Spike Protein Deletions Linked to COVID-19 Surges: Preprint
Spike Protein Deletions Linked to COVID-19 Surges: Preprint
Alejandra Manjarrez | Jun 15, 2021
Researchers find that surges in COVID-19 case numbers are associated with deletions in the SARS-CoV-2 genome in an antigenic site of the spike protein. Some of these mutations are present in vaccine breakthrough infections or reinfections.
