NOTE: As of 24 Jun 2021, Chriona data has identified the mutation K417N mutation present in the Delta Plus variant (Pango AY.1) with ~24 points. Since this data was taken on 23 May 2021, newer mutations can only be screened with newer data from GISAID/NCBI.
Current SARS-Cov-2 variants and lineages are identified by PANGOLIN.
Emerging variants show resistance against vaccines previously produced, with neutralising effects.
Chirona attempts to find hotspots of mutations in SARS-CoV-2 Pango lineages and generate permutations of sequences that can adapt to said mutations.
