Why there is a twenty-one day wait after the rabies jab

A pet cannot enter the European Union until twenty-one days have passed since its rabies vaccination. The clock starts the day after the injection, and the day of the vaccination itself does not count.

What the wait is for

It is the time the vaccine needs to produce immunity. Before that the animal is recorded as vaccinated but is not yet protected, and the rule exists because the consequence of getting it wrong is a disease that is effectively untreatable once symptoms appear.

When the clock restarts

• A first vaccination always starts a twenty-one day wait
• A booster given before the previous one expired does not: the animal stays covered throughout
• A booster given even one day late counts as a first vaccination, and the wait starts again

That last line is the one to watch. A booster a fortnight overdue is a three-week delay to your move, and the only way to find out is to read the date on the record.

Planning around it

Work backwards from the date you want your pet to arrive. Take off twenty-one days for the wait, then a few more for the certificate appointment, then a fortnight of slack for the appointment you cannot get at the practice that is fully booked. Two months is comfortable. Three weeks is not.
