The Joint Committee on Vaccination and Immunisation (JCVI) published advice recommending that a routine childhood varicella (chickenpox) vaccine be added to the UK immunisation schedule. UKHSA and NHS England have been working through implementation, and while the exact national rollout arrangements continue to evolve, community pharmacies are already fielding questions from parents — who has access, when it is given, what it costs privately, and what difference it makes.
This article answers the questions most commonly asked at the counter, grounded in the Green Book, JCVI advice and NICE guidance.
What chickenpox is
Chickenpox is the clinical illness caused by the varicella-zoster virus (VZV). In most children it is a self-limiting rash-and-fever illness lasting five to seven days. The complications that concern clinicians are secondary bacterial skin infection, pneumonia, encephalitis and — in adults, neonates, pregnant women and the immunocompromised — substantially more severe disease. NICE CKS on chickenpox sets out the standard pharmacy-counter advice: paracetamol for fever (avoid ibuprofen because of a signal for severe skin infection), calamine or chlorphenamine for itch, and red-flag referral criteria.
What the vaccine is
Two varicella vaccines are available in the UK: Varivax (MSD) and Varilrix (GSK). Both are live attenuated vaccines, given by subcutaneous injection, with a two-dose schedule.
FAQ
Is the vaccine now part of the routine NHS schedule for all children?
JCVI has recommended adding varicella to the routine childhood schedule. Implementation is underway but uptake on the NHS varies locally during the rollout. Check the current NHS schedule for confirmation of eligibility in your area. The Green Book remains the authoritative clinical reference.
What is the recommended age and interval?
The JCVI recommendation proposes a combined MMRV or separate varicella vaccine given alongside the existing MMR schedule points, with a two-dose course. The Green Book contains the definitive schedule as implemented by UKHSA.
Can I get it privately now?
Varicella vaccination has been available privately in the UK for years. Private travel clinics, some GP practices and a growing number of community pharmacies offer Varivax or Varilrix on a self-pay basis. Prices for a two-dose course are typically in the region of £130–£180 in total, varying by provider. A pharmacist administering the vaccine privately must be trained, the service must be operating under an appropriate PGD or private prescription, and parental consent is required.
What are the side effects?
Common side effects include pain or redness at the injection site, low-grade fever, and a mild varicella-like rash in a minority of children roughly 5–26 days post-vaccination. The vaccine-associated rash is usually sparse and self-limiting. Rare serious adverse events are listed in the Green Book.
Can a vaccinated child spread vaccine-strain virus?
Transmission of vaccine-strain VZV from a vaccinated child to a contact is rare but documented in the literature, usually in the presence of a vaccine-associated rash. The usual counter advice is for recently vaccinated children with a rash to avoid close contact with severely immunocompromised individuals until the rash resolves.
Does the vaccine affect the risk of shingles later in life?
Varicella and shingles are caused by the same virus — chickenpox being the primary infection, shingles the reactivation later. A long-standing concern raised in JCVI's earlier discussions was whether reducing childhood chickenpox could increase shingles incidence in middle-aged adults who no longer get periodic exposure to wild-type virus. Modelled evidence, and real-world data from countries with established varicella vaccination programmes (United States, Germany, Australia), has helped inform the current UK recommendation. The long-term interaction with the adult shingles vaccination programme continues to be monitored.
Is it safe for children with allergies?
Children with a known anaphylactic reaction to a previous dose or to a vaccine component (neomycin, gelatin in some formulations) should not receive the vaccine. Egg allergy is not a contraindication to varicella vaccine. The prescribing clinician should check the Green Book for contraindications and precautions.
Can the vaccine be given to immunocompromised children?
As a live vaccine, varicella is contraindicated in many forms of significant immunosuppression. There are specialist protocols for some well-controlled conditions — decisions are made by the paediatric team, not at the pharmacy counter.
What if my child has already had chickenpox?
Children with a documented history of chickenpox are considered immune and do not routinely require vaccination. In practice, documented history is often unreliable for very young children, and serology is rarely done. The Green Book guides clinical decisions in borderline cases.
Does the vaccine replace the need for hygiene and isolation during an outbreak?
No. Until vaccine coverage is high, pockets of susceptible children remain, and the usual public health measures around symptomatic cases continue to apply.
What community pharmacists are being asked to do
As the programme is implemented, community pharmacies have three realistic counter roles:
- Answer parent questions accurately. The FAQ above covers most of them.
- Signpost appropriately. NHS-eligible families to their GP or local commissioned service; self-paying families to a suitably credentialled private provider.
- Support the ongoing OTC advice for chickenpox. Until vaccine coverage is high, symptomatic cases will continue to present. Pharmacy First does not cover chickenpox-specific treatment, but counter self-care advice — paracetamol, avoiding ibuprofen, calamine for itch, hydration, symptomatic ocular hygiene — remains standard.
