Comparison of vaccination regimens. a) Time of tumour appearance in various vaccinated groups. The regimen 2 and 3 resulted in prolonged tumour free periods (p regimen 1 vs 2 < 0.01, regimen 1 vs 3 < 0.01, and regimen 2 vs 3 = 0.4). b) Mean survival in various vaccination regimens (p regimen 1 vs 2 = 0.4, regimen1 vs 3 = 0.04, regimen 2 vs 3 = 0.04). Data shown only for the phPSA vaccinated mice in all three regimens. Errors bars represent SE.
