The BBC reports on an experimental COVID-19 vaccine that uses adenoviruses to deliver coronavirus genetic material, prompting the body to produce spike proteins and train the immune system. The vaccine aims to prepare the immune system to recognize and combat COVID-19. At the time of reporting, two volunteers had received the vaccine, with potential side effects including headache, fever, and muscle pain.
