From what I've read, Johnson & Johnson started testing when the new covid variants (Africa, Brazil) came out (vs the two others) and it was less effective in prevention, but prevents hospitalization, according to their trials. The J&J vaccine recently showed up at universities and some drug stores here. Also, they are doing a study of giving a second dose about 2+ months apart to see if a booster helps.
