Johnson & Johnson is planning to have enough COVID-19 vaccines for 100 million Americans by April if its clinical trial works out.

Right now, Johnson & Johnson is conducting a large-scale trial to make sure the vaccine is safe and effective.

Dr. Anthony Fauci says the company is expected to seek emergency use authorization from the FDA in the next week or two.

Unlike the Pfizer and Moderna vaccines, Johnson & Johnson's vaccine is a single shot and doesn't need to be stored as cold.
