Vaccination of guinea pigs with an hsp60-hsp70 protein vaccine mixture. (A) Bacterial load in lungs 30 days after aerosol challenge. (B) Mean survival. Note that none of the BCG-vaccinated animals had died when the experiment was stopped at 27 weeks. (C) Mean weight gain. For panels A to C, n = 4 and error bars indicate standard errors of the means. (D) Weight loss of individual animals. Open squares, adjuvant controls; closed squares, hsp60-hsp70-vaccinated animals.
