Researchers Explore Shingles Vaccine Protective Role Against Dementia

Varicella zoster virus (VZV), one of 8 herpesviruses known to infect humans, “is a really sneaky virus,” said neurovirologist Maria Nagel, M.D., in an article posted by the JAMA Network on October 18, 2024.

Herpes Zoster, known as shingles, has been a vaccine-preventable disease for several years.

“Our aging population is growing, and it’s really concerning that 1 in 9 people over 65 have Alzheimer’s,” Nagel added. “It’s critical that we figure out what to do about this disease.”

Could the infection increase people's risk for dementia? Conversely, could shingles vaccination protect against dementia? And what about adult vaccines against other infections?

The unedited article - Researchers Are Exploring the Role of Shingles—and a Protective Role of Shingles Vaccine—in Dementia, is posted at this JAMA link.

As of October 19, 2024, various approved shingles vaccines are offered worldwide.
