How Effective is Shingles Vaccine?


According to the CDC, the vaccine reduced shingles by about half (51%) in adults 60 years and older.1 The manufacturer product insert states: “Vaccination with Zostavax does not result in protection of all vaccine recipients. The duration of protection beyond 4 years after vaccination with Zostavax is unknown. The need for revaccination has not been defined.”2 However, efficacy studies showed a significant decrease in vaccine effectiveness one-year post-vaccination and by nine years, Zostavax was determined to be no longer effective at preventing shingles.3

Shingrix vaccine is estimated to reduce shingles by over 90% in adults 50 years and older.4 The length of protection from Shingrix past 4 years is unknown.5
