In its fifth 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.


  • Update on mobilisation of raw reads, now totaling sequencing data sets from 679,693 viral raw read sets from 66 countries, a 23% increase since the previous report.
  • The variant nomenclature has been updated, and tables on countries depositing data on VOC and VOI have been included.
  • The variant calling workflow for the Oxford Nanopore data has been implemented and 39,628 samples of the total 93,581 have been processed so far.
  • A description of the workflow for generating phylogenetic trees and visualization, as well as how to use this for selecting datasets for individual download, has been included.
