Brings to mind a little joke...
Q: How many conspiracy theorists does it take to change a light-bulb?
A: That's not funny. That's not funny at all!
Substitute any thin-skinned group you find yourself with - liberals, vegans, etc. If the faintest whiff of sarcasm has you collapsing into your fainting couch, well why is that?
Back to topic. So cool that we're sequencing now.

Using the vdbtool, we detected several clusters of isolates (unrelated to variants B.1.1.7, B.1.351, B.1.1.248, and B.1.429; Rambaut et al., 2020b; Faria et al., 2021; Tegally et al., 2020; Zhang et al., 2021)with spike mutations at sites known to be associated with resistance to antibodies against SARS-CoV-2 (Gaebler et al., 2021; Wang et al., 2021)(Table 1).This program can find clusters of isolates sharing identical sets of spike mutations, and then these patterns can be used to find potentially related isolates. One notable cluster of isolates was collected from the New York region and represents a distinct lineage, now designated as B.1.526(Figure1). There are two main branches of this lineage, one having E484K and the other including S477N, both located within the receptor-binding domain (RBD) of spike (Figure 2 and Supplementary Table S1). Regarding four of the mutations in isolates in this lineage: (1) E484K is known to attenuate neutralization of multiple anti-SARS-CoV-2 antibodies, particularly those found in Class 2 (Gaebler et al., 2021), and is also present in variants B.1.351 (Tegally et al., 2020) and P.1/B.1.1.248 (Faria et al., 2021), (2) D253G has been reported as an escape mutation from antibodies against the N-terminal domain (McCallumet al.,2021), (3) S477N has been identified in several earlier lineages (Hodcroft et al., 2020), is near the binding site of multiple antibodies (Barnes et al.,2020), and has been implicated to increase viral infectivity through enhanced interactions with ACE2 (Chen et al., 2020; Ou et al., 2020),and(4) A701V sits adjacent to the S2’ cleavage site of the neighboring protomer and is shared with variant B.1.351(Tegallyet al., 2020). The overall pattern of mutations in this lineage (Figure 2) suggests that it arose in part in response to selective pressure from antibodies. Based on the dates of collection of these isolates, it appears that the frequency of lineage B.1.526 has increasedrapidly in NewYork (Table 2).
