(NBCNC) — Johnson & Johnson announced its COVID-19 vaccine candidate has begun the final stage of clinical trials in the U.S.
The company aims to enroll up to 60,000 adults in eight countries, including the U.S.
Unlike other vaccines, which will require two doses one month apart, the Johnson & Johnson vaccine can be given in just one dose.
If the vaccine is proven to be safe and effective, the company expects the first batches to be available for emergency use authorization in early 2021.
This marks the fourth vaccine to enter late-stage trials in the U.S.
Johnson & Johnson says it will take at least two months to see the initial results from the trial.
