  • Publication number: 20230406910
    Abstract: Provided is a method for producing an influenza HA split vaccine which produces an antibody that binds to a HA stem region of influenza, the HA stem region being less likely to cause antigenic variation, An influenza HA split vaccine is subjected to an acidic treatment. Through the acidic treatment, an influenza HA split vaccine which produces an antibody that binds to a LAH of the HA stem region is obtained. This influenza HA split vaccine has an excellent protective ability against infection of other influenza viruses of different antigenicity.

  • Patent number: 11740688
    Abstract: A virtual space experience system capable of preventing unintentional contact between players without inhibiting a sense of immersion is provided. A virtual space image determination unit 35 of a VR system S causes an image of a virtual space to be perceived by a second player to include an image in which a first avatar corresponding to a first player moves so as to generate a gap in a correspondence relationship between coordinates of the first player and coordinates of the first avatar when a trigger event is recognized, and causes the image of the virtual space to be perceived by the second player to include an image of a second avatar corresponding to the second player and a third avatar corresponding to the first player after the recognition. An avatar coordinate determination unit 34 determines coordinates of the third avatar based on the coordinates of the first player.
