CHICAGO (Reuters) - Johnson & Johnson is on track to roll out its single-shot coronavirus vaccine in March, and expects to have clear data on how effective it is by the end of this month or early February, the U.S. healthcare company's chief scientific officer said.

Dr. Paul Stoffels in an interview on Tuesday also said J&J expects to meet its stated target of delivering 1 billion doses of its vaccine by the end of this year as the company ramps up production.
