Four graphs compare hospitalizations and deaths in low and high immune escape scenarios. Each plots time from Jan 2024 to Jan 2025 against counts. Lines indicate "no booster," "high-risk," and "all" vaccine recommendations.

This decision analytic model, based on plausible assumptions of immune escape and vaccine recommendations, suggests that maintaining universal #COVID19 vaccine recommendations could save more lives than targeting high-risk groups alone.

At the height of the pandemic, Americans of all political stripes were on guard against COVID Between April 2020 and June 2022, researchers found that people of different political leanings reported avoiding contact with others.

Prof. Mauricio Santillana discusses a PNAS study using 430K+ survey responses from all U.S. states (2020–22). The research reveals how personal choices, politics, and health guidance shaped COVID-19 behaviors, offering a deeper view beyond policy compliance.

🧵 1/N Our new study on the strength and durability of indirect protection from vaccines and infection-acquired immunity against SARS-CoV-2 is published this week in @naturecomms.bsky.social! We find that both vaccines and infection-acquired immunity reduce transmission to close contacts.

Our short course in infectious disease epidemiology and control is now open for applications! I am proud to be the director of this popular hands-on course which will teach you the basics of epidemic modelling in just two weeks! Apply here and spread the word! www.infectiousdiseasemodels.org

Australia’s COVID inquiry shows why a permanent ‘centre for disease control’ is more urgent than ever After initial success, Australia’s pandemic response suffered due to a lack of strong, independent, central co-ordination. We mustn’t make the same mistake twice. Here’s how a CDC can help.

Little write up just published on the process and impacts of the Scenario Modeling Hub, a huge effort it's an honour to be a part of 🎉.

Needing to move is a huge barrier to broadening representation in the sciences Science will be more inclusive and equitable when we stop expecting people to uproot their lives every few years

Imagine our profession was built so that you could advance your career without moving all the time. Isn't this a huge piece of the equity and access problem? Yes, it is.
