Very low levels of IFN-γ were observed in the positive control immunized with EB (32), indicative of local control of the infection, while high levels of IFN-γ were detected in the groups vaccinated with MOMP-tNLP+CpG+FSL-1 by the i.m. route only and the negative controls immunized with tNLP+CpG+FSL-1 or PBS (2431, 2613 and 3002, respectively). Here, IFNG is linked to infection.
