Pfizer shares fell Thursday after a report said the U.S. drugmaker expects to ship half of the Covid-19 vaccines it originally planned for this year due to supply-chain problems.

The Wall Street Journal, citing a person directly involved in the development, said some early batches of the raw materials needed for the vaccine failed to meet standards. Pfizer now plans to ship 50 million vaccines by the end of the year, down from the original 100 million it had hoped to send out, according to the Journal.
