TL;DR: A review of the literature on mutations of the SARS-CoV-2 spike protein, the primary antigen, focusing on their impacts on antigenicity and contextualizing them in the protein structure is presented in this article.

TL;DR: In this article, the authors assessed the immune responses of individuals after vaccination with the mRNA-based vaccine BNT162b22.1.7 and found that the emergence of the E484K substitution in a B.1, 1.1., 1.7 background represents a threat to the efficacy of the BNT 162b2 vaccine.

TL;DR: Recurrent emergence and significant onward transmission of a six-nucleotide out of frame deletion in the S gene, which results in loss of two amino acids: H69 and V70 is reported, which likely acts as a permissive mutation that allows acquisition of otherwise deleterious immune escape mutations.

TL;DR: In this article , the authors demonstrate substantial evasion of neutralization by Omicron BA.1 and BA.2 variants in vitro using sera from individuals vaccinated with ChAdOx1, BNT162b2 and mRNA-1273.529.
