Professor Sarah Gilbert talks about her work on viral vectored vaccines. Viral vectored vaccines combine a safe virus with a disease protein to protect against specific diseases. These vaccines have the potential to drastically improve public health. Professor Sarah Gilbert has been making and testing vaccines designed to induce T cell responses for ten years, chiefly using antigens from malaria and influenza. Based at the Jenner Institute, several of the vaccines developed in Professor Gilbert's laboratory have progressed into clinical trials.
