Type I interferons play a critical role in both innate and adaptive immunity through the stimulation of the IFNAR1 which initiates interferon signaling in response to viral and bacterial infections. However, abnormal interferon signaling is associated with human diseases, such as lupus. The present invention discloses six hybridomas that produce mouse monoclonal antibodies specific for the extracellular domain of human IFNAR1. Two of the monoclonal antibodies are able to bind IFNAR1 and reduce interferon signaling.

Vaccines and therapies to prevent and treat Norovirus infections do not exist, despite the worldwide prevalence of Norovirus infections. Outbreaks of human gastroenteritis attributable to Norovirus commonly occur in group setting, such as hospitals, nursing homes, schools, dormitories, cruise ships and military barracks.

The invention, a stabilized recombinant prefusion F protein (pre F), is a candidate subunit vaccine for Respiratory Syncytial Virus (RSV). Pre-F is stabilized in the prefusion conformation and displays epitopes not present in postfusion F protein. Several potent RSV neutralizing antibodies bind pre F, but not postfusion F. Therefore, immunization with pre F may elicit an immune response superior to the response generated by postfusion F.

Chikungunya virus (CHIKV) is mosquito-borne alphavirus endemic in Africa, India, and Southeast Asia. In 2013 CHIKV infection has also emerged in the Caribbean and a pandemic of CHIKV has re-emerged in the Philippines following Typhoon Haiyan. Currently, there is no vaccine available for the prevention of CHIKV infection and no specific therapy exists to treat the illness.

Epstein-Barr Virus (EBV) is the causative agent of infectious mononucleosis and is associated with certain types of cancers, such as Hodgkin's lymphoma, Burkitt's lymphoma, gastric carcinoma, and nasopharyngeal carcinoma. There are currently no vaccines against EBV on the market and there is only supportive treatment available for EBV infection.

Hermansky-Pudlak Syndrome type-1 (HPS-1) is a rare genetic disorder that affects around 1 in 500,000 people worldwide and 1 in 1,800 Puerto Ricans. Patients with HPS-1 display oculocutaneous albinism, bleeding due to platelet abnormality, and pulmonary fibrosis. Those that develop pulmonary fibrosis often succumb and live no more than a decade after early onset of breathing problems.

Zika virus (ZIKV) is a flavivirus transmitted by mosquitos that is strongly linked to neurological complications including Guillain-Barré syndrome, meningoencephalitis, and microcephaly. The association between active ZIKV infection during pregnancy and microcephaly and intrauterine growth retardation in the fetus has been confirmed in murine models of ZIKV infection.

Many members of the Flaviviridae family are emerging and reemerging human pathogens that have caused outbreaks of devastating and often fatal diseases and represent a serious public health problem on a global scale. There is no single attenuation strategy that exists which is sufficient to prepare a safe, efficacious and immunogenic live attenuated virus vaccine that will work universally for Flaviviridae.

An arthropod-borne virus, Zika virus (ZIKV), has recently emerged as a major human pathogen. Associated with complications during perinatal development and Guillain-Barré syndrome in adults, ZIKV raises new challenges for understanding the molecular determinants of flavivirus pathogenesis. This underscores the necessity for the development of a reverse genetic system based on an epidemic ZIKV strain. This technology relates to the generation and characterization in cell cultures of an infectious cDNA clone of ZIKV isolated from the 2015 epidemic in Brazil.

This application claims live attenuated Zika viruses and vaccines, attenuated chimeric Zika viruses and vaccines, and multivalent immunogenic compositions comprising Zika vaccines and vaccines for other flaviviruses. The chimeric Zika viruses claimed include a first nucleotide sequence encoding at least one structural protein from a Zika virus (ZIKV), a second nucleotide sequence encoding at least one nonstructural protein from a first flavivirus, and a third nucleotide sequence of a 3' untranslated region from a second flavivirus.
