This week, we sit down with Brian Renda, Programme Director for the Built Environment, and Victoria Slaughter, PPE Director at Blueprint Biosecurity, to explore a question that fundamentally challenges how we think about pandemic preparedness: What if the single biggest barrier to preventing the next pandemic isn't our lack of scientific knowledge or technology—but our complete failure to recognise that preparing for respiratory pandemics requires pathogen agnostic infrastructure deployed before emergencies strike, high quality respirators accessible to everyone who needs them, and a fundamental shift from accepting pandemics as inevitable to building systems where outbreaks are contained before they spiral into global catastrophe?

Key Topics Discussed:

• Post COVID Reality and the Challenge of Sustained Preparedness: It is incredibly hard to plan and respond to threats that are not immediately in front of you. During the pandemic, the risk was visible and destructive. Now that attention has shifted, it is difficult to maintain focus on the next pandemic when we do not know if it will happen in one year, ten years, or a hundred years. Blueprint's role is to advance our overall state of readiness so that while we may not be able to stop outbreaks from happening, we can stop them from progressing into pandemics. History has shown we cannot predict when the next large event will be. We must be in preparation mode, but we cannot assume we have infinite time. The earlier preparations are done, the better protected we are.
• The Mask Versus Respirator Problem: So much of the confusion and misinformation during COVID stemmed from a lack of access to high quality products. There is an enormous difference between a mask and a respirator. A respirator filters the air a user breathes to a regulatory standard such as N95 or FFP3. A surgical mask or cloth mask does not. Surgical masks are designed to catch large particles and spit from a wearer's mouth in sterile environments. They are not designed to filter aerosols or airborne particles. The lack of any standard for cloth masks meant protection was wildly variable. Some offered almost no protection at all. When people are given high quality respirators with known efficacy, they do not have to wonder if something is protecting them. That changes everything.
• Stockpiling Strategy and the Lessons from COVID Waste: Respirators do expire, but the standards are extraordinarily high because these products are a person's last line of defense. Most respirators last longer than their expiration date, but manufacturers want to ensure even the final 0.1 percent that may no longer be good does not reach a person. Some respirators have shelf lives upwards of 20 years. That is very different from products that expire every three years. Smart stockpiling means filling warehouses with products that are ideal for long term storage and allowing for product rotation. Post COVID, many stockpiles are starting to disappear simply because products are expiring.
• The Built Environment Programme and Pathogen Agnostic Technologies: Blueprint focuses on interventions that are pathogen agnostic, work in occupied spaces, have promising safety and efficacy profiles, integrate into current operations without major disruption, and have the potential to be cost effective. Their formal programmes include Far UVC at 222 nanometers, which has much higher exposure limits than conventional 254 nanometer UVC because of its shorter penetration depth. Conventional upper room GUV, which has been studied since the 1930s yet is still barely used. And glycol vapors such as propylene glycol and triethylene glycol, which have been shown to deactivate aerosolized pathogens and are already mass manufactured for industrial processes. These could be deployed during emergencies with emitters in homes or businesses to add air treatment capacity with relatively little cost or infrastructure.
