NEJM: In two coronavirus vaccine breakthrough cases “examination of the SARS-CoV-2 sequences revealed that both patients were infected with variant viruses” .. “neither sequence precisely fit any known clade”
Examination of the SARS-CoV-2 sequences revealed that both patients were infected with variant viruses. Rapid identification of sequence variants by targeted PCR amplification showed that neither sequence precisely fit any known clade. Some of the substitutions in Patient 1 (T95I, del144, E484K, A570D, D614G, P681H, and D796H) were shared with B.1.526 (T95I, E484K, and D614G6), and three substitutions were shared with Patient 2 (in whom the variants T95I, G142V and del144, F220I, R190T, R237K, R246T, and D614G were detected).
