Travel Vaccination Timeline Planner

Sequence pre-travel vaccines by calculating how many days you need between doses plus a safety buffer before departure.

Time remaining before you leave.
How many doses the series needs (count boosters too).
Smallest allowed gap between doses for the vaccine.
Optional. Leave blank for a 10-day buffer after the last dose.

Examples

  • Departure in 9 weeks, 2-dose series, 28-day gap, 10-day buffer ⇒ Result: Start within the next 25 days
  • Departure in 6 weeks, 3-dose series, 21-day gap, 14-day buffer ⇒ Result: Start 5 days before today

FAQ

How do I add blood test checks?

Add extra buffer days equal to the lab turnaround required for proof-of-immunity testing before departure.

What if doses can be accelerated?

Enter the accelerated interval if the manufacturer allows it. Some vaccines have rapid schedules specifically for travellers.

Can I plan overlapping series?

Run the calculator for each vaccine series separately, then compare the start-by dates to coordinate appointments.

Additional Information

  • Output tells you how soon to schedule the first dose to complete the series before departure.
  • Include country entry requirements or lab test windows by increasing the buffer days.
  • If you finish early, maintain immunity documentation for border checks and carry physical records.
  • Consult travel medicine clinics for vaccines with complex schedules such as rabies pre-exposure or Japanese encephalitis.
