It is composed of two adenoviruses, Ad26 and Ad5, modified to carry the gene for the spike protein of SARS-CoV-2, the virus that causes COVID-19. The vaccine has been shown to be highly effective in clinical trials, with an overall efficacy rate of over 90%, and has been approved for emergency use in dozens of countries around the world.
