Adenoviral vector vaccines

Adenoviral vector vaccines use a harmless version of a common virus, called an adenovirus, to deliver genetic material from a pathogen, like the virus that causes COVID-19. This genetic material instructs our cells to produce a harmless piece of the pathogen, often a protein, which triggers an immune response. This prepares the immune system to recognize and fight the actual virus if encountered in the future. These vaccines are designed to be effective and prompt a strong immune response, helping protect against infectious diseases.
