According to one embodiment, a system includes a wearable device configured to be attached to a display configured to display a display image. The wearable device features an optical component set featuring a lens, a first user operable member configured to set an adjustment value relating to a projection angle of the visual image, and a second user operable member configured to set an adjustment value relating to at least one of a color tone or a brightness of the visual image. A position of the visual image is changed by adjusting the projection angle of the visual image using the first user operable member so that the visual image is displayed at a position based on at least one of a shape or a size of the head of the user. The color tone or the brightness of the visual image is changed using the second user operable member.

The invention relates to a live-attenuated yellow fever virus strain adapted to grow on Vero cells from a parent yellow fever virus 17D substrain that is not adapted to grow on Vero cells, wherein said live-attenuated yellow fever virus strain is less neurovirulent than said parent yellow fever virus 17D substrain.

Chimeric flaviviruses that include non-coding regions, non-structural proteins, a capsid (C) protein and a portion of a premembrane (prM) signal sequence from an attenuated or wild-type dengue serotype 2 virus (DENV-2), and a portion of a prM signal sequence, a prM protein and at least a portion of an envelope (E) protein from a Zika virus (ZIKV) are described. Also described are immunogenic compositions and methods for eliciting an immune response in a subject, such as an immune response directed against ZIKV.

Embodiments herein concern compositions, methods, and uses for inducing an immune response to all four dengue virus serotypes in a child or young adult from about 1 year to about 20 years of age. Some embodiments concern compositions that can include dengue virus chimeras that, either alone or in combination with other constructs, can be used in vaccine compositions against all four dengue virus serotypes. Compositions can include constructs of more than one serotypes of dengue virus, such as dengue-1 (DEN-1) virus, dengue-2 (DEN-2) virus, dengue-3 (DEN-3) virus and/or dengue-4 (DEN-4) virus, at various concentrations or ratios to improve protection from infection in children and young adults. In certain embodiments, viruses of the formulations are limited to dengue virus serotypes. Other embodiments concern methods of administering immunogenic compositions against dengue virus that can include chimeric dengue constructs and live, attenuated dengue viruses using single, dual or other regimens.

The present invention relates to a method of generating a live attenuated vaccine. The present invention also relates to a live attenuated vaccine produced according to the method of the invention.

The present disclosure relates to Zika virus vaccines and immunogenic compositions having one or more antigens from a Zika virus (e.g., a Zika virus clonal isolate, a non-human cell adapted Zika virus, etc.), and methods of treatments and uses thereof.

The present disclosure relates to methods for inactivating a Zika virus which can be used in vaccines and immunogenic compositions. The present disclosure also relates to a method for determining the completeness of inactivation of an arbovirus preparation.

The invention relates to a live-attenuated yellow fever virus strain adapted to grow on Vero cells from a parent yellow fever virus 17D substrain that is not adapted to grow on Vero cells, wherein said live-attenuated yellow fever virus strain is less neurovirulent than said parent yellow fever virus 17D substrain.
