Virologist, @johnshopkinssph.bsky.social Professor & @johnshopkinsmmi.bsky.social vice-chair @andrewpekosz.bsky.social PhD is co-chair -w/ @medschool.umaryland.edu's Justin Ortiz, MD- of @isrv.bsky.social Options XIII conference Aug 30 - Sept 2, 2026 Register and find out more here: isrv.global

Aging has effects that reshape the immune system in unique, sex-specific ways, but these differences are rarely taken into account (& most research is on males) An Essay @plosbiology.org argues that accounting for both sex and age is essential to advance personalized medicine plos.io/4wkqdgd 🧪

Such an honor to be involved with International Society for Respiratory Viruses and the planning for #OptionsXIII . If you are interested in influenza and other respiratory viruses, come to our meeting as registration is open: www.isrv.global/news/in-the-...

Added a word to my vocabulary today

The Department of Molecular Microbiology and Immunology is looking to grow! We opened a position for an assistant or associate professor, please distribute ! facultycareers-ohsu.icims.com/jobs/39006/a...

The Program for the Options for the Control of Influenza XIII meeting in Washington DC is coming together. Plenary and symposium talks are up and short presentations from submitted abstracts will be next. Time to register for the meeting!!! www.isrv.global/featured-eve...

Very sad to hear about the passing of Bernard Roizman. A real powerhouse in virology whose trainees are numerous and many have also had a profound impact on virology: www.annualreviews.org/content/jour...

The abstract submission deadline for the Options for the Control of Influenza XIII Conference, taking place August 30 – September 2, 2026 in Washington, DC at the Washington DC Convention Center has been extended to Friday, April 17, 2026. Come join us!!!! www.isrv.global/featured-eve...

mRNA could change how we prepare for flu season. JHSPH faculty Andy Pekosz says mRNA technology could shorten vaccine strain selection from 6–7 months to about 8 weeks. iqmediacorp.com/ExternalIfra...

Had a great session on virology and pathogenesis at the H5N1 preparedness forum here in downtown DC. @angierasmussen.bsky.social and I covered a wide range of topics...i had a blast and i think we were very informative as well (no slides!!!)

always a pleasure to be a guest on @publichealthpod.bsky.social , though its usually because some respiratory virus is running amok. this is episode 995 and i'm hoping i get a chance to be on #1000!

Happy Godzilla Day to all those who celebrate. Give a little love to the man-in-rubber-suit 50s-70s era Godzilla we all love - either openly or secretly! #GodzillaDay

The anti-vaccine movement has the same talking points now as it did in the 1800’s. It’s always been a rejection of science, scientists, and progress, with a soupçon of paranoia. Below is a slide for a talk I’m preparing that illustrates the identical strategies. I have more examples, too.

My department at Dartmouth Medical School is hiring a tenure-track Assistant Professor. We are looking broadly for a biochemist or cell biologist. Please share this add! apply.interfolio.com/171438 @dartmouthbcb.bsky.social @futurepislack.bsky.social

If you need more scary fun this weekend, the documentary “A Shot In The Arm” is free on PBS until 11/9. Lots of interviews with RFK Jr pre-HHS fame. Narrated by @neildegrassetyson.com from @scotthamkennedy.bsky.social. #Virosky #LoveVirology #TruthisScarierThanFiction www.pbs.org/show/shot-in...

A new preprint from the lab led by PhD student Elgin Akin is up at medRxiv: www.medrxiv.org/content/10.1... 1/6

Baked and decorated 100 cookies for our Fundamental Virology class! Hopefully everyone will do well on their final exam tomorrow, but if not, a cookie can’t hurt, right? @andrewpekosz.bsky.social

Last class in our Fundamental Virology class. Record number of students this term @karidebbink.bsky.social @johnshopkinsmmi.bsky.social @johnshopkinssph.bsky.social

I do biomedical research to help people. When people come in this space making things up, it makes it harder for people not in the field to trust the extensive studies that we do and distinguish fact from fiction. Baseless claims reduce future cures. Willful ignorance drives us backwards.

PhD Candidate & @andrewpekosz.bsky.social Lab member Camille Wouters defends her PhD thesis tomorrow. Good Luck, Camille! 📆 Friday, Sept. 26, 2025 ⏰ 10:00 - 11:00 a.m. 📍 @johnshopkinssph.bsky.social 🏢 W2030

Found this book in my department mailbox yesterday. No envelope, no shipping information, no note and I was the only person to receive this "gift". Clearly, someone needs to come to my lecture on the origin and evolution of the COVID-19 pandemic to get educated on the facts.

“It’s not so much that the virus has become less dangerous, it’s that we have immunity, so we fight off the virus more efficiently than we did early in the pandemic,” said @johnshopkinssph.bsky.social @jhu.edu Professor and Virologist @andrewpekosz.bsky.social www.iflscience.com/rfk-jr-pulls...

Requiring grant review by political appointees will continue to delay and disrupt critical research and interferes with scientists’ ability to help protect the nation’s health and security. Read our statement: asm.org/press-releas...

Congratulations to Jerome Edwards on defending his PhD thesis on mechanisms driving the attenuation of Live attenuated measles vaccine virus replication. Jerome did great things and is yet another example of Diane Griffin's mentoring. @johnshopkinsmmi.bsky.social @johnshopkinssph.bsky.social

📢New job posting!📢 Are you excited by the idea of building global infrastructure to make pathogen sequencing more accessible, interpretable, and equitable? 🧑🏻‍💻🧬 My group at @swisstph.ch has an opening working with ARTIC2, @pathoplexus.org, & Loculus - read on! 1/5

Our two summer students wrapped up their stays in the laboratory with posters on the influenza viruses that circulated this past year. One preprint is up and another is coming. lots of thanks to @ceirrnetwork.bsky.social and @johnshopkinsmmi.bsky.social for support and collaborations!

A new preprint from the lab describing an influenza B virus that emerged late in the 2024-25 season that underwent both reassortment and antigenic drift with @eakin.bsky.social leading my team in this collaboration with Heba Mostafa at Johns Hopkins Medicine ‪ www.biorxiv.org/content/10.1...

Some really interesting work coming from the late Diane Griffin’s laboratory driven by @johnshopkinsmmi.bsky.social PhD student Jerome Edwards that looks at the mechanisms behind the attenuation of the live, attenuated measles vaccine or LAMV. www.biorxiv.org/content/10.1...

End of our COVID-19 Era. We are leaving the laboratory space that was established in February, 2020 to increase our capacity to do COVID-19 research.

"Population immunity, either from vaccination or previous infection, also tends to wane by the summer," @johnshopkinssph.bsky.social Professor & Virologist @andrewpekosz.bsky.social, tells TODAY.com. #COVID #vaccination #PopulationImmunity #NB.1.8.1 #variant www.today.com/health/coron...

There is still time to apply; join our team to work on influenza virus replication mechanisms!

Lol just tried to talk to a virologist about artistic license in #sciart and she was not having it 😂

Anyone going to Artscape in Baltimore this weekend who is interested in science art needs to find their way to the @artologica.net booth. i already see things i want...

The first manuscript by my lab has been published🥳🎉 We investigated disease progression in B6 mice inoculated with bovine H5N1 or VN1203 via aerosols. Interestingly, although virus replication in the lung was similar, we observed drastic differences in neuroinvasion and pathology. rdcu.be/enhQU

“Because there are so many people who have been #vaccinated and #infected, there is a high amount of #immunity in the population,” said @johnshopkinssph.bsky.social @andrewpekosz.bsky.social “I think we’re also seeing that as a way to dampen the spread of the virus.” www.wsj.com/health/healt...

Worked on a manuscript with @meghandavisdvm.bsky.social this morning, and now I see her receive the prestigious Stebbins award for public health teaching and contributions @johnshopkinssph.bsky.social . Congratulations!!!

Always a thrill to see the smiling faces of our @johnshopkinssph.bsky.social graduates...even on a rainy, chilly day. 61 countries represented and over 1200 different degrees being conferred.

We got a chance to celebrate our gradating ScM students from @JohnsHopkinsMMI this past week. Got to work with these 5 fantastic students and two more who I didn't get pics with.

Since i rarely post pics of myself, most of you don't know that i've grown out my beard recently. Seeing an article linking beards with toilets made me pause, but then my colleague Kim Davis' comments made me feel slightly better... www.washingtonpost.com/wellness/202...

lots of reasons why you (or your pets) shouldn't drink raw milk...pretty much no reason why you should. great article from @asm.org summarizing what we know.
