Researchers observed a rise in adult central nervous system (CNS) infections, primarily aseptic meningitis caused by the varicella zoster virus (VZV), post-2019. The researchers highlighted the potential of zoster vaccination to reduce CNS infections. Meanwhile, CNS infection by herpesviruses, including VZV, may contribute to the progression of dementia. Furthermore, the potential effect of zoster vaccines in preventing dementia progression by reducing VZV reactivation has also been highlighted.
