Getting the shingles vaccine didn’t make people go to the doctor more for other things or change how often they were diagnosed with common long-term illnesses like diabetes or high blood pressure—so if people who got the vaccine had less dementia, it’s probably because the vaccine itself helped, not because they got better overall care.
