Joe Biden announces plans to help vaccinate world with 80 million US doses

President Joe Biden announced the US will share an additional 20 million doses of COVID-19 vaccines with the world in the coming six weeks. The doses would come from existing US production of Pfizer, Moderna or Johnson & Johnson vaccine stocks. It would mark the first time that US-controlled doses of vaccines authorized for use in the country will be shared overseas, as domestic demand for the shots has dropped significantly in recent weeks.
