MS, Cabinet Secretary for
Health and Social Services: On 14 November 2023, the Joint
Committee on Vaccination and Immunisation (JCVI) recommended a
universal varicella vaccination programme should be introduced as
part of the childhood immunisation schedule.
Varicella – commonly known as chickenpox – is a highly-contagious
infectious disease caused by the varicella zoster virus. The
virus is very common and affects most children, although it can
be caught for the first time at any age.
Most varicella cases in children are relatively mild and the
illness resolves without any need for treatment from a medical
professional. However, some children can develop complications,
such as bacterial infection or skin lesions, including group A
streptococcus, and in rare cases, encephalitis, pneumonitis and
stroke. These complications can result in hospitalisation and, on
rare occasions, death.
In its advice, the JCVI indicated the vaccination should be
offered in a two-dose programme at 12 and 18 months of age using
the combined MMRV (measles, mumps, rubella and
varicella) vaccine. There is evidence from other countries that
vaccination can decrease the number of cases of varicella and
prevent severe cases and other serious complications.
I have accepted the JCVI's advice, which includes the routine
programme and a catch-up for older children up to six-years-old
to prevent a gap in immunity. NHS Wales organisations will now
confirm planning assumptions for the introduction of the new
vaccination programme in Wales.
The introduction of the varicella programme will align with the
planned childhood immunisation schedule changes in January 2026,
which is when the new 18-month varicella vaccination appointment
will be introduced.
Vaccinations are the most effective way to prevent many
infectious diseases, providing protection for individuals and
wider protection for their communities. The introduction of
new vaccination programmes gives us hope that disease and
infection can be further reduced, both protecting our citizens
and reducing pressure on our health service.
This statement is being issued during recess to keep members
informed. Should members wish me to make a further statement or
to answer questions on this when the Senedd returns I would be
happy to do so.
