We are excited to announce that a new grant with Dr. Caceres as Co-I totaling $2,000,000 has been awarded through the USDA APHIS HPAI Poultry Innovation Grand Challenge.
The project, titled “Protection and Immunity Induced by Avian Influenza Nano Vaccine (AI-nanovax) in Chickens,” aims to advance poultry health through cutting-edge vaccine technology. The research will be focusing on generating a DIVA-compliant, nanoparticle-based vaccine platform incorporating multiple influenza antigens. It will characterize vaccine safety and immune response breadth in chickens.
This initiative represents a significant step forward in protecting poultry from avian influenza, supporting both animal health and the agricultural industry.

A proposal submitted to the National Pork Board (NPB) was recently funded. This project aims to develop a reverse genetics system for Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) to create a RG-based, recombinant-impaired, modified live vaccine candidate. This project will deliver a powerful tool that will significantly aid in the better understanding of the PRRSV biology.
Co-Investigators:
Michael Zeller (VDPAM-CVM), Phillip Gauger (VDPAM-CVM), Jianqian Zhang (VDPAM-CVM), Alexa Buckley (ARS-USDA), and Jayne Wiarda (ARS-USDA).

Dr. Caceres is visiting Federal University of Mato Grosso do Sul (UFMS) in Brazil, where Dr. Leila Ullmann, head of the laboratory of veterinary virology, is hosting him. The purpose is to develop new connections and collaborations in virology. Dr. Caceres will give several lectures and seminars and interact 1-on-1 with students at the faculty. We thank Dr. Ullmann for all the support, and the LAC Connections Fellowships Application from the National Academy of Sciences, which provided the resources for this trip.

On August 7th, Tommy presented at the Veterinary Scholars Symposium in Spokane, WA. He presented his summer research titled “Host range and binding profiles of influenza A(H5N1) in livestock species” and answered questions from students and faculty. The Caceres lab congratulates Tommy on sharing his work at the symposium. We thank the Iowa Livestock Health Advisory Council (ILHAC) for the support!

We are excited to announce that the Cáceres lab has been awarded a grant that will advance our research on influenza. The primary goal is to examine the role of influenza A viral factors, in the viral replication and the host response using a three-dimensional organotypic model of human tracheal and bronchial epithelial tissue combined with single-cell sequencing techniques.

A team led by Dr. Carnaccini and Dr. Caceres, in collaboration with CSIRO, Australia, was recently awarded a project to address the growing threat of highly pathogenic avian influenza (HPAI). The research aims to uncover the genetic factors that make some birds more resistant to infection. The project will focus on the H5Nx HPAIV strain, which has had devastating effects on poultry, wildlife, and food supply chains. Current control methods—such as strict biosecurity and eradication programs—have proven insufficient, and trade restrictions prevent the use of vaccines. With recent advances in precision breeding, the team sees new opportunities to develop poultry that are genetically resistant to the virus, but doing so requires a deeper understanding of the host’s genetic response to infection.
