Ofer Levy MD, Ph.D., brings precision medicine principles to vaccine research by building collaborative, multi-disciplinary international teams that create innovative vaccines tailored to the specific needs of vulnerable populations. His team has developed blood-based systems that model human immunity outside the body leading to discovery that the human immune system changes markedly with age, and highlighting the need to develop vaccines optimized to protect specific populations at high risk of infection such as the very young or older adults. Dr. Levy is Director of the Precision Vaccines Program, physician in the Division of Infectious Diseases at Boston Children’s Hospital, and Professor at Harvard Medical School. He leads NIH-funded projects that define molecular mechanisms of vaccine protection in infants and discover adjuvants, small molecules that boost immune responses enabling creation of age-specific vaccines. His team is working on adjuvanted vaccines to protect vs COVID-19, influenza and HIV, and opioid overdose. He has published >150 articles, serves on the FDA vaccine advisory panel, and frequently appears in media including CNN, FOX, and TED.
