Model of a Flu Virus

Caption

This is a 3-D print of influenza virus. The virus surface (yellow) is covered with proteins called hemagglutinin (blue) and neuraminidase (red) that enable the virus to enter and infect human cells. In this study, Worobey and his collaborators show that the type of flu virus we first are exposed to as children determines which types we are protected from for the rest of our lives.
