Scientists have found in a new study that the shingles vaccine may not only protect against viral infections but could also help slow biological ageing in older adults.
Researchers from the University of Southern California said the vaccine — routinely administered to elderly people — may have benefits beyond protection from shingles.
The study, conducted on more than 3,800 individuals, revealed that people who received the vaccine showed significantly lower signs of biological ageing and inflammation compared to those who were not vaccinated.
Lead author Jung-Ki Kim explained that by reducing underlying inflammation, the vaccine may help prevent the reactivation of the virus responsible for shingles. This process could contribute to healthier ageing.
According to the researchers, the findings support recent studies that have identified a link between vaccines commonly given to older adults — such as shingles and influenza vaccines — and a reduced risk of dementia and other neurodegenerative diseases.
The study highlights the growing potential of vaccines not only in disease prevention but also in promoting healthy longevity among ageing populations.
