Post challenge survival plots for inactivated vaccines.

Kaplan Meyer's (KM) post challenge survival percentages (PCSPs) of fish vaccinated with inactivated, water-in-oil adjuvanted vaccines made from the TAT, TTT, PAA and PTA strains, challenged at 10 weeks post vaccination with the virulent TAT strain. Mortality started on day 11 post challenge and stopped on day 27 when fish stopped dying and the PCSP curves plateaued. The challenge study was stopped on day 31. TAT and TTT groups overlap while there was a reduced survival in the PTA and PAA groups with significantly lower PCSP for the latter (p = 0.042).
