Introduction
The rabies vaccine is the first requirement almost every destination demands. But what trips up the plan isn't the vaccine itself — it's the timing. Too early, too late, or vaccinated before the chip is in, and you start over. This guide from Convey lays out the three timing steps you can't get wrong, so you can plan backward from your travel date with accuracy.
The 3 timing steps you can't skip
Step 1: Microchip before the vaccine
The destination only counts a rabies vaccine given after the ISO microchip was implanted. If your pet was vaccinated before the chip was in, that vaccine doesn't count — you have to chip, then re-vaccinate (see our microchip article for more).
Step 2: Minimum age and following the vaccine schedule
Your pet must be at least 12 weeks old before getting a travel-purpose rabies vaccine, and it has to be administered according to the manufacturer's recommendations. The vaccine has to remain valid (not expired) throughout the trip.
Step 3: Confirm immunity with a blood test (Rabies Titer / RNATT)
Many destinations require a blood test for antibody level after vaccination, with the result reading ≥ 0.5 IU/mL to meet international standards. This is the single longest-running step in many timelines.
Timing by destination
Destinations vary widely on titer timing requirements. Here are the common cases.
| Destination | Titer required? | Wait after blood draw |
|---|---|---|
| UK (Thailand is "unlisted") | Yes | Draw ≥ 30 days after vaccine, then wait 3 more months |
| Australia (Thailand non-approved) | Yes | RNATT result valid 12 months; must wait ≥ 180 days before entry |
| Some relaxed destinations | Sometimes no | Per destination rules |
Golden rule from the Convey team: For destinations that require titer, always plan backward from the flight date. The wait after blood draw can be 3 to 6 months — start late and you miss the flight.
Why timing matters more than you'd think
- Drawing blood too early (before antibody levels rise) can result in a sub-standard reading — you'd need a booster and a redraw
- Drawing too late means the 3-month (UK) or 180-day (Australia) wait pushes the flight date further out
- If the vaccine expires mid-journey, your pet fails the criteria immediately — you have to time the booster carefully
