Immunisations at one year of age for children born on or after 1 July 2024

Updated 4 June 2025

Applies to England

Immunisations your baby will have at one year of age

Your baby will have 3 injections at their one year vaccination visit including:

1. Their MenB (meningococcal group B) booster vaccination.

2. A PCV13 (pneumococcal conjugate vaccine) booster vaccination against pneumococcal disease caused by some types of pneumococcal bacteria.

3. Their first MMR vaccination against measles, mumps and rubella.

Complete your course of immunisations

Routine vaccinations start with a priming dose as a baby. Get your child’s boosters at the right age, or soon after, to help provide life long protection.

Protecting against meningococcal group B disease, pneumococcal disease, measles, mumps and rubella

Meningococcal disease

Meningococcal disease is a serious infection that can also cause meningitis and septicaemia in children and young people.

Group B meningococcal bacteria (MenB) are currently responsible for most cases of meningococcal disease in the UK, while meningococcal group C (MenC) disease is now uncommon because of our successful vaccination programme against MenC

Which vaccines will be used

Your child will have a dose of MenB vaccine. These vaccines will be given in the muscle of the thigh or upper arm.

The MenB vaccine is called Bexsero, further information is available in the the Patient Information Leaflet.

Why your child will need booster vaccines

Booster vaccines are given to increase the protection given by the immunisations your baby has had earlier. The protection offered by the infant vaccinations starts to wear off but the booster helps to extend protection over the period of highest risk.

Side effects of the MenB vaccine

Your child may have redness, swelling or tenderness where they had the injection. About half the children who have these vaccines may become irritable, and some get a mild fever. You can get more information on this from your GP, practice nurse or health visitor.

Pneumococcal disease

Pneumococcal disease is one of the most common causes of bacterial meningitis in children but it also causes septicaemia, pneumonia, ear infections (otitis media) and other serious illnesses. There are more than 90 different types of pneumococcal bacteria.

Which vaccine will be used

The vaccine used is a booster dose of PCV13 (pneumococcal conjugate vaccine) which protects against 13 different pneumococcal types that most commonly cause pneumococcal disease in children. This vaccine will be given in the muscle of the thigh or upper arm at the same visit as the MMR and MenB vaccines.

The PCV vaccine is called Prevenar 13, further information is available in the Patient Information Leaflet.

Side effects of the PCV vaccine

Out of 10 babies immunised, 1 or 2 may get swelling, redness or tenderness at the injection site or get a mild fever.

Measles

Measles is caused by a very infectious virus. Nearly everyone who catches it will have a high fever, a rash and generally be unwell. The complications of measles include chest infections, fits (seizures), encephalitis (infection of the brain), and brain damage. In very serious cases, measles can kill.

Mumps

Mumps is caused by a virus which can lead to fever, headache, and painful, swollen glands in the face, neck and jaw. It can result in permanent deafness, viral meningitis and encephalitis (inflammation and swelling of the brain).

Rubella

Rubella is also caused by a virus. In children it is usually mild and can go unnoticed, but rubella in pregnancy is very serious for unborn babies. It can seriously damage their sight, hearing, heart and brain. This condition is called congenital rubella syndrome (CRS).

The MMR vaccine

MMR contains weakened versions of live measles, mumps and rubella viruses. Because the viruses are weakened, people who have had the vaccine cannot infect other people.

The MMR vaccine and gelatine

In the UK, we have 2 MMR vaccines which work very well. One of them contains gelatine and the other one doesn’t. If you would prefer to have the vaccine that does not contain porcine gelatine, talk to your practice nurse or GP. See the MMR vaccine Patient Information Leaflets at:

• Priorix
• MMRVAXPRO

How and when is the vaccine given?

The vaccine is injected into the muscle of the thigh or upper arm. It is given at one year of age after the immunity the baby got from their mother fades. A second dose of the vaccine should be given again at 18 months of age.

Effectiveness of the MMR vaccine

Since it was introduced in the UK in 1988, the MMR vaccine has dramatically reduced the 3 diseases (measles, mumps, rubella) in young children.

Side effects of the MMR vaccine

The 3 different viruses in the vaccine act at different times and may produce the following side effects after the first dose:

Six to 10 days after immunisation, as the measles part of the vaccine starts to work, about one in 10 children may develop a fever and some may develop a mild measles-like rash and go off their food.

About one in every 1,000 immunised children may have a fit caused by a fever – this is called a ‘febrile convulsion’. However, children who are not immunised and get measles are 3 times more likely to have a fit.

About 3 weeks after MMR vaccination, as the mumps part of the vaccine starts to work, some children may rarely get mumps-like symptoms (fever and swollen glands).

Very rarely, children may get a rash of small bruise-like spots in the 6 weeks after the vaccination. This is usually caused by the measles or rubella parts of the vaccine. If you see spots like these, take your child to the doctor to be checked. Your doctor will tell you how to deal with the rash and how to protect your child in the future.

Fewer than one in a million children may develop encephalitis (inflammation and swelling of the brain) after the MMR vaccine. However, if a child catches measles, the chance of developing encephalitis is between one in 200 and one in 5,000.

If your baby is allergic to eggs

The MMR vaccine can safely be given to children who have had a severe allergy (anaphylactic reaction) to egg. If you have any concerns, talk to your health visitor, practice nurse or doctor.

Watch out for meningitis and septicaemia

Both meningitis and septicaemia are very serious. It is important that you recognise the signs and symptoms and know what to do if you see them.

Early symptoms of meningitis and septicaemia may be similar to a cold or flu (fever, vomiting, irritability and restlessness).

However, individuals with meningitis or septicaemia can become seriously ill within hours, so it is important to know the signs and symptoms of these conditions.

Meningitis

Meningitis is an infection of the lining of the brain. Meningitis can be caused by several types of bacteria or viruses.

Infection with meningococcal bacteria can cause meningitis, septicaemia (blood poisoning), pericarditis (inflammation of the lining of the sac that contains the heart) and arthritis (swelling of the joints).

In babies, the main symptoms of meningitis may include:

• a high-pitched, moaning cry
• irritable when picked up
• a bulging fontanelle
• drowsy and less responsive – being difficult to wake
• floppy and listless
• stiff with jerky movements (convulsions or fits)
• refusing feeds, vomiting
• skin that is pale, blotchy or turning blue
• a fever

Septicaemia

Septicaemia is a very serious condition when the blood stream is infected. The signs of cold hands and feet, pale skin, vomiting and being very sleepy or difficult to wake can come on quickly. If you suspect septicaemia, get help urgently.

In babies, the main symptoms of septicaemia may include:

• rapid or unusual patterns of breathing
• skin that is pale, blotchy or turning blue
• fever with cold hands and feet
• shivering
• vomiting and refusing feeds
• red or purple spots that do not fade under pressure (do the glass test explained below)
• pain or irritability from muscle aches or severe limb or joint pain
• floppiness
• severe sleepiness

It is important to remember that not everyone will develop all the symptoms listed, and that this list of symptoms is not exhaustive.

If an individual develops some of the symptoms, especially red or purple spots, get medical help urgently. If you can’t get in touch with your doctor, or are still worried after getting advice, or if your baby (or anyone else) has symptoms of concern or a condition that is getting rapidly worse, trust your instincts and take your child to the emergency department of your nearest hospital.

The ‘glass test’

Press the side of a clear drinking glass firmly against the rash so you can see if the rash fades and loses colour under pressure. If it doesn’t change colour, contact your doctor immediately.

On dark skin, check inside the eyelids or roof of the mouth where the spots may be more visible
