Immunosuppression and Vaccines: What Published Guidance Supports
Live vaccines can be dangerous in this group, and inactivated vaccines matter more than ever because infection risk is higher.
Key takeaways
- Live vaccines: generally contraindicated in significant immunosuppression
- Inactivated vaccines: safe, though the response may be reduced
- Most useful single change: Plan vaccinations before starting immunosuppressive treatment where possible.
- Commonest mistake: Live vaccines, including some travel vaccines, without specialist advice.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What it is
How vaccination changes for people whose immune systems are suppressed. It sits within Vaccinations. Here are the numbers, taken from the guidance cited at the end.

|---|---|
| Live vaccines | generally contraindicated in significant immunosuppression |
| Inactivated vaccines | safe, though the response may be reduced |
| Household contacts | should be vaccinated to protect the person |
| Timing | ideally before immunosuppressive treatment starts |

When to speak to a doctor
Seek urgent medical help for any fever if you are immunosuppressed, particularly during chemotherapy — neutropenic sepsis is a medical emergency. Contact your specialist team before any vaccination, and seek advice urgently after contact with chickenpox or measles.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
