Gov. Hogan Says Johnson & Johnson COVID Vaccine, Made In Baltimore, Could Be ‘Major Breakthrough’ To Increase Supply

State officials expressed optimism Thursday about the Johnson & Johnson COVID-19 vaccine candidate that is being manufactured in Baltimore will get emergency use authorization from the U.S. Food and Drug Administration. During a news conference Thursday afternoon, Gov. Larry Hogan said federal officials told him it should be approved for use by the end of February. The company filed the emergency use authorization request in late January. Unlike other vaccines, Johnson & Johnson’s requires only a single dose and does not need to be kept at subzero temperatures.
