Adenoviruses have emerged as a promising gene-delivery platform for therapeutic and vaccine purposes. But many people have preexisting immunity to human adenoviruses, such as those shown here, which can cause a variety of common illnesses. Using a delivery system based on a modified bovine adenovirus, researchers hope to develop an effective COVID-19 vaccine that avoids issues associated with vector immunity.
