It seems like you are implying that the pause was lifted because they found nothing. That's not quite right. J&J vaccine killed 9 people, and the FDA issued restrictions on who could get it, limitations on who should get it, and warnings about the side effects.
Your source doesn't mention the nine deaths or the blood clotting side effect. It doesn't convey that there were legitimate, validated reasons for the pause and downgrade. "Rare reports" and "Nine Deaths" reads differently.
