To assess the impact of glycosylation on the immunogenicity of an HA-expressing DNA vaccine, a series of plasmid vaccine constructs that differed in the presence of potential glycosylation sites at amino acid residues 154-156, 165-167, and 286-288 were used to immunize BALB/c mice," scientists in...
