At least a dozen countries including Germany, France, Italy and Spain have now temporarily suspended their use of AstraZeneca's coronavirus vaccine after reports last week that some people in Denmark and Norway who got a dose developed blood clots, even though there's no evidence that the shot was responsible. The European Medicines Agency and the World Health Organization say the data available don't suggest the vaccine caused the clots and that people should continue to be immunized. Here's a look at what we know — and what we don't.(AP Photo/Christophe Ena, File)
