The video shows a computer-generated image of a white mouse on a blue background. The mouse is standing on its hind legs, and there is a syringe with a needle inserted into its body. The syringe is connected to a tube that leads to a small, round object with a blue and white pattern. The object appears to be a representation of a virus or bacteria. The mouse's body is shown in a cross-section, revealing the internal organs and the path of the virus or bacteria. The video is likely an educational animation explaining the process of vaccination.
