Russian-developed vaccine unlikely to be available in US
Russian officials say early analysis shows a coronavirus developed there is 92% effective.
tonight another promising vaccine announcement. But can it be trusted Russia naming it Sputnik after the Soviet era satellite, implying in a promotional video? It will save the world in this laboratory, especially if we purify proteins on tonight. Russian scientists in this lab say interim data shows 92% effectiveness, though that's with 16,000 volunteers, less than the 43,000 for America's Pfizer vaccine. We traveled to Moscow, where the lab's director told me two doses could give two years immunity longer than fighter. Two years. Russia is already vaccinating frontline workers like doctors is a good problem. It's very important program, important, important for people and important for Russia. Know it but for people. But leading scientists worry the preliminary results are being rushed out on not independently reviewed. That's very important that the World Health Organization gives it a stamp of approval before they start exporting it all over the world. Unlike fighters version, Russia's vaccine may not need to be kept frozen, aiding distribution, but it's unlikely ever to be approved in the U. S. Kier Simmons, NBC News, London
