viral vectors

Viral vectors are tools that use modified viruses to deliver genetic material into a person’s cells. Scientists remove the virus's harmful parts and replace them with useful genes. When the virus infects cells, it delivers this new genetic material, which can stimulate an immune response or correct genetic problems. Viral vectors are commonly used in gene therapy and vaccine development because they can efficiently target specific cells and deliver genes safely. Think of them as biological delivery vehicles, designed to transport therapeutic cargo without causing disease.
