Neutralising antibody titre after i.v. (♦) or IHP (▴) with AV1.0CMV determined as described in Materials and methods section. Antibody titres after IHP were significantly lower compared to i.v. from day 3 up to day 23 (P⩽0.05). On day 6 after treatment a mean peak titre could be measured: 352 after i.v. injection vs. 27 after IHP (P=0.03). Mean values of five animals±s.d. are shown.
