Before being relocated, Japanese Americans were vaccinated against smallpox and typhoid fever at temporary assembly centers like this one in Arcadia, California. Under the direction of Dr. Norman Kobayashi, Japanese American nurses vaccinated approximately 400 people an hour in Santa Anita Park. Evacuees were later transferred to War Relocation Authority Centers, or internment camps, for the duration of the war.
