The Use of Yellow Fever Virus Modified by in Vitro Cultivation for Human Immunization


The response of rhesus monkeys to a subcutaneous inoculation with varying amounts of virus modified by prolonged cultivation in vitro has been studied. The tissue components of the medium consisted of chick embryo tissue containing minimal amounts of nervous tissue. The immunity produced in monkeys, as measured by the antibody titer developed, has no… (More)
