In conclusion, GS-4774 was safe and well-tolerated in healthy subjects with injection-site reactions being the most frequently reported adverse events. GS-4774 was immunogenic and both weekly and monthly regimens led to rigorous immune responses at all doses evaluated. Further evaluation of GS-4774 is ongoing in patients with chronic HBV infection. Claire Coeshott, David Apelian, and Timothy Rodell were involved in the conception and design of the study and on data acquisition, analysis, and interpretation. Anuj Gaggar, Gong Shen, G. Mani Subramanian, and John G. McHutchison participated in the analysis and interpretation of data. All authors critically reviewed draft versions of the manuscript

and approved the final version. The authors would like to thank the SNS-032 manufacturer subjects and staff who participated in the study as well as Dr. Mrinalini

Kala at the University of Arizona who performed PBMC isolation.

“African horse sickness virus (AHSV) is the causative agent of African horse sickness (AHS) which is lethal for up to 90% of

infected domestic horses [1]. AHSV infections science of zebras and donkeys are less severe and mostly cause mild clinical symptoms or an asymptomatic infection. These equids are carriers of AHSV, which is transmitted by Culicoides midges, in particular by C. imicola in endemic areas [1] and [2]. It is believed that the distribution of AHSV is associated with the presence of these competent vectors. Currently, AHSV is endemic in tropical and sub-Saharan Africa, but sporadic cases and short-term epidemics in North Africa and Middle-East have been reported in the mid-20th century. In 1987, an outbreak of AHSV-4 on the Iberian Peninsula, which was extended for a few years in Spain and spread to Portugal and Morocco indicating that AHSV had overwintered and spread by European Culicoides midges [1] and [3]. The serogroup AHSV within the genus Orbivirus of the Reoviridae family consists of nine serotypes (AHSV-1 – AHSV-9). The virus particle contains ten genome segments of double-stranded RNA (dsRNA) encoding seven structural proteins (VP1-VP7). Additionally, at least three non-structural proteins (NS1-NS3) are synthesized in virus infected cells.
