Britain has bought 100 million doses of the vaccine and plans to begin injections within days. Hundreds of thousands of people in the UK have already received a different vaccine, made by US drugmaker Pfizer and German firm BioNTech. A separate study testing the AstraZeneca vaccine in the US also is underway. The vaccine will now 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.
