Glycosyltransferases in the endoplasmatic reticulum are responsible for the attachment of numerous high-mannose N-glycans on the SARS-CoV-2 spike protein. After virion assembly and release these glycosidations are required for fusion with host cells (Watanabe et al, 2020, Breuer et al, 2001).

O-glycosylations do occur on the Spike protein with an average overall frequency per site of less than 50 percent (Sanda et al, 2020).
