What is the minimum interval between doses of Shingrix?

The recommended interval between Shingrix doses is 2 to 6 months. The minimum interval between doses of Shingrix is 4 weeks. If the second RZV dose is given more than 4 days sooner than 4 weeks after the first dose, a valid second dose should be repeated at least 4 weeks after the dose given too early.

For adults who are or will be immunodeficient or immunosuppressed and who would benefit from a shorter vaccination schedule, the second dose can be administered 1–2 months (a minimum of 4 weeks) after the first dose.
