The study revealed that SARS-CoV-2 Delta variant genomes discovered in India by April 2021 fall into four distinct groups (Delta 1,2 3 and 4), each with its own set of characteristic spike, nucleocapsid and NSP3 changes. Delta subvariant Delta 1 was estimated to be the major pandemic driver in UK, Europe and Spain as well.

Phylogenetic analysis of Israeli and Non-Israeli SARS-CoV-2 sequences revealed that the Israeli SARS-CoV-2 Strain containing P681H mutation originated from the B.1.1.50 Pangolin lineage. The B.1.1.50 Pangolin lineage had the majority of the sequences are from Israel (70%), Palestine (12%), and the UK (12%)

The study reports a newly identified SARS-CoV-2 Strain from Israel. The strain included a non-synonymous mutation in the S protein: P681H (C23604A) and additional four synonymous mutations, Nsp3:C7765T, Nsp12b: C13821T, Nsp16:T21111C, and C29545A. Phylogenetic analysis was also performed to find the lineage and transmission patterns of the viral strain.
In vitro-neutralization assays were also assessed to find the effect of mutations on viral infectivity.

Indian metadata was analyzed to associate the frequent mutations and co-mutation patterns with COVID-19 patient status (deceased, symptomatic, mild, and asymptomatic groups). Patient status was reported for only 806 sequences where 95 were marked as deceased, and 631, 49, 31 were marked as symptomatic, mild, and asymptomatic, respectively

SARS-CoV-2 spike-specific CD8+ and CD4+ T cells were detected in 70% and 100% of COVID-19 convalescent cases, respectively. In addition to the M, spike and N protein, CD4+ T cell responses were also seen against ORF3a, ORF8, nsp3, and nsp4 proteins. SARS-CoV-2 RBD-specific IgG and IgA levels correlated with CD4+ T cell responses to spike protein. SARS-CoV-2-reactive CD4+ T cells were also detected in 40%-60% of unexposed individuals suggesting cross-reactive T cell recognition. "1.)
