Johnson & Johnson plans to start human testing of its experimental coronavirus vaccine by September and make it ready for emergency use in early 2021, the drugmaker said on Monday.
J&J also committed more than $1 billion of investment along with US agency Biomedical Advanced Research and Development Authority (BARDA) to co-fund vaccine research, expanding a previous collaboration.
Global efforts are underway to develop a vaccine for the virus that has killed over 34,000 worldwide, but experts have cautioned it could take over a year to have a vaccine ready.
A patient was dosed with Moderna Inc's vaccine in an early-stage trial earlier this month, making it the front-runner in the race to develop a viable vaccine.
J&J said in January it had begun working on a possible vaccine for the coronavirus, using the same technologies used to make its experimental Ebola vaccine.
