CHILD IMMUNIZATION SCHEDULE 2025: UK EXPLAINED

CHILD IMMUNIZATION is the process of delivering a vaccination to your child against diseases Child immunization is one of the most effective ways to protect children from serious and potentially deadly diseases.

Why Child Immunization Matters

Saves Lives: Vaccines prevent 3.5 to 5 million deaths worldwide every year.
Protects Children: Immunization trains your child’s immune system to fight serious diseases like measles, polio, and whooping cough.
Prevents Spread: Vaccinated children help protect others too, especially those who can’t be vaccinated for medical reasons (herd immunity).
Reduces Healthcare Burden: Vaccines lower the need for hospital visits and costly treatments.
Supports Global Health: Child immunization helps prevent disease outbreaks and strengthens health systems—crucial in the fight against threats like antimicrobial resistance.

A Wake-Up Call

The COVID-19 pandemic disrupted routine vaccinations.
In 2024 alone, over 20 million children missed their first measles vaccine dose.
This shows how quickly immunity gaps can put lives at risk.

What is Vaccination ?

Vaccine is a product due to which immunity is provided to the body to fight exposure to diseases

What Vaccines DO:

Protect your child from serious and possibly deadly diseases – it’s one of the most effective steps you can take for their health.
Help stop disease from spreading – this protects everyone, especially those who are most vulnerable.
Go through extensive safety testing before being approved, and are constantly monitored for side effects.
Sometimes cause mild side effects like a sore arm or feeling tired—but these usually go away in a few days.
Help reduce or even eliminate diseases when enough people in the community are vaccinated.

What Vaccines DO NOT Do:

They do NOT overload the immune system – it’s completely safe to give multiple vaccines at once.
They do NOT contain mercury (thiomersal) or harmful ingredients – everything used in vaccines is there to make them safer and more effective, and only in tiny, controlled amounts.
They do NOT cause autism – extensive research has confirmed that there’s no link between vaccines (including MMR) and autism.

Why Child Immunization Is So Important

Vaccines are one of the most powerful tools we have to keep our children healthy. Since their introduction, diseases that once caused widespread death and disability—like smallpox, polio, and tetanus—are now rare or gone in many parts of the world.

But these diseases haven’t disappeared everywhere. Cases of illnesses like measles and diphtheria still happen, often related to international travel. And if vaccination rates drop, these diseases can come back quickly

In short: child immunization saves lives. It keeps your child safe, protects your loved ones, and helps create a healthier future for ever

What’s Changing in the UK Child Immunization Programme?

The UK’s child immunization schedule was updated on 1 July 2025, with more changes coming from 1 January 2026.

What vaccines your child will need — and when they’ll get them — depends on:
When your child was born, and
Which vaccines they’ve already had

What’s new after your child turns 12 months?

If your child was born on or after 1 July 2024, they’ll now follow the new child immunization schedule.

Here’s the updated routine vaccination timeline:

Your Child’s Updated Immunization Schedule

Here’s what to expect at each stage:

At 8 Weeks Old

Your baby will be offered their first set of routine vaccines:
Six-in-one vaccine – protects against diphtheria, tetanus, whooping cough, polio, Hib, and hepatitis B
Rotavirus vaccine – helps prevent severe diarrhoea
MenB vaccine – protects against meningitis B

At 12 Weeks Old

Second dose of the six-in-one vaccine
Second dose of the rotavirus vaccine
Second dose of the MenB vaccine

At 16 Weeks Old

Third dose of the six-in-one vaccine
First dose of the pneumococcal vaccine (PCV) – protects against serious infections like pneumonia

Around 1 Year Old

If your child was born on or after 1 July 2024:
MMR vaccine (first dose) – protects against measles, mumps, and rubella
Second dose of pneumococcal vaccine (PCV)
Third dose of the MenB vaccine

If your child was born on or before 30 June 2024:

MMR vaccine (first dose)

Second dose of pneumococcal vaccine (PCV)
Hib/MenC vaccine or a fourth dose of the six-in-one vaccine (depending on what they’ve already received)
Third dose of the MenB vaccine

New at 18 Months Old (starting 1 January 2026)

Only for children born on or after 1 July 2024
Fourth dose of the six-in-one vaccine
Second dose of the MMR vaccine
Children born before 30 June 2024 will not have an 18-month vaccination appointment.

From Age 2 to 15 Years

Annual flu vaccine – offered every year, up to and including Year 12 in school

At 3 Years and 4 Months Old

Children born on or after 1 July 2024:

Four-in-one booster – protects against diphtheria, tetanus, whooping cough (pertussis), and polio

Children born on or before 30 June 2024:

Four-in-one booster
Second dose of the MMR vaccine (if not already given at 18 months)

Between 12 and 13 Years Old

HPV vaccine – protects against human papillomavirus, which can cause cancers later in life

Around 14 Years Old and Older (Teenage Boosters)

Three-in-one teenage booster – top-up protection against diphtheria, tetanus, and polio
Meningococcal vaccine – protects against meningitis and blood poisoning
.It’s important to attend your child’s vaccination appointments when invited. These vaccines help protect them — and others — from serious diseases.

When and Where Will My Child Get Their Vaccines?

You don’t need to remember all the dates — the Child Health system or your GP surgery will send you reminders when it’s time to book your child’s vaccinations.

Some vaccines are given at your GP clinic, while others — like the flu vaccine or school-age boosters — are given at school. You’ll always be informed beforehand, and your permission will be requested.

What if My Child Misses a Vaccine?

It’s important to have vaccines on time for the best protection, but if your child misses one, don’t worry — just speak to your health visitor. They’ll help you catch up with the right vaccines safely.

You’ll continue to be invited for all your child’s routine immunizations as they grow.

Vaccines are safe, effective, and they save lives.

Information for Parents of Premature Babies

If your baby was born early, they may be more at risk of certain infections. That’s why they should still start the routine child immunization schedule from 8 weeks after birth, no matter how early they arrived.

Giving Paracetamol to Premature Babies

Some babies can get a fever after the MenB vaccine. If your baby has left hospital care, it’s a good idea to have infant paracetamol at home before the vaccine appointment.

If your baby was born before 32 weeks, ask your doctor for the right dose based on their weight.

Allergic Reactions to Vaccines – What You Should Know

Very rarely, a baby may have an allergic reaction to a vaccine. Signs to look out for include:

A rash or itchy skin
Breathing difficulties or sudden collapse (a serious condition called anaphylaxis)

Though this can sound scary, anaphylaxis is extremely rare and can be treated quickly. Babies usually make a full recovery.

If your baby has ever had a reaction to a previous vaccine, make sure you tell the nurse or doctor before their next appointment.

Why These Vaccines Are Important

Protection against Hib (Haemophilus influenzae type b) can drop as your child gets older — a booster helps keep immunity strong.

Giving the second MMR dose earlier (at 18 months) helps protect your child from measles before they start nursery.

Special Cases: Hepatitis B and High-Risk Babies

If your baby is considered high risk — for example, if you have hepatitis B — they will follow a slightly different vaccine plan:
Doses are given at birth, 4, 8, 12, and 16 weeks.
From July 2025, there’s no longer a need for a separate hepatitis B booster at 12 months.
Instead, a final booster will be given at 18 months as part of the hexavalent vaccine (the six-in-one).

What About Preschool Boosters at Age 3 Years 4 Months?

For now, nothing changes here. Your child will still receive:
The dTaP/IPV booster – protection against diphtheria, tetanus, whooping cough, and polio
The second MMR dose – unless they already had it at 18 months
However, from late 2027, this appointment may change, as the 18-month MMR dose becomes the standard.

Why are changes being made to the child immunization schedule?

The new child immunization schedule is designed to give babies better protection, right from the start. By updating the timing and types of vaccines, the goal is to:

Protect children earlier, especially from serious illnesses like Meningitis B
Make visits easier, by reducing how many injections are given at once
Simplify the vaccine schedule, so it’s easier for families and healthcare teams to follow

These changes help ensure your child gets the best protection at the right time, with fewer appointments and less stress. It’s all part of improving the child immunization journey for both you and your little one.

Understanding the Risks and Myths Around Child Immunization

Why Some Parents Worry

It’s completely normal to have concerns about child immunization. Many parents want to make sure the benefits of vaccines outweigh any risks — and that’s a good thing.

Are There Risks?

All medicines can have side effects, but vaccines are among the safest. Most babies only get mild effects like:
A small red bump or swelling where the injection went in
A slight fever, which usually goes away in a day or two
Serious side effects are extremely rare, and medical staff are trained to handle them quickly.

Common Myths About Vaccines

You may have seen stories online linking vaccines to conditions like autism. These claims can be worrying — but they’ve been thoroughly debunked by scientific research.
There’s no proven link between the MMR vaccine and autism or any other long-term condition.
If you’re unsure or concerned, talk to your health visitor. They can give you trusted, up-to-date advice.

Breastfeeding and Baby’s Immunity

Breastfeeding helps protect your baby by passing on helpful antibodies. It can:
Reduce the risk of infections
Strengthen your baby’s immune system
Even support your baby’s response to vaccines
But whether you breastfeed or not, the same child immunization schedule applies.

When Might a Vaccine Be Delayed?

In some cases, your baby’s vaccines may need to be postponed. Always tell your nurse or doctor if your baby:
Has a high fever, vomiting, or diarrhoea on the day of the appointment
Has had seizures or serious reactions to past vaccines
Has allergies or a bleeding disorder
Is being treated for cancer or has a weak immune system (e.g. due to HIV, leukaemia, or certain medications)
This helps your healthcare team decide the safest way to protect your child.

A family history of illness usually doesn’t mean your baby can’t be vaccinated.

Understanding Child Immunizations: A Parent’s Guide

As parents, we all want to do everything we can to protect our children and give them the healthiest start in life. One of the simplest and most effective ways to do that is through immunizations.

Vaccines help protect your child from serious diseases like measles, whooping cough, polio, and more. These illnesses may seem like things of the past, but they can still show up—and when they do, they can be dangerous, especially for young children.

Immunizations help your child’s immune system learn how to fight off these threats before they ever get sick.

Here’s the good news: Vaccines are safe, carefully tested, and recommended by doctors all over the world. Most side effects are mild—like a sore arm or a low-grade fever—and they usually go away quickly.

A few tips for parents:

Keep a record of your child’s vaccinations—this will come in handy for school, travel, and other activities.
Follow the recommended schedule—it’s designed to protect your child when they’re most vulnerable.
Don’t hesitate to ask for support—no question is too small when it comes to your child’s well-being.
At the end of the day, vaccines aren’t just about protection—they’re about peace of mind. Knowing your child is guarded against preventable diseases lets you focus on all the beautiful moments of growing up, without unnecessary worry.

According to the World Health Organization (WHO):

The World Health Organization (WHO) has listed vaccine hesitancy as one of the biggest threats to global health.They emphasize about child immunizations against several diseases and to make your child vaccinated and protected.

Conclusion:

In conclusion, child immunization and vaccination are not just medical routines—they are acts of love, protection, and responsibility. Every vaccine given is a step toward a healthier future, shielding children from diseases that once claimed millions of young lives.

When parents choose to immunize their children, they are giving them a stronger start in life, filled with more opportunities to grow, learn, and thrive. Vaccines don’t just protect one child—they protect entire communities.

They build a circle of safety around families, schools, and society as a whole. In a world where so much is uncertain, child immunization remains a proven and powerful way to ensure our children grow up healthy and safe. It’s a quiet promise we make to them—a promise of care, health, and hope for tomorrow.
