Dr. Fauci says Johnson & Johnson vaccine pause “isn’t a cancellation” From CNN's Aditi Sangal and CNN Health's Naomi Thomas Vials of the Johnson & Johnson Covid-19 vaccine in San Rafael, California, on March 25. David Paul Morris/Bloomberg/Getty Images Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said that the pause on the Johnson & Johnson vaccine is only a pause – not a cancellation – and he doubts it will extend for weeks to months.
