President Biden to announce his administration has secured 200 million additional vaccine doses promised last month

President Biden is expected to announce Thursday afternoon that his administration has secured deals for another 200 million doses of coronavirus vaccine as promised last month, according to three people familiar with the matter who were not authorized to discuss it. The president is scheduled to tour the National Institutes of Health on Thursday afternoon and deliver remarks to staff there. He had indicated last month his administration was seeking another 200 million doses of the two vaccines authorized for emergency use in the United States to be available this summer — 100 million of the product developed by Pfizer and German company BioNTech, and 100 million of the product developed by Moderna.
