Can I use my valid B1/B2 visa for personal vacation, if it was originally applied and used once before for business meeting?

I have valid B1/B2 visa till 2022. The visa was originally applied for business travel and I had already travel once after that. Now I want to travel for family vacation. Is the current visa having “R-B1/B2” good enough or I have to apply for B2 visa again?
