About the Vaccine Queue Calculator for Ireland
This calculator estimates how long you may wait for your turn in a vaccine rollout queue using a basic throughput (queueing) model: how many people are ahead of you, divided by how many people the program finishes vaccinating each day. It is an independent planning tool, not a lookup of official HSE appointment data - it will not tell you your actual place in any real national queue, only what a queue of the size and speed you enter would imply.
How the wait time is calculated
The model works in two steps. First, it converts the national daily dose count into people finished per day by dividing by the number of doses your course requires: people vaccinated per day = daily dose rate / doses per person. Second, it divides the people ahead of you by that daily throughput to get the estimated number of days until your turn: estimated wait (days) = people ahead of you / people vaccinated per day. Adding that many days to today's date gives the estimated turn date.
Reading your queue position
The queue position result shows what share of the remaining, still-waiting population is ahead of you: people ahead of you divided by total people still waiting, expressed as a percentage. A lower percentage means fewer people are in front of you relative to the whole remaining queue, independent of how fast the program is running that week.
When to consult official sources
For your actual appointment status, use the HSE's official vaccination information channels or contact your GP or pharmacy directly - this tool cannot access real scheduling systems. Treat the output here as a rough planning estimate built from the numbers you supply, not a guarantee of any specific date.
