Medical researchers say a new vaccine could offer nearly double the protection against shingles, as compared to the previous vaccine.
The CDC's Advisory Committee on Immunization Practices recently named Shingrix the preferred vaccine, and recommended it for all adults over age 50. Clinical trials have shown Shingrix prevents more than 90% of shingles cases. The previous vaccine, Zostavax, only prevents about half of shingles cases in those over 60.
The Centers for Disease Control and Prevention estimates about one in three people in the United States will develop shingles in their lifetime, with many of these cases happening to adults 60 and older. Shingles is caused by reactivation of the varicella zoster virus, the same virus that causes chickenpox, and often results in a painful, blistering rash.
