The family of 32 known RNA alphaviruses are present globally, are transmitted by mosquitos, and can cause human disease most commonly arthritogenic or encephalitic in presentation, the latter of which has a fatality rate as high as 35% to 75% depending on host co-morbidities. Previous studies have demonstrated antibody-mediated protection against specific types of alphavirus infections, but broad-spectrum protection against multiple alphavirus has only been reported recently. Even more, the vaccine-mediated elicitation of monoclonal antibodies (MAbs) has yet to be demonstrated until now.
