Vaccine Hesitancy: Sorting the Evidence From the Noise
It is usually the product of specific unanswered concerns rather than a fixed position, and it responds to information far better than to argument.
Key takeaways
- WHO: lists it among the top global health threats
- Most common driver: specific safety concerns, not opposition in principle
- Most useful single change: Ask what the specific concern is rather than assuming it.
- Commonest mistake: Arguing, which reliably entrenches a position.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
What it is
Delay or refusal of vaccination despite availability. It sits within Vaccinations. The figures below are the ones published guidance uses, rather than the ones that circulate.
The numbers, in one place
| Measure | Figure |
|---|---|
| WHO | lists it among the top global health threats |
| Most common driver | specific safety concerns, not opposition in principle |
| What works | addressing the actual concern; correcting a myth rarely does on its own |
| Measles herd immunity | needs about 95 per cent coverage |
What helps
These are worth doing. None of them needs to happen all at once.
- Ask what the specific concern is rather than assuming it
- Use named sources: NHS, UKHSA, MHRA
- Acknowledge that asking questions about a medicine is reasonable
What to avoid
Things that seem reasonable and are not.
- Arguing, which reliably entrenches a position
- Dismissing a concern rather than answering it

When to speak to a doctor
Speak to a GP or practice nurse about any specific concern; they can check your individual circumstances, including conditions or medicines that genuinely change what is recommended. Seek urgent help for a rash that does not fade under pressure, or a seriously unwell child.
Where this comes from
- World Health Organization — vaccine hesitancy

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.
