^aNET = Reduction in tick numbers = Total number of ticks from the immunized group / Total number of ticks from the control group.
^bEWPF = Reduction in weight of eggs per female = (Total weight of eggs from the immunized group/ Total number of ticks from immunized group) / (Total weight of eggs from the control group / Total number of ticks from control group).
^cH = Reduction in hatchability = % hatch from immunized group / % hatch from control group.
^dEff = % Overall efficacy compared to control =100 [1-(NET x EWPF x H)].
