The vaccine is currently undergoing final-stage clinical trials involving 60,000 participants at more than 200 locations in the US and other countries. Results are expected in late January.
J&J's Stoffels said the firm's Phase III trials -- which had to be interrupted briefly when one subject fell ill -- are now "in full swing", adding: "We target for results the month of January for efficacy and safety."
AstraZeneca, a leading rival in the world scramble for a coronavirus vaccine, has also pledged to sell its candidate at cost -- around 2.50 euros ($2.80) per dose -- while Pfizer of the United States has targeted a top price of around $40.
J&J had said in September that it hoped to win emergency authorisation to market its vaccine early next year.
Unlike some rival vaccines that require storage at extremely low temperatures, J&J's can be kept at 2.0 degrees Centigrade (35.6 Fahrenheit).
Speaking at the same conference, organised by the International Federation of Pharmaceutical Manufacturers and Associations (IFPMA), the head of Swiss lab Roche, Severin Schwan, said the at-cost model for vaccines could stymie innovation in the future.
"It's a good model during a crisis, but I don't think it can be a standard for sustainable innovation in the long run," said Schwan, the IFPMA vice president.
