shot made soldiers sick,so yea they probably would have ended the war just to not get the shot.
anybody that does not agree with some are automatically considered spinning,good little dictators.
what the hell is a picuki ? Judging from the comments it appears to be a breeding ground of hate,or some seriously triggered TDS.
