Helvetesild: Vaksinering
Det finnes to vaksiner mot helvetesild. Den ene vaksinen inneholder en genteknologisk fremstilt del av viruset, som får kroppen til å produsere beskyttende antistoffer. Denne er vist å kunne redusere forekomsten av herpes zoster med ca. 90 %, og den kan også brukes av personer med sykdommer med svekket immunforsvar (eks. kreftsykdommer og blodsykdommer). Denne vaksinen har langvarig og god beskyttelse og det er ikke foreløpig anbefalinger om behov for revaksinering (status 2025)
Den andre vaksinen inneholder et levende svekket virus, og er vist å kunne omtrent halvere andelen som får sykdommen. Denne vaksinen tas ikke lengre inn i norge.
Dersom du har hatt vannkopper og utsettes for ny smitte fra barn med vannkopper, ser det ut til at dette kan ha en slags vaksine-effekt. Slik kontakt kan redusere risiko for å få helvetesild noe, men ikke like mye som ved vaksinering.
