Officials from Merck & Co Inc, Moderna, Pfizer Inc, AstraZeneca and Johnson & Johnson will testify on July 21, the House Committee of Energy and Commerce said on Thursday.
"This hearing will provide an opportunity for both Congress and the American people to hear directly from some of the manufacturers currently developing potential COVID-19 vaccines," the committee said.
The five companies, alongside several others, are racing to develop vaccines for COVID-19, caused by the novel coronavirus, and the United States has poured billions in funding some of them to secure access to vaccines should they work.
At the hearing, the companies are also expected to share information about their preparations to manufacture and distribute an eventual vaccine.
None of the five companies immediately responded to Reuters' request for a comment.
