Routine vaccinations and boosters (Routine immunisation and booster vaccination (UK schedule))
Vaccines and booster doses that keep your protection against serious infections up to date through adult life, following the current UK immunisation schedule.
✓ Medically reviewed by a GMC-registered consultant · last reviewed September 2026 · next review September 2027 · how we review
In short
- Routine vaccines and boosters keep your protection against serious infections topped up through life.
- Most routine vaccines and boosters are free on the NHS for eligible groups; private vaccination is mainly for convenience or those outside eligibility.
- Protection builds over days to a couple of weeks, and some vaccines need a course or repeat doses.
- Exactly which vaccines you are offered, and at what age, can depend on your date of birth and on which UK nation you live in — England, Scotland, Wales and Northern Ireland each publish their own schedule and send their own invitations.
- Vaccines are well studied and safe for most people — there is no link between MMR and autism — but tell the clinician about allergies, pregnancy or a weakened immune system.
A plain-English summary. The detail — including risks and recovery — is below.
At a glance
A general guide. Your GP will give you advice for your situation.
Protects you against serious, sometimes life-threatening infections
Live vaccines (such as MMR) are generally not given in pregnancy or to people with significant immunosuppression — an individual plan is needed.
A sore arm, mild fever or tiredness can occur and usually settles. Paracetamol can help; normal activities are usually fine.
A clear record of what was given and what doses remain.

Protection builds over this time. You are not necessarily protected the moment you are vaccinated, so it is best...
Some vaccines need more than one dose. Return for the remaining doses on schedule for full protection.
Some vaccines (such as flu each autumn) or boosters at particular ages are repeated. Your practice can remind you...
What are routine vaccinations and boosters?
Vaccines train your immune system to recognise and fight specific infections without you having to catch the disease first. The UK has a routine immunisation schedule, set by expert bodies and published in the 'Green Book', which lists which vaccines are offered, to whom, and when. The Green Book is the clinical guidance used across the whole UK, but England, Scotland, Wales and Northern Ireland each publish their own patient schedule and arrange their own invitations, so the exact ages, doses and the way you are called in can differ depending on where you live. The schedule is also updated over time, so which vaccines you were offered — and when — can depend on your date of birth. If you are unsure what applies to you, check the NHS information for your own nation or ask your GP practice.
Protection from some vaccines fades over time, so 'boosters' top it up — for example the tetanus, diphtheria and polio booster, or repeat doses in childhood. Other vaccines are offered at particular ages or to particular groups, such as the shingles and pneumococcal vaccines for older adults, the flu vaccine each autumn for those at higher risk, and vaccines in pregnancy to protect the baby.
Vaccines are among the most studied treatments in medicine. The schedule is based on large amounts of safety and effectiveness data, and is updated as evidence changes. Importantly, there is no link between the MMR vaccine and autism — this has been thoroughly investigated and disproven, and measles itself can be very serious.
The aim of this guide is to help you understand what routine vaccines and boosters protect against, who they are for, and how to check you are up to date — not to pressure you, but because being protected matters.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
NHS routine vaccination vs private
| Feature | NHS routine | Private |
|---|---|---|
| Cost | Free if eligible | Paid |
| Who it's for | Eligible age/risk groups | Anyone, including outside NHS eligibility |
| Recorded on GP record | Yes | Should be shared with your GP |
| Best for | Most people on the schedule | Convenience or non-eligible groups |
Check NHS eligibility first — most routine vaccines and boosters are free for the groups they are meant for. Private vaccination is useful for speed or if you fall outside NHS criteria.
Preparing for your treatment
- Find out which vaccines you are due or eligible for — your GP practice can check your record.
- Bring your vaccination history or red book if you have one, so gaps are filled and doses not repeated.
- Tell the clinician about allergies, especially any previous reaction to a vaccine.
- Mention pregnancy or possible pregnancy, as this affects which vaccines are suitable.
- Mention a weakened immune system or medicines that affect it, as some 'live' vaccines may not be suitable.
- Raise any worries honestly — a good clinician will answer questions about safety and ingredients without pressure.
- Wear a top that lets you bare your upper arm easily.
What happens
The clinician (usually a practice nurse, pharmacist or GP) checks which vaccines you are due or eligible for and asks a few questions about your health, allergies, pregnancy and any previous reactions.
They explain what each vaccine protects against and answer your questions. The vaccine is then given, usually as an injection into the upper arm, and takes only a few seconds. If several vaccines are due, more than one may be given at the same visit, often in different arms.
You may be asked to wait a short while afterwards in case of an immediate reaction, which is rare. The vaccines you receive are recorded, and you should make sure they reach your NHS GP record.
Is this treatment right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Live vaccines (such as MMR) are generally not given in pregnancy or to people with significant immunosuppression — an individual plan is needed.
- A vaccine should not be given if you have had a confirmed serious allergic reaction (anaphylaxis) to a previous dose or a component, without specialist advice.
- Routine vaccination is usually deferred during a significant feverish illness.
- Vaccination is not a substitute for other measures where protection is incomplete, such as good infection precautions for high-risk individuals.
Delay or rearrange if…
- You have a significant feverish illness on the day; minor coughs and colds are usually fine.
- You are pregnant and the vaccine is a live vaccine not recommended in pregnancy.
- You have recently started treatment that strongly affects your immune system — check timing first.
- You have had a recent dose of a vaccine that requires a gap before the next, or recent blood products that may affect some live vaccines.
Alternatives to discuss
- Free NHS vaccination if you are within the eligible group, rather than paying privately.
- A catch-up schedule through your GP if you have missed doses.
- Non-vaccine protection for those who cannot be vaccinated, including others around them being vaccinated.
- Specialist advice for complex situations, such as significant immunosuppression.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Protects you against serious, sometimes life-threatening infections
- Keeps fading protection topped up so you stay covered through life
- Protects people around you, including those who cannot be vaccinated
- Reduces the chance of complications, hospital admission and long-term harm from these diseases
- Vaccines in pregnancy pass protection to the newborn baby
- A simple, quick appointment with long-lasting benefit
Risks & complications
- A sore, red or swollen arm where the vaccine was given
- Mild fever, headache, tiredness or aching for a day or two
- Feeling generally off colour briefly after the vaccine
- More than one sore arm if several vaccines are given at once
- A larger local reaction or a short flu-like illness
- Fainting around the time of the injection, more from the needle than the vaccine
- A mild rash a week or so after some 'live' vaccines such as MMR
- A significant allergic reaction soon after vaccination (staff are trained and equipped to treat this)
- Very rare specific reactions linked to particular vaccines, which your clinician can discuss
Serious reactions to routine vaccines are rare, and the risks from the diseases they prevent are generally far greater. The most important things to tell the clinician are any previous serious allergic reaction to a vaccine, pregnancy, and any condition or medicine that weakens your immune system, as these affect which vaccines are safe for you. Worries about discredited claims, such as a link between MMR and autism, should be raised openly — the evidence clearly shows no such link.
Published figures to discuss
Serious adverse reactions to routine vaccines are rare, and the risks from the infections they prevent are generally far greater. Exact rates differ for each vaccine and for each person's circumstances, and are best discussed against your own health. Because individual vaccine risks are specific, no single percentage applies across all routine vaccines; ask your clinician about the particular vaccines being offered.

| Local soreness, fever or aches | Common and short-lived | Most vaccine side effects reflect the immune response and settle without treatment. | Guide sourcesClinical context |
| Anaphylaxis | Rare; UK vaccination guidance describes it as very rare | Vaccinators should be trained and equipped to treat immediate allergic reactions. | Guide sourcesClinical context |
| Live vaccine given when contraindicated | Avoidable | Pregnancy, immunosuppression and some allergies need checking before live vaccines. | Guide sourcesClinical context |

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
Most people carry on as normal after a routine vaccine. A sore arm or feeling mildly off for a day or two is common and settles on its own. 'Afterwards' is mainly about letting protection build.
- A sore or slightly swollen arm for a day or two
- Mild fever, tiredness or aching that settles quickly
- A mild, short-lived rash after some live vaccines such as MMR
- Needing to return for a further dose of a vaccine course
Aftercare
- Treat a sore arm or mild fever with rest, fluids and paracetamol if needed.
- Complete any vaccine course on schedule for full protection.
- Keep a record of which vaccines you have had and when.
- Make sure private or pharmacy vaccinations are added to your NHS GP record.
- Note when you are next due, especially for seasonal vaccines such as flu.
- Carry on as normal; you do not usually need to avoid activity unless you feel unwell.
- Raise any ongoing concerns about side effects or eligibility with your GP.
- List of vaccines you are due or eligible for
- Vaccination history or red book gathered
- Note of any allergies or previous reactions
- Awareness of pregnancy status if relevant
- Plan for any follow-up doses in a course
- Way to add the vaccine to your NHS GP record
⚠ Get urgent help if…
- Difficulty breathing, swelling of the face, lips or throat, or a widespread rash soon after a vaccine — call emergency services
- A high fever that does not settle, or a fever with a stiff neck, severe headache or rash
- A vaccination-site reaction that becomes increasingly red, hot, swollen or painful after a couple of days (possible infection)
- Feeling faint or unwell for more than a short time after the injection
- Any new, severe or unexpected symptom you are worried about following vaccination
- Fainting that caused a fall or injury at the time of the vaccine
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

Results & realistic expectations
A good outcome is being up to date and protected against the infections the schedule covers for your age and health. Vaccination greatly reduces your risk of these diseases and their complications, although no vaccine is 100% effective for every person, so a small number of vaccinated people can still catch a milder form.
Protection from some vaccines fades over years, which is why boosters exist. Keeping a record and knowing when you are next due means you stay covered rather than letting protection lapse.
How long protection lasts varies by vaccine. Some give long-lasting or lifelong protection after a full course; others, such as flu, need repeating each year because the infection changes. Tetanus, diphtheria and polio protection is topped up by boosters over childhood and teenage years, with extra doses sometimes advised after certain injuries or for travel. Your clinician can advise when, if ever, you need another dose.
Related tests, treatments or support
Several vaccines can usually be given safely at the same appointment, often in different arms, which is convenient if more than one is due. Routine vaccines are sometimes given alongside travel vaccines, and some, such as flu and COVID-19, may be offered together in season. Your clinician will advise on any timing rules between specific vaccines.
Follow-up & long-term care
Follow-up is mainly about completing any course and keeping your record current. Make sure all vaccines, including private or pharmacy ones, reach your NHS GP record. Your practice can flag when you become eligible for age-based vaccines (such as shingles or pneumococcal) or are due a seasonal vaccine such as flu.
- Have seasonal vaccines, such as flu, each year if you are eligible.
- Keep boosters up to date as advised, including after certain injuries for tetanus.
- Take up age-based vaccines (such as shingles, pneumococcal, RSV) when you become eligible.
- Keep a personal vaccination record and make sure your NHS GP record matches it.
Repeat, follow-on and what comes next
- Some vaccines need more than one dose, or repeat doses (such as flu yearly) to maintain protection.
- Protection from some vaccines fades over years, which is why boosters are scheduled.
- Catch-up is often possible for missed childhood doses without restarting from scratch.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear record of what was given and what doses remain.
- Honest answers to questions about safety and side effects.
- A reminder system for seasonal or age-based vaccines.
- Vaccines recorded and shared with the NHS GP so the immunisation record stays complete.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Which vaccines you need and whether you are within NHS eligibility for them.
- Whether the vaccine itself, or just the appointment, is charged when given privately.
- The number of doses needed to complete a course.
- Whether several vaccines are given in one visit or across separate appointments.
- The provider type (GP practice, pharmacy or private clinic) and their fees.
- Any additional consultation to discuss suitability or catch-up planning.
- Which vaccines are included and the price of each (if private).
- Whether you are eligible for any of these free on the NHS instead.
- The number of doses needed and the cost of the full course.
- Whether a consultation fee is charged separately.
- Whether the vaccination will be recorded and shared with your NHS GP.
- Any follow-up appointment costs for further doses.
On the NHS? Most routine vaccines and boosters are free on the NHS for the age or risk groups they are intended for; private vaccination is mainly for convenience or for people outside NHS eligibility.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not explaining what each vaccine protects against or its common side effects.
- Dismissing genuine worries rather than answering them with evidence.
- Failing to check pregnancy status or immune status before a live vaccine.
- Charging privately for a vaccine the person is eligible to receive free on the NHS without saying so.
- Not recording the vaccine so the NHS GP record becomes inaccurate.
Marketing red flags
- Promoting vaccines based on fear rather than balanced evidence.
- Charging for vaccines without mentioning NHS eligibility.
- Implying a vaccine gives instant or 100% protection.
- Repeating discredited safety claims, or, conversely, dismissing all questions as 'anti-vax'.
Choosing a specialist safely
- Check the GP is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the GP who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good GP will welcome every one of these.
- Which vaccines and boosters am I due or eligible for right now?
- Are any of these unsuitable for me given my health, allergies or pregnancy?
- Which are free on the NHS and which would I pay for?
- How many doses do I need, and when should I come back?
- How long does each one protect me for, and when might I need another?
- Can these be given at the same time, and will they go on my GP record?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the GP who carries out my treatment, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this treatment not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
