Yes, you have more than enough antibody now. Level above 10 is considered protected. However, because you did not mount antibody well after the first course I will suggest to have the level checked again next June 2022, especially you are at risk for hep B exposure, e.g. health care worker or dialysis patient, etc. If level is still above 10 next June, you will no longer need booster.
