“…As cost‐effective, carbon‐neutral factories, plants are attractive platforms for the production of biopharmaceuticals, vaccines, and other high‐value bioproducts using advanced biotechnological tools. During the past decades, considerable efforts have been made towards using plants as production hosts for vaccines against diseases such as Alzheimer’s disease (Ishiura and Yoshida, 2019 ), cancer (Wong‐Arce et al., 2017 ), dengue fever (van Eerde et al., 2019 ), hepatitis B (Dobrica et al., 2017 ; Fedorowicz‐Stronska et al., 2016 ; Pniewski et al., 2018 ) or poliomyelitis (Chan et al., 2016 ). However, the immunogenicity of plant‐made antigens varies considerably and can be influenced substantially by the plant‐specific protein glycosylation.…”
