The government is in talks with U.S. health care conglomerate Johnson & Johnson about securing allocations of its potential COVID-19 vaccine as the company prepares to kick off human trials, the firm's Chief Financial Officer Joseph Wolk said in an interview.

More than a hundred vaccines are under development to try and stop the COVID-19 pandemic, and drugmakers including J&J are working to ramp up their supplies of their vaccines in the face of unprecedented demand.

J&J has already agreed to prioritize an allocation to the United States as part of its funding agreement with the U.S. government's Biomedical Advanced Research and Development Authority (BARDA), Wolk said.
