Legionella
Desde su creación hasta la actualidad, La Unidad de Legionella tiene como principal función dar apoyo científico-técnico a la Administración General del Estado, a las Comunidades Autónomas y al Sistema Nacional de Salud en el campo de la prevención y control de la legionelosis, así como llevar a cabo investigaciones científicas en el contexto de la legionelosis. Además, la Unidad de Legionella también actúa como Laboratorio de Referencia de España frente al European Centre for Disease Prevention and Control (ECDC), siendo miembro de la red europea de vigilancia de la legionelosis, “European Legionnaires’ Disease Surveillance Network (ELDSNet). Finalmente, la unidad también realiza una actividad docente, participando en cursos de formación especializada, así como en Máster Universitarios.

Distinguished Scientist
ORCID code: 0000-0001-9400-427X
He holds a Bachelor's and a Ph.D. in Pharmacy from the Complutense University of Madrid, specializing in virology and molecular biology. His research has focused on the study of HIV and EBV. His doctoral thesis addressed the evolution of HIV-1 and the restoration of mutant HIV-1 reverse transcriptase function.
He completed a postdoctoral stay at Harvard University, investigating new viral interactions (2001–2003). At the University of Massachusetts, he explored CD8+ T lymphocyte responses in vertical HIV transmission (2003–2008).
In Spain, at the Hospital Clínico-IDIBAPS (Barcelona; 2008–2017) and the Carlos III Health Institute (Madrid; 2017–Present), he has led research on HIV-1 neutralizing antibodies and the design of preventive vaccines.He is currently co-leading, alongside Dr. Eloísa Yuste Herranz, the newly established Humoral Immunity and HIV Vaccines Unit.

Lorena Vigón Hernandez
Tenured Specialized Technician from OPIs
ORCID code: 0000-0002-6405-4054
Graduate in Health Biology and PhD in Health Sciences from the University of Alcalá de Henares. In 2016, she joined the CNM-ISCIII under a Youth Guarantee contract funded by the Community of Madrid, and in 2018 she was awarded a pFIS fellowship, which enabled her to remain at the same institution. Subsequently, in 2022, she was appointed as a Tenured Specialized Technical Staff of the Spanish Public Research Organizations (OPIs).
Her research has primarily focused on elucidating the mechanism of action of tyrosine kinase inhibitors in HIV-1 infection (PMID: 32828803; PMID: 34186065), as well as on the identification of biomarkers that could predict COVID-19 severity (PMID: 34616404; PMID: 34122423; PMID: 35960731).
She is currently a member of the recently established Humoral Immunity and HIV Vaccines Unit, led by Dr. Eloisa Yuste and Dr. Victor Sanchez-Merino.
Actualmente forma parte de la recientemente creada Unidad de Inmunidad Humoral y Vacunas frente al VIH, liderada por la Dra. Eloísa Yuste Herranz y el Dr. Víctor Sánchez Merino.
