Nextstrain plays a critical role tracking the spread of SARS-CoV-2, and is open-sourcing the data to increase epidemiological understanding and improve public health responses. Trevor Bedford, a scientist at the Fred Hutchinson Cancer Research Institute who studies the spread and evolution of viruses, co-developed Nextstrain. Trevor and his team just posted their analysis of vaccine distribution in 2021 and antigenic drift of SARS-CoV-2 (read the full thread by @trvrb on twitter). From Trevor: “In the near-term, vaccine efficacy will likely not be reduced but it is important to continue tracking mutations and updating as we learn more.”
