This study is being done to determine the safety and tolerability of a new investigational vaccine referred to as VEE IA/B V3526, which may induce production of specific antibodies in vaccinated humans, and may protect them against infection with the Venezuelan Equine Encephalitis (VEE) Virus.
Safety Objectives: 1) To determine preliminary safety, reactogenicity, and tolerability of VEE IA/B V3526 in VEE-naïve healthy volunteers after single dose subcutaneous (SC) administration; 2) To evaluate virological safety by assessing serum viremia and viral shedding in nose and throat.
Immunogenicity Objectives: 1) To assess the humoral immune response (plaque reduction neutralizing antibody titer (PRNT)) against VEE subtype IA/B after SC administration of different dose-levels of the VEE IA/B V3526 vaccine candidate; 2) To assess duration of immune response over six months after the VEE IA/B V3526 vaccination based on PRNT; and 3) To identify two suitable VEE IA/B V3526 vaccine dose-levels for future administration in dose optimization and expanded safety studies.
Exploratory Objectives: 1) To collect and store serum for future development of immunogenicity assays (e.g., ELISA) against multiple VEE subtypes IA/B, IE, IIIA, and other possible subtypes; 2) To collect and store serum for future use in the development of a passive transfer challenge model; 3) Collect VEE IA/B V3526 positive serum (Positive Control Serum) at the Day 21 visit.

A form of arboviral encephalitis endemic to Central America and the northern latitudes of South America. The causative organism (ENCEPHALITIS VIRUS, VENEZUELAN EQUINE) is transmitted to humans and horses via the bite of several mosquito species. Human viral infection may be asymptomatic or remain restricted to a mild influenza-like illness. Encephalitis, usually not severe, occurs in a small percentage of cases and may rarely feature SEIZURES and COMA. (From Joynt, Clinical Neurology, 1996, Ch26, pp9-10)
A species of ALPHAVIRUS that is the etiologic agent of encephalomyelitis in humans and equines. It is seen most commonly in parts of Central and South America.
A form of arboviral encephalitis (primarily affecting equines) endemic to eastern regions of North America. The causative organism (ENCEPHALOMYELITIS VIRUS, EASTERN EQUINE) may be transmitted to humans via the bite of AEDES mosquitoes. Clinical manifestations include the acute onset of fever, HEADACHE, altered mentation, and SEIZURES followed by coma. The condition is fatal in up to 50% of cases. Recovery may be marked by residual neurologic deficits and EPILEPSY. (From Joynt, Clinical Neurology, 1996, Ch26, pp9-10)
A subgroup of the genus FLAVIVIRUS which comprises a number of viral species that are the etiologic agents of human encephalitis in many different geographical regions. These include Japanese encephalitis virus (ENCEPHALITIS VIRUS, JAPANESE), St. Louis encephalitis virus (ENCEPHALITIS VIRUS, ST. LOUIS), Murray Valley encephalitis virus (ENCEPHALITIS VIRUS, MURRAY VALLEY), and WEST NILE VIRUS.
Gonadotropins secreted by the pituitary or the placenta in horses. This term generally refers to the gonadotropins found in the pregnant mare serum, a rich source of equine CHORIONIC GONADOTROPIN; LUTEINIZING HORMONE; and FOLLICLE STIMULATING HORMONE. Unlike that in humans, the equine LUTEINIZING HORMONE, BETA SUBUNIT is identical to the equine choronic gonadotropin, beta. Equine gonadotropins prepared from pregnant mare serum are used in reproductive studies.
