New MMRV (Measles, Mumps, Rubella & Varicella) Vaccine

From 1st January 2026, the NHS routine childhood vaccination schedule has changed and the previous MMR vaccine has now been replaced with the MMRV vaccine, which adds chickenpox (varicella) protection. As a result, GP practices can no longer obtain separate MMR vaccines, nor offer standalone chickenpox vaccines, as MMRV is the standard vaccine now given to young children as part of their routine schedule.

FAQs:

What Is the MMRV Vaccine?

The MMRV vaccine protects against four infectious diseases; Measles, Mumps, Rubella and Chickenpox (Varicella). It is given in two doses at 12 and 18 months. This schedule applies to children born on or after 1st January 2025, while older children may receive MMRV depending on their date of birth. The vaccine has been used successfully in many other countries for years.

Why Has the Vaccine Changed?

The Joint Committee on Vaccination and Immunisation (JCVI) recommended introducing varicella protection into the routine schedule using a combined vaccine, rather than adding an extra injection as evidence shows strong, long‑lasting immunity against chickenpox and a significant reduction in complications.

Can My Child Still Receive the MMR Vaccine?

Children who are now part of the updated routine schedule will no longer receive MMR alone, as MMR has been withdrawn for these cohorts. MMR remains available only for older children and adults (born on or before 31st December 2019) who never completed their earlier courses.

Can My Child Have Chickenpox Vaccination on Its Own?

No. Standalone varicella vaccination is not available on the NHS as part of routine general practice care. The NHS provides chickenpox protection only as part of the combined MMRV vaccine. Private clinics may offer separate varicella vaccination, but this is not provided by NHS GPs.

Is It Safe to Have MMRV After an Earlier MMR Dose?

Yes. Some children will already have received an MMR dose at 12 months. They can safely receive MMRV later on to add protection against chickenpox. Both vaccines are live attenuated and considered safe, effective, and interchangeable according to UKHSA guidance.

Can my child still have the MMRV if I have already given him/her the chickenpox vaccine privately? 

Yes, you cannot overdose on the vaccine and quite safe to give again.

Is It Safe? Are There Side Effects?

MMRV is very safe and has been widely used internationally for many years. Common, mild side effects include a mild fever or rash or slight soreness at the injection site, or more rarely, a small number of children may develop a few chickenpox‑like spots, this is usually harmless and resolves quickly. If your child is unwell on the day of vaccination or has underlying conditions affecting immunity, please discuss this with us.
