let's speak to professor michael genoveesa, president of the global policy institute. forjoining me, professor. a prime—time address such as this by a president can be a piece of history. did this one in your view count as history? i think we are going to have to go back to that interview and just a moment when we can, i think we are suffering from some little technical gremlins this morning. we will be back, hopefully, speaking to him about that historic first prime—time address by the president. let's move on, shall we, and talk about vaccine news. the oxford—astrazeneca vaccine has been suspended in three european countries, after reports that some people who've had the jab had developed blood clots. the european medicine agency has stressed the move was precautionary. norway and iceland announced their decisions after denmark stopped its rollout for two weeks. paul hawkins reports the ema's message is clear — there is no link between blood clots and the astrazeneca vaccine. the manufacturer says the drug's safety has been studied extensively in clinical trials. nev
