Timing of Shingles Vaccine After Having Shingles
You should wait at least 2 months after the acute shingles episode has resolved before receiving the shingles vaccine, with Shingrix (recombinant zoster vaccine, RZV) being the strongly preferred option over Zostavax. 1, 2, 3
Recommended Waiting Period
The minimum interval is 2 months after the shingles episode, allowing for complete resolution of acute symptoms and immune system recovery to optimize vaccine response. 2, 3
This 2-month recommendation is based on documented evidence showing this represents the minimum interval between herpes zoster episodes and potential recurrence. 2
Different countries have varying recommendations: the USA and Germany recommend waiting until acute symptoms have resolved (minimum 2 months), while Canada, Ireland, and Australia recommend waiting at least 1 year. 2
Why Vaccination After Shingles Is Critical
Having one episode of shingles does NOT provide reliable protection against future recurrences. 1, 2
The cumulative risk of shingles recurrence is substantial: 2.5% at 2 years, 6.6% at 6 years, and 10.3% at 10 years. 2, 3
Vaccination after a shingles outbreak significantly reduces this recurrence risk. 1
Vaccine Choice and Dosing Schedule
For Immunocompetent Adults:
Shingrix (RZV) is the preferred vaccine due to superior efficacy (97.2% in adults ≥50 years) compared to the older Zostavax. 1, 4
Administer as a 2-dose series with the second dose given 2-6 months after the first dose. 1, 3
Protection persists for at least 8 years with minimal waning (maintaining >83.3% efficacy). 1
For Immunocompromised Adults:
Shingrix remains the preferred option as it is a non-live vaccine, unlike Zostavax which is contraindicated in immunocompromised patients. 5, 1, 3
A shorter schedule may be used with the second dose given 1-2 months after the first dose. 1, 3
Consider deferring vaccination until after holding immunosuppressive medication for an appropriate period before and 4 weeks after vaccination to ensure robust immune response. 5, 2
Important Clinical Pitfalls to Avoid
Do not confuse the 2-month waiting period after shingles with the 2-6 month interval between vaccine doses—these are separate timeframes. 2
Do not delay vaccination beyond the 2-month minimum, as this increases the risk of recurrence without providing additional benefit. 2
Do not use live zoster vaccine (Zostavax) in immunocompromised patients—this is an absolute contraindication. 5, 1, 3
For patients previously vaccinated with Zostavax, Shingrix should be given at least 2 months after the Zostavax dose, as Zostavax efficacy wanes dramatically over time (only 14.1% by year 10). 1
Expected Side Effects
Injection-site reactions are common (9.5% experience grade 3 reactions vs. 0.4% with placebo), including pain, redness, and swelling. 1
Systemic symptoms occur in 11.4% of vaccine recipients versus 2.4% in placebo recipients. 1
Despite these side effects, no serious safety concerns have been identified in large clinical trials. 1
The dropout rate for the second dose is slightly higher in vaccinated individuals (1% increased risk), but completing both doses is essential for optimal protection. 1
