title: Protection of A/He mice by a Friend virus pseudotype against challenge with Friend virus.
abstract: Prior inoculation of 7-wk-old A/He mice with the Graffi pseudotype of Friend virus protected the animals against subsequent challenge with Friend virus. Graffi leukemia virus itself did not induce protection, probably because it failed to replicate in these mice.
