Immunization to inoculated infectious ectromelia can be provided by intraperitoneal or intravenous administration of vaccine virus Ankara strain in suitable dilution. The degree of immunization depends on the dose administered. After peritoneal injection of vaccine virus, distinct immunization can be demonstrated within three days and immunity is established after six days. Five months after a single injection of vaccine virus, more than 50 of the test animals still show immunity to a massive injection of ectromelia virus.
