In rare cases, shingles has other serious consequences. Blisters can become infected. A rash on the face can spread shingles into eyes, which can lead to loss of vision, sometimes permanent. A rash around the ear can cause a complication known as Ramsey Hunt syndrome, which can include deafness and weakness of the facial muscles.
A big unknown is whether people who got the chicken-pox vaccine as children will be susceptible to shingles in later years or protected from it—or even vulnerable to full-blown chicken pox if their immunity has weakened. Since the chicken-pox vaccine was only approved in 1996, it will be several decades before the first generation of Americans to be widely vaccinated reaches the typical shingles years.
