| A century-old TB shot could protect against Covid-19, Russia sells its vaccine to more than 10 countries, and the common cold strains testing and supplies. Here’s what you should know:Headlines A century-old TB vaccine shows some promise for fending off Covid-19 Research has found that an old tuberculosis vaccine for newborns protected people over 65 against viral respiratory infections. Some scientists say this suggests that the shot creates a “trained” innate immune response that rewires the immune system to ward off multiple diseases. Now there’s hope that this vaccine could also protect against Covid-19, and there are at least 20 randomized clinical trials underway. Russia sells its controversial Covid-19 vaccine to more than 10 countries Russia has struck deals to sell its Covid-19 vaccine to more than 10 countries including Brazil, Saudi Arabia, and India, and is in talks with roughly 10 other countries. The shot was approved by Russian authorities in August after small-scale tests on just 76 volunteers had been completed. It began trials on 40,000 volunteers late last month. It will be manufactured and distributed as soon as November, though it will require local regulatory approval before distribution. |
