<jats:title>ABSTRACT</jats:title>
<jats:p>Influenza virus hemagglutinin consists of a highly variable and immunodominant head domain and a more conserved but immunosubdominant stalk domain. We introduced seven N-linked glycosylation sites in the hemagglutinin head domain to shield the immunodominant antigenic sites. The hyperglycosylated hemagglutinin enhanced stalk-directed seroreactivity while dampening the head response in immunized mice. Upon influenza virus challenge, mice vaccinated with the hyperglycosylated hemagglutinin were better protected against morbidity and mortality than mice receiving the wild-type hemagglutinin.</jats:p>
