Dr Ricardo Rosales | From Smallpox to Cancer: How Vaccinia Viruses Are Revolutionizing Vaccine Development

May 19, 2025 | biology, health and medicine

About this episode

Vaccines have long been celebrated for their ability to prevent diseases, but some are now being developed to treat existing conditions, such as cancer and viral infections. One promising approach is the use of vaccinia viruses, which were historically used to eradicate smallpox. These vaccines prompt an immune response that can eliminate threats, including cancer cells and cells infected by viruses.

Dr. Ricardo Rosales and his colleagues at VIROLAB are at the forefront of this field, leading innovative research into two vaccinia viruses: MVA and GAB-1.
