“This feels just like the early days of the HIV crisis. People are dying, you’re not hearing about it. We need a group like ACT UP to bring this to the public. We’re not going to get phage therapy until people start demanding we have it.”

Listen to the full conversation with patient advocate Chris Shaffer on our latest Podovirus podcast episode.

What’s New

Alexander Perfilyev (University of Copenhagen) and colleagues published a new preprint on discovering lytic phages in bacterial genomes, showing over 100,000 complete lytic phage genomes in bacterial assemblies, challenging assumptions and revealing a vast untapped reservoir of potentially therapeutic phages.

Research paperGenomicsPhage isolation

Fernando Gordillo Altamirano (Monash University) and colleagues published a new paper on phage therapy failure mechanisms, showing pre-existing anti-prophage antibodies and bacterial heteroresistance contributed to treatment failure in a patient with chronic Bordetella bronchialis infection.

Phage therapyPhage-immune interactions

Sarah Macdowell (The Ohio State University) and colleagues published a new paper on meropenem interactions with P. aeruginosa phages. They found that phages PEV2 and ΦKMV reduce bacterial burden in vitro and ex vivo, with enhanced efficacy when combined with meropenem.

Research paperPhage-antibiotic synergy

Alexandre Boulay (Ghent University) and colleagues published a new paper on segmentation of phage endolysin domains, showing SPAED achieves higher accuracy than existing tools by using AlphaFold’s predicted aligned error matrix for hierarchical clustering of protein residues.

Research paperEndolysinsBioinformatics tools

Seyoung Ko (Ulsan National Institute of Science and Technology, Korea) and colleagues published a new paper on deep learning-guided structural analysis of phage KPP105. Structural similarity analysis showed how its receptor binding protein facilitates interactions with host receptors and distinguishes between strains.

Phage-host interactions, Phage Therapy, Phage manufacturing, Phage delivery

I’m a co-founder of Phage Directory and have a PhD in Microbiology from the University of Alberta (I studied Campylobacter phage biology). For Phage Directory, I help physicians find phages for their patients, and I’m always trying to find new ways to help the phage field grow (especially through connecting people and highlighting awesome stuff I see happening in the field).

I spent 2022-2024 as a postdoc in Jon Iredell’s group at Westmead Institute for Medical Research in Sydney, Australia, helping get Phage Australia off the ground. I helped set up workflows for phage sourcing, biobanking, diagnostics, production, purification and QC of therapeutic phage batches, and helped build data collection systems to track everything we did. We treated more than a dozen patients in our first year, and I’m so proud of that!

As of 2024, I joined the Bollyky lab at Stanford University as a Staff Scientist, where I’m focused on phage engineering and delivery (to both microbial and human cells) and hydrogel-embedded phage cocktail development for wounds!

“This feels just like the early days of the HIV crisis. People are dying, you’re not hearing about it. We need a group like ACT UP to bring this to the public. We’re not going to get phage therapy until people start demanding we have it.”

This week on the Podovirus Podcast, we talk to phage therapy patient advocate Chris Shaffer about how he fought for access to phage therapy to save his own life, and how it’s led him to advocate on behalf of other patients being told there’s “nothing left” for their infections.

He draws parallels between phage advocacy and 1980s AIDS activism, while sharing his successful treatment journey to Tbilisi, Georgia for phage therapy. He shares his vision for a patient-centered future where anyone, not just the well-connected or the lucky, can access phage therapy if it could help them.

A taste of what we discussed:

  • First: Chris’ own clinical success: After two years of consistently high bacterial counts (>100,000 CFU) while on antibiotics, Chris saw his E. coli with ESBL infection completely eliminated after just three 20-day rounds of phage therapy at the Eliava in Tbilisi —with no side effects and sustained clearance 20 months later.
  • Information barriers for patients: As Chris sees it, phage therapy still faces a three-part challenge: awareness (patients don’t hear about it), trust (patients aren’t sure it’s legitimate), and access (even informed patients struggle to find treatment)
  • Medical education gap: An infectious disease intern Chris met from a prestigious US institution had never heard of phage therapy despite just completing medical training—underscoring the systemic nature of awareness barriers.
  • Patient-to-patient networks: Before committing to treatment in Georgia, Chris needed to connect with another phage therapy patient (Pranav Johri) who had been through the process—highlighting how patients might solve the trust barrier for each other.
  • Potential fundraising model: We discuss how small-scale patient fundraising networks could provide the modest funding needed for academic labs to prepare phage treatments for compassionate use cases, similar to Diane Shader-Smith’s fundraising and advocacy work on behalf of her daughter Mallory.

A few snippets from the episode…

On the communication challenge:

“Obstacle number one, you will not hear about phage therapy. It doesn’t matter what doctor you’re seeing in the United States, you’re not going to hear the word phage therapy… If you are able to get a compassionate use waiver to try phage therapy in the United States, the next obstacle is finding the phage. I didn’t know anybody. Who am I going to turn to to find a phage that’s going to work for my infection?”

On his own infection recovery:

“I woke up in the morning on the third round, the 12th day, and I walked into the bathroom to do my morning routine… I was looking at my weathered face and I said to myself, ‘It’s gone. It’s literally gone.’ I could tell. I didn’t need a test… I sat down on the edge of the tub and I started to cry. I literally did because I knew it was gone. And, sure enough, I finished that last round of phage. Two weeks later, I had a test. No sign whatsoever of E. coli, and it has remained that way ever since.”

On his unique advocacy position:

“I sit in a very unique place. I’m 67 years old, I’m retired, I have a pension. I don’t need any money. I don’t have to look for a job. I’m not doing this because I think I’m going to get some kind of job out of it… I can say exactly what I want to say. And not everybody has that freedom… I can’t wait until the day where they say Shaffer, nobody needs you anymore because phage is out there, everybody knows about it and everybody’s using it.”

What’s next for phage advocacy?

Chris envisions several pathways forward: establishing patient-funded compassionate use centers, better educating physicians starting in medical school, and creating clearer communication about the FDA’s stance on phage safety. He’s exploring the possibility of a Palm Springs treatment center that could serve as a model for patient access, and suggests developing small-scale fundraising networks to support research labs that make phage preparations for compassionate use. His approach balances respecting the scientific process while arguing that existing regulatory pathways could be better utilized for greater access.

We are so grateful to you Chris, for sharing your story with us here!
