Dr Yiannis Ioannou, Consultant Paediatrician, explains important updates to the UK’s childhood vaccination schedule that parents should be aware of.

From 1 July 2025, the UK’s childhood immunisation schedule has undergone several important updates. These changes reflect the latest advice and are designed to better safeguard children against serious illnesses. One of the most notable additions is the introduction of the chickenpox (varicella) vaccine, which will be available free on the NHS from January 2026.

Here’s a simple breakdown of what’s changing and why it matters.

What’s new in the vaccination schedule?

Chickenpox vaccine added to NHS programme

Starting January 2026, eligible children will receive a combined MMRV vaccine (measles, mumps, rubella, and varicella) as part of their routine immunisations.  

This vaccine has been used safely for decades in countries like the US and Australia. It helps prevent chickenpox and its complications, such as bacterial infections, pneumonia, and even stroke. 

Why it matters: Chickenpox can cause serious illness and lead to missing school and work for families.

Earlier protection against Meningococcal B (MenB)

The second dose of MenB will now be given at 12 weeks instead of 16.  

Why it matters: Young infants are most vulnerable to illnesses caused by the Meningococcal bacteria (MenB), so earlier vaccination offers better protection during this critical period.

Previous Next

Pneumococcal vaccine (PCV13) timing adjusted

The first dose of PCV13 is now given at 16 weeks instead of 12.  

Why it matters: This change helps spread out injections more evenly across appointments, making visits less stressful for babies and parents. 

Previous Next

Hib/MenC vaccine removed at 12 months

Children born on or after 1 July 2024 will no longer receive the Hib/MenC (Menitorix®) vaccine at 12 months. 

Why it matters: High coverage in adolescents means that infants are already well protected indirectly. There are alternative Meningitis C vaccines available for infants if required, but will not be offered on the NHS schedule.

New 18-month appointment introduced

From January 2026, children will be invited for a new 18-month vaccination appointment, which includes: 

  • a booster dose of the hexavalent vaccine (protects against diphtheria, tetanus, pertussis, polio, Hib, and hepatitis B) 
  • the second dose of the MMR vaccine  

Why it matters: This change improves uptake and ensures children are protected before starting nursery or school.

Summary of key changes

  • 12 weeks: MenB (2nd dose) 
  • 16 weeks: PCV13 (1st dose) 
  • 12 months: No Hib/MenC for children born after 1 July 2024 
  • 18 months: New appointment including Hexavalent booster + MMR (2nd dose) 
  • January 2026: Chickenpox vaccine added via MMR
