Should I Get the Measles Vaccine at 67?

I'm 67 and wondering if I should get the measles vaccine or just check my immunity with a blood test. I've heard older adults might already be immune, but I'm not sure if that's true for everyone. Has anyone else my age gone through this? Would love to hear what others decided or what their doctors recommended! #HealthQuestions #Vaccines #SeniorCare #Health #Diet
