Pfizer executives said on Tuesday that they could still deliver Covid-19 vaccine in the year 2020. Pfizer chief executive Albert Bourla said the drug giant could supply some 40 million doses in the United States in 2020 if clinical testing proceeds as expected and regulators approve a vaccine. “If all goes well, we will be ready to distribute an initial number of doses,” said Bourla, who pointed to a US government contract for Pfizer to supply 40 million doses by the end of this year and 100 million doses by March 2021.
