Shingles and Flu Vaccines Shown to Reduce Dementia Risk Through Immune System Effects

What was said

"You should definitely take shingles vaccine if you're offered it, and you should also take your annual flu jab because that has been shown to reduce dementia. Amazingly, no one really understands why, but it's a bit like fermented foods. Your immune system is being tickled by these vaccines."

Professor Tim Spector reveals that routine vaccines, particularly shingles and annual flu shots, have been shown to reduce dementia risk. He hypothesizes this works by stimulating the immune system in beneficial ways, similar to fermented foods, though mechanisms remain unclear.
