Comparing three Covid-19 vaccines: Pfizer, Moderna, J&J

• Developed by J&J’s vaccines division, Janssen Pharmaceuticals, it was shown to be 66% protective against moderate to severe Covid infection in a multi-country study. Importantly, it was 85% effective in protecting against severe disease. And there were no hospitalizations or deaths among people in the vaccine arm of a large clinical trial. The J&J results are from an interim analysis of a study of 44,325 volunteers in which 468 symptomatic cases of Covid-19 occurred. (Paragraph 14)
