(A) Antiorthopoxvirus CTL responses in C57BL/6 mice following footpad inoculation with various doses of ECTV-IL4(TK+) or ECTV-602(TK+). Lytic activity of splenocytes taken 7 days p.i. was determined at different effector-to-target ratios. Data shown are representative of two assays carried out in triplicate with four mice per group. Standard errors of the means at all points were <5%. (B) NK cell response in C57BL/6 mice following footpad inoculation with 10⁴ PFU of ECTV-IL4(TK+) or ECTV-602(TK+) 3 days p.i. Lytic activities at different effector-to-target ratios are shown. Data shown are representative of two assays carried out in triplicate with four mice per group. Standard errors of the means at all points were <5%.
