As vaccines by Moderna and Pfizer/BioNTech continue to be administered across the U.S., fellow pharmaceutical giant Johnson & Johnson is close to distributing their own COVID-19 vaccine. Johnson & Johnson board member and former Food and Drug Administration commissioner Dr. Mark McClellan told CNBC that “if the clinical trial works out,” the company could have “perhaps enough vaccines for 100 million Americans by spring, by this April or so.” During remarks at the White House Thursday, Dr. Anthony Fauci, who is overseeing the Biden administration’s COVID-19 response, said Johnson & Johnson would have enough data on its vaccine to begin analysis within a week or two, after which the FDA would have to approve the data and authorize the vaccine’s distribution. Unlike current vaccines, Johnson & Johnson’s requires only one injected dose, not two, and reportedly can be stored at standard refrigerator temperatures for up to three months, longer at colder temperatures.
