1. Can I have Shingrix if I have already had shingles?
Yes. Having shingles does not provide lifelong protection against another episode. People who have previously had shingles can still receive Shingrix if they are in an age or risk group for whom zoster vaccination is recommended.
2. How long should an immunocompetent person wait after shingles before having Shingrix?
In Australia, immunocompetent people are advised to wait at least 12 months after an episode of shingles before receiving Shingrix. This is because the shingles episode itself boosts natural cellular and antibody immunity, and this increased immunity appears to persist for at least a year.
3. Why wait 12 months after shingles?
The reason for waiting is not because Shingrix is unsafe soon after shingles. Rather, shingles naturally boosts immunity, and the risk of another episode is relatively low during the first 12 months. Waiting allows this natural immune boost to provide protection before vaccination.
4. Can Shingrix be given 3 months after shingles?
Yes, 3 months can be appropriate for people who are immunocompromised. The Australian Immunisation Handbook states that immunocompromised people can receive Shingrix from 3 months after the acute illness, with the exact timing individualised according to their risk of recurrence and other clinical circumstances.
5. Why is the interval shorter for immunocompromised people?
Immunocompromised people have a higher risk of recurrent shingles and potentially severe complications. The benefit of providing vaccine protection earlier may therefore outweigh the potential benefit of waiting 12 months for the natural immune boost to persist.
6. Does 12 months versus 3 months affect the safety of Shingrix?
There have been no identified safety or immunogenicity concerns with giving Shingrix after a previous episode of shingles. The difference between 12 months and 3 months is primarily about balancing the natural immunity gained from the shingles episode against the higher risk of recurrence in immunocompromised people.
7. What if I am immunocompetent but have a high risk of shingles recurrence?
The standard Australian recommendation remains to wait at least 12 months after shingles if you are immunocompetent. Individual circumstances can be discussed with your doctor, particularly if your immune status or medical situation is changing.
8. Does having shingles mean I no longer need two doses of Shingrix?
No. A previous episode of shingles does not replace the recommended Shingrix vaccination schedule. Immunocompetent adults who are recommended to receive Shingrix generally require two doses, usually 2–6 months apart. Immunocompromised adults generally receive two doses 1–2 months apart.
9. Does the 12-month rule apply to everyone?
No. The 12-month recommendation applies to immunocompetent people after shingles. For immunocompromised people, Shingrix can be given from 3 months after the acute illness, with timing determined on an individual basis.
10. What is the practical rule for Shingrix after shingles?
For an immunocompetent person: wait at least 12 months after shingles. For an immunocompromised person: consider Shingrix from 3 months after the acute illness, depending on individual risk. This distinction is important because immunocompromised people have a substantially higher risk of recurrent and complicated shingles.
