For President Woodrow Wilson, the pandemic was a case of first impression. The country was accustomed to 100,000 deaths a year from the flu. Widespread use of vaccines were not common. It wasn’t that Wilson was restrained about using federal power, he simply had far less precedent to lean on, and a much higher priority in the war effort.
