AstraZeneca releases US trial data for coronavirus vaccine
AstraZeneca announced that its coronavirus vaccine is 79% effective in preventing symptomatic cases and 100% effective against severe cases and hospitalization based on late-stage US clinical trials. The study also found no increased risk of blood clotting (following concerns in several European countries earlier this month). The company plans to request emergency use authorization from the FDA in the coming weeks.
