Free Vaccine Queue Calculator for Wales

Understanding the Wales COVID‑19 Vaccine Queue Estimator

This tool estimates your position in the COVID‑19 vaccine queue for Wales and predicts when you are likely to receive your first dose. By combining the UK government’s official priority criteria with the planned vaccination pace in Wales, the calculator gives you a personalised picture of how many people are ahead of you and how long the wait might be. The data used in the current version was last refreshed in August 2021, so the numbers reflect the situation at that time.

Why a Vaccine Queue Calculator for Wales?

COVID‑19 has caused widespread disruption and tragic loss of life, with Wales recording over 5,300 fatalities linked to the pandemic. Vaccination is the most powerful tool to bring the outbreak under control. The first approved vaccine was administered in Wales on 8 December 2020, marking the start of the mass immunisation effort. However, with limited initial supply, a clear and fair order of priority is essential. This tool helps you understand where you stand in that order based on your age, occupation, and health status.

The Priority Framework

The prioritisation scheme adopted by the Welsh Government follows the UK’s nine‑point list for Phase 1, with additional age‑bands for Phase 2. The aim is to protect those most at risk of severe illness and death, as well as frontline workers who face the highest exposure.

Phase 1 (Nine Priority Groups)

Priority	Eligible Groups
1	Residents in older‑adult care homes and their carers
2	Everyone aged 80+ and frontline health & social care workers
3	Everyone aged 75–79
4	Everyone aged 70–74 and clinically extremely vulnerable individuals
5	Everyone aged 65–69
6	Individuals aged 16–64 with underlying health conditions that increase COVID‑19 risk; unpaid carers who receive Carer’s Allowance or are the main carer for an elderly or disabled person
7	Everyone aged 60–64
8	Everyone aged 55–59
9	Everyone aged 50–54

Phase 2 (Age‑Based Rollout)

After Phase 1, the remaining adult population is divided by age to simplify and speed up distribution:

• Group 10: 40–49 years
• Group 11: 30–39 years
• Group 12: 18–29 years

Who Qualifies as Clinically Extremely Vulnerable?

Individuals in this category are those at very high risk of serious COVID‑19 outcomes. The UK Government’s shielding list includes:

• Recipients of solid organ transplants
• People undergoing active chemotherapy for cancer
• Patients with lung cancer receiving radical radiotherapy
• Those with blood or bone marrow cancers (leukemia, lymphoma, myeloma) at any treatment stage
• People having immunotherapy or other continuing antibody treatments for cancer
• Patients receiving targeted cancer treatments that affect the immune system (e.g., protein kinase inhibitors, PARP inhibitors)
• Individuals who have had a bone marrow or stem cell transplant in the past six months or are still on immunosuppressive therapy
• People with severe respiratory conditions such as cystic fibrosis, severe asthma, or severe COPD
• Those with rare diseases that greatly increase infection risk (e.g., severe combined immunodeficiency, homozygous sickle cell disease)
• Individuals on immunosuppression therapy that significantly raises infection risk
• People with spleen‑related conditions (e.g., splenectomy)
• Adults with Down’s syndrome
• Patients on dialysis or with stage 5 chronic kidney disease
• Pregnant women with significant heart disease (congenital or acquired)
• Others classed as clinically extremely vulnerable based on clinical judgement

If you received a letter advising you to shield during previous lockdowns, you are automatically considered clinically extremely vulnerable.

Underlying Health Conditions That Increase Risk

Even if you are not classed as clinically extremely vulnerable, having one of the following conditions places you in priority group 6:

• Chronic respiratory disease (COPD, cystic fibrosis, severe asthma)
• Chronic heart or vascular disease
• Chronic kidney disease
• Chronic liver disease
• Chronic neurological condition (including epilepsy)
• Down’s syndrome
• Severe or profound learning disability (on the GP learning disability register)
• Diabetes
• Solid organ, bone marrow, or stem cell transplant recipient
• Specific cancers (leukemia, lymphoma, myeloma, etc.)
• Previous stroke or transient ischaemic attack (TIA)
• Neurological or muscle‑wasting disease
• Immunosuppression due to disease (e.g., HIV) or treatment
• Asplenia or splenic dysfunction (e.g., sickle cell disease, removed spleen)
• Morbid obesity (BMI of 40 or higher)
• Severe mental illness

Your GP can confirm whether your condition qualifies you for earlier vaccination.

Pregnancy and Breastfeeding

Current guidance (as of the tool’s last update) allows pregnant women and those planning pregnancy within the next three months to receive the Pfizer‑BioNTech or Moderna vaccine. This recommendation is based on data from over 90,000 pregnant women vaccinated with mRNA vaccines in the USA, with no safety concerns raised. For breastfeeding women, both the Pfizer‑BioNTech and AstraZeneca vaccines may be offered because non‑live vaccines carry no known risk; however, limited safety data specific to COVID‑19 vaccines should be discussed before consent.

Children

Routine vaccination of individuals under 16 years is not currently recommended, except in rare cases where the risk of exposure and severe outcomes is very high. A full risk‑benefit assessment is required before vaccinating a child. This position may change as more trial data become available.

How the Calculator Works

Your Inputs

You provide the following details:

• Age (16–120): older age generally means a higher priority.
• Care home status: whether you live or work in an older‑adult care home.
• Pregnancy: whether you are currently pregnant or planning pregnancy in the next three months.
• Frontline health or social care worker: e.g., nurse, doctor, care assistant.
• Clinically extremely vulnerable: yes if you fall under the shielding criteria.
• Underlying health condition: yes if you have one of the listed conditions.

Output

The calculator estimates:

• Minimum and maximum number of people ahead of you in the queue.
• Time until your first dose and time until full protection (two doses), based on the vaccination rate.

Vaccination Rate and Uptake

By default, the tool uses the Welsh Government’s planned rate of 150,000 doses per week, aiming for 740,000 doses by mid‑February 2021. You can change this to:

• The average rate from the last seven days, or
• A custom value of your own.

The uptake rate (the proportion of people who accept the vaccine when offered) is set to 69% by default – the uptake level for the flu vaccine among people aged 64+ in the previous year. You may adjust this if newer data suggest a different figure.

Important Disclaimer

This calculator follows the official UK priority list and assumes the average vaccination rate. It does not account for individual exemptions or local variations in rollout. Always refer to updated guidance from the Welsh Government and your GP for the most current information.

Using the Tool Effectively

To get the most accurate estimate, enter your current age, answer the health and occupation questions honestly, and, if you wish, adjust the rollout parameters to match the latest news. The tool will then show your estimated queue position and wait time, helping you plan ahead for your vaccination.

Additional Considerations

• The priority list and population size estimates were updated several times during 2021 (e.g., Phase 2 groups were added in March 2021, and the second‑dose interval was shortened from 12 weeks to 8 weeks for groups 9 and below in May 2021).
• The calculator considers the proportion of first vs. second doses administered recently to account for fluctuations in the rollout pace.

By understanding your place in the queue, you can better prepare for your turn and continue following public health measures in the meantime.
