📍BREAKING—At last—new data on 2-doses of Johnson & Johnson's #vaccine (doses 56 days apart) is 94% effective against symptomatic #COVID19, thus comparable to Moderna/Pfizer. And 100% effective against severe COVID. Booster for 1 dose works well too. 🧵https://t.co/3nPkodOjuG pic.twitter.com/DizjWt9NYX
