Simian adenovirus-vectored vaccines

Simian adenovirus-vectored vaccines use harmless viruses from monkeys (simian adenoviruses) as delivery vehicles to carry genetic instructions for a disease-causing virus, such as COVID-19, into human cells. Once inside, these cells produce a protein from the target virus, triggering the immune system to recognize and fight the actual pathogen if encountered later. This approach helps generate immunity without causing illness. These vaccines are appreciated for their stability, safety, and ability to produce a strong immune response, making them a promising tool in modern vaccine development.
