Using adjuvanted Ad5-ZGP as a
candidate vaccine, our aim is to determine whether immunization
of contact gps 4 weeks before direct exposure to an untreated,
infectious animal is effective at protecting the vaccine recipient
from EBOV transmission. Survival and clinical symptoms, in addition
to viremia and EBOV shedding of contact animals were monitored
to confirm vaccine efficacy. Since the specific antibody
response statistically correlates with survival from EBOV (Wong
et al., 2012), total IgG and neutralizing antibodies were quantified
before and after challenge from contact animals as an additional
indicator of vaccine-induced protection.
