AstraZeneca: Vaccine Is 79% Effective In U.S. Trials

AstraZeneca's US trial shows its COVID-19 vaccine is 79% effective in preventing symptomatic disease. The vaccine is already approved in many countries outside the US, and the company plans to seek emergency authorization in the US soon. Despite some European countries pausing its use due to blood clot concerns, health officials found no link between the vaccine and these incidents, declaring it safe. However, a poll indicates that public perception in Europe has been negatively affected, with many viewing the vaccine as unsafe.
