VEO submits the fourth report on mutations and variation in publicly shared SARS-CoV-2 raw sequencing data.

In its fourth report to the European Commission, VEO Consortium members summarize mobilisation and analysis of SARS-CoV-2 sequence data submitted to the European COVID-19 Data Platform in the context of the VEO project, which aims to develop tools and data analytics for pandemic and outbreak preparedness.

Summary: 

  • Update on mobilisation of raw reads, now totaling sequencing data sets from 552,185 viral raw read sets from 64 countries, a 5% increase since the previous report, as of 26 April 2021 (data freeze 19 April).
  • Information on the B.1.617.2 variant and the B.1.621 variant was added.
  • A decision was made on how to perform variant calling of the Oxford Nanopore data, the current workflow will be adjusted soon after which the backlog of Oxford Nanopore data can be processed. We will continue to further benchmark Oxford Nanopore variant calling.
