Abstract
BackgroundThe objective of this study was to investigate whether the use of live attenuated varicella zoster virus (VZV) MAV vaccination can efficiently induce VZV antibody production in naive rhesus monkeys as an approach to prevent simian varicella virus (SVV) reactivation in animals immunosuppressed for transplantation studies.ResultsClinically available human VZV vaccine was used to induce the production of anti-VZV antibodies in rhesus monkeys. A vial of the vaccine was subcutaneously injected at 0 week, and the second and third vaccination was performed at 5 and 6 weeks by intratracheal inoculation. The titer of anti-VZV IgG was assessed at 0, 2, 4, 6, and 7 weeks. At 2 weeks, 3/16 were seropositive for VZV IgG. At 6 weeks, 9/16 were shown to be seropositive. At 7 weeks, 16/16 were found to be seropositive.ConclusionsThe VZV vaccine via intratrachael inoculation was shown to induce VZV IgG humoral immunity in rhesus monkeys and may be important immunosuppressed macaques for transplantation studies. Although the humoral immunity produced is an important finding, further studies will be necessary to confirm possible protection and it could protect probably against SVV infection in rhesus monkey.

SVV was suspected because of the vesicular skin rash, and SVV viremia was confirmed by qPCR
We found that SuduVax (VZV MAV strain), especially via intratracheal inoculation, was able to induce VZV IgG production
Summary
The objective of this study was to investigate whether the use of live attenuated varicella zoster virus (VZV) MAV vaccination can efficiently induce VZV antibody production in naive rhesus monkeys as an approach to prevent simian varicella virus (SVV) reactivation in animals immunosuppressed for transplantation studies. Simian varicella virus (SVV) in Old World monkeys causes epizootic erythematous disease, which is characterized by fever, vesicular skin rash, hepatitis, and high morbidity and mortality [1]. Outbreaks of SVV occur sporadically in facilities housing nonhuman primates and can result in a loss of valuable research animals [1]. When SVV infection outbreaks occur, prompt diagnosis and antiviral treatment are important for patients at an.
