🦠 Clinical Trial Update 🦠

McMaster University's inhaled COVID-19 #vaccine safely generates immune responses associated with protection in the lungs, according to phase-1 clinical trial data published in Nature Communications. Our inhaled vaccine is now in ongoing phase-2 trials. Learn more 👇

IIDR researchers have discovered that a single gene in Yersinia pestis — the bacteria that causes bubonic #plague — was responsible for keeping pandemics like the Black Death burning for hundreds of years. Learn more about this evolutionary phenomenon in our all-new explainer video. #IDSky

Mark Loeb receives prestigious lifetime achievement award for infectious disease research McMaster Professor has received a 2025 Lifetime Achievement Award from the Association of Medical Microbiology and Infectious Disease Canada.

Exciting work by @gdwantibiotics.bsky.social and team, with a new molecule that is toxic to bacteria - a promising new candidate for new antibiotics!

Drug discovery: McMaster researchers find new antibiotic YouTube video by McMaster University

The last time a new class of antibiotics reached the market was nearly three decades ago — but that could soon change, thanks to a discovery by researchers at McMaster University.

Heeding the lessons of COVID-19 in the face of avian influenza COVID-19 exposed the many ways in which we were ill-prepared to prevent and respond to pandemics. Are we applying those lessons to prevent a bird flu pandemic?

In a new op-ed for @theconversationca.bsky.social, IIDR Director Matthew Miller writes that as "we stand on the brink of an avian influenza pandemic," lessons learned from COVID-19 can help us avert disaster — but only if we act on them. #IDSKy #H5N1 #BirdFlu
