The rabies vaccination and the 21 day wait
Your pet cannot enter the EU until 21 full days have passed after the first rabies vaccination. The vaccination cannot be given before your pet is 12 weeks old, and the microchip has to be in place first.
No blood test is required for a journey from the UK to Spain. The UK is a listed country, so the rabies antibody titration test that applies to some other origins does not apply here.
Counting the 21 days
The day of the vaccination does not count. Start counting from the following day, and your pet can travel on day 22.
Vaccinated on 1 March, your pet is clear to travel on 22 March. Not the 21st.
Some vaccines state a longer period before immunity. If the record from your vet shows a later date than 21 days, that date wins.
We have seen people lose a booking to that one day. If the dates are tight, send us the vaccination date and we will confirm the earliest travel date in writing before you commit to a ferry.
The wait applies to the first vaccination. If your pet already has unbroken rabies cover and gets a booster before the previous one expires, there is no new waiting period and you can travel the same day.
Keeping the cover unbroken
This is the part worth planning around. As long as each booster is given before the previous vaccination expires, your pet stays continuously covered and never has to sit out another 21 days.
Let it lapse by a single day and the next vaccination counts as a first vaccination all over again, with a fresh 21 day wait attached. For a family that drives to Spain twice a year, letting the booster slip in a quiet winter is the mistake that ruins the following summer.
Put the expiry date in your calendar with a month of warning. Booster intervals vary by product, from one year to three, so use the date printed in your pet record rather than assuming.
What the record has to show
At the certificate appointment the official veterinarian needs to see proof of the vaccination, not just your word for it. The record has to show the date, the product, the batch number and the signature or stamp of the vet, and the microchip number it belongs to.
If your pet was vaccinated at a different practice, bring the original record with you. A verbal history is not enough, and a certificate cannot be issued from a gap.
A certified copy of the vaccination record is normally attached to the certificate itself, stamped page by page. That is normal and it is not the vet being awkward.
Age limits for puppies and kittens
A rabies vaccination cannot be given before 12 weeks of age. With the 21 day wait added, the earliest a puppy or kitten can travel is roughly 15 weeks.
FAQ
- How long after a rabies vaccination can my pet travel?
- 21 full days. The day of the vaccination does not count, so a pet vaccinated on 1 March can travel on 22 March.
- Does my pet need a rabies blood test to go to Spain?
- No. The UK is a listed country, so no titration test is required for travel to an EU country.
- Do I have to wait 21 days after a booster?
- No, as long as the booster was given before the previous vaccination expired. If the cover lapsed, the new jab counts as a first vaccination and the 21 day wait starts again.
- What is the minimum age for a rabies vaccination?
- 12 weeks. Add the 21 day wait and the earliest travel age is about 15 weeks.
- My pet was vaccinated at a different vet. Does that matter?
- No, but bring the original record. The official veterinarian issuing the certificate has to see documented proof of the date, product, batch number and the microchip it relates to.
