They're not just the parent company, J&J owns the vaccine. It's their property. The world knows the Johnson & Johnson brand. It's one of the top brands on the planet and has been for decades. Most of the world doesn't know Janssen. It's logical to call it the J&J vaccine accordingly, for marketing purposes it makes a lot more sense. If the Berkeley West Lab subsidiary of J&J produced the vaccine, nobody would call it the Berkeley West Lab vaccine.
