Dr. Ofer Levy, MD PhD

Thank you to the incredible panel of researchers who presented at the Immune Development in Early Life Hot Topic Symposium this weekend at @PASMeeting #PAS2026. Their work highlights just how critical and dynamic early immune development is in pediatrics. By continuing to study this window, we can help improve outcomes, better understand how to shape immune responses, and drive new discoveries. We look forward to continuing the conversation at #PAS2027 in Minneapolis, MN, and sharing our next wave of findings in this exciting field.

Tomorrow, Sunday April 25th, @levy_o will chair the @PASMeeting Hot Topic Symposium: “Immune Development in Early Life (IDEAL) shapes vaccine response, respiratory infectious disease and asthma”. The session will occur from 2:30-4:00 pm in 213 West in the Thomas M. Menino Convention & Exhibition Center. The symposium will feature presentations from leading researchers in the field followed by a Q&A session. We hope you will join us in attending this special session! #PAS2026 #ImmuneDevelopment #IDEAL #PrecVaccinesNetwork

Members of the @PrecVaccines team and Precision Vaccines Network will be attending and presenting at @PASMeeting this weekend! If you are attending, please feel free to stop by our sessions to hear updates on our research, insights, and discoveries! @levy_o @JoannDArce @BiotechByron @KingaSmolen @elissa_weitzman #PASBoston #PAS2026 #PAS #Immunology #Vaccines #PrecisionVaccinesNetwork

Many thanks to Dr. Daphna Barbeau for interviewing me re @PrecVaccines on the@nicupodcast at #PAS2026

Loved having all our #PAS2026 social media ambassadors together this morning! 🙌 Thanks for bringing the energy and for all the amazing work you do, we appreciate you!

Dr. Mercy Prabhudas, Program Officer at the @NIH, National Institute of Allergy and Infectious Diseases (NIAID), visited us today from Maryland. It was our pleasure to host her at our @PrecVaccines space. @NIH_Innovates Pictured: @levy_o, @AmodioDonato, Paolo Palma, @D_J_Martino, Kinga Smolen PhD, Kerry McEnaney, Marco Sanna, Asimenia Angelidou, Joann Diray Arce, Mercy Prabhudas, Annmarie Hoch, Utsa Bhaduri

We are excited to announce we've officially begun dosing patients in our Phase 1/2 clinical trial! Thank you, @RobertLangreth and @Bloomberg, for continuing to support our mission. bloomberg.com/news/articles/…

New publication out in @JACIGlobal. In this #NIH supported randomized study, our team examined how two newborn vaccines given in many parts of the world via the Essential Program on Immunization (EPI), Hepatitis B vaccine (#HBV) and bacille Calmette-Guérin (#BCG), interact when given in the first week of life. The trial was conducted with partners in The Gambia and Papua New Guinea, bringing together clinical sites and research teams across Africa, Oceania, Europe, North America, and Australia. What we found: Our results support the immunogenicity of HBV in newborns and examine how the timing of HBV and BCG vaccination may influence early immune responses. These findings help clarify how vaccine scheduling in the first days of life can shape protection against hepatitis B, an important step towards precision vaccines for the very young. This work reflects a global collaboration spanning institutions and field sites including: • @mrcunitgambia • @pngimr • @BostonChildrens @harvardmed • @broadinstitute and • partners across Canada, Australia, the UK, Belgium, and Germany. We are grateful to the families who participated, the clinical teams in The Gambia and Papua New Guinea, and the many collaborators in the @EPICVaccines consortium who made this study possible. Importantly, this work evaluates licensed vaccines already used worldwide and focuses on understanding how newborn immune responses develop, not on experimental vaccine policies. 📄Read the article here: bit.ly/4c1cu4F #Vaccines #NeonatalImmunology #HepB #BCG #GlobalHealth #PrecisionVaccines @LSHTM_Vaccines @PrecVaccines @JoannDArce, Caitlin Syphurs, Tobias Kollmann, @levy_o, @PeterCRichmond , Anita van den Biggelaar, Beate Kampmann, @bukkyidoko, Al Ozonoff

Our program is excited to announce the AIDD lab’s latest publication in @NatureComms: Brandon Lee, Danica Dong, Etsuro Nanishi, @David_J_Dowling, @levy_o, and more report on the discovery and development of PVP-057, the first fully synthetic small molecule that selectively activates human and mouse TLR3. In preclinical studies, intradermal or intramuscular administration of PVP-057 induces robust humoral and cellular immune responses.

Our recent #IMPACC research helps explain why people experience #Covid_19 so differently. Read the entire article @PNASNews here: pubmed.ncbi.nlm.nih.gov/41410771/ We discovered that a combination of genetic background and metabolic status is associated with disease severity and underscores the need to consider various aspects of the patient's health status when assessing risk and treatment strategy. Our research found that a common gene variant, found in about 10% of the general population - MTHFR C677T - is associated with COVID-19 severity and long COVID, but only in patients that carry the variant while also manifest a specific metabolic profile, that can be measured in the patients' blood. This genetic–metabolic link points toward more personalized ways to understand and manage risk, and strategize treatment.
