Protective Properties against Yellow Fever Virus in the Sera of the Offspring of Immune Rhesus Monkeys

[摘要] Five baby monkeys born of mothers immune to yellow fever were all found to have in their sera protective properties against yellow fever. This was the case when they were still subsisting on their mother's milk. In two instances, in which the baby monkeys had been separated from their mothers for three weeks, the sera of the offspring showed no evidence of protective properties.
