Britain on Wednesday became the first country to authorize an easy-to-handle COVID-19 vaccine whose developers hope it will become the "vaccine for the world." Britain has bought 100 million doses of the vaccine. A separate study testing the AstraZeneca vaccine in the United States also is underway. The vaccine will become the second COVID-19 vaccine in use in Britain. In June, the pharmaceutical company announced that the Serum Institute would produce 400 million doses by the end of 2020, but as of early December, only about 50 million doses had been manufactured after production was halted several times.
