LONDON, Feb 25 (Reuters) - AstraZeneca's Chief
Executive Pascal Soriot said on Thursday he is "confident"
yields in its COVID-19 vaccine will increase in the second
quarter, as the company aims to boost European Union supplies
after big cuts in the first three months of the year.
Soriot said the company aims to deliver doses from its
international network, including the United States, so that it
can meet volumes originally agreed in its deal with the European
Union signed last year.
Lower-than-expected yields - the amount of vaccine that can
be made from base ingredients - at its factories hurt output in
the first three months, he said.
