AHC errors and the common rejection reasons VetForms watches for

There are two failure modes that VetForms flags:

• The microchip is recorded as read after the rabies vaccination date. Even if the chip was actually implanted earlier, the certificate fails because the documented read cannot prove identity at the moment of vaccination.
• The rabies vaccine is recorded as administered before the animal was identified by microchip. This invalidates the vaccination for travel purposes.

VetForms checks the dates in your draft and stops you signing a certificate where either of these would apply.

The rules are familiar but easy to miscount under time pressure:

• Day 0 is the day of vaccination. Travel cannot occur until at least 21 days have passed.
• For booster vaccinations given inside the manufacturer’s duration of immunity, no wait applies — but the booster date and the previous valid date must both reconcile.
• A primary vaccination administered after a lapse counts as a new primary, with the 21-day wait reset.

VetForms compares travel dates against the rabies record and flags any combination that would not be valid on the day of issue.

The Annex IV form is a bilingual document. VetForms handles the formatting that gets missed when the form is filled by hand:

• Destination-language text is generated alongside English.
• Strikethroughs and deletions are applied to the boxes that do not apply to the species or journey.
• Pages are numbered across all sheets, including the annexes.
• The OV’s APHA-issued UCN is placed in the correct field and matched against your loaded batches.

VetForms prompts for the sections that are commonly left blank or partially completed, including:

• Tapeworm treatment details for dogs travelling to listed countries.
• Owner signature and contact fields.
• OV details including SP number and stamp.
• Each animal’s identifying description.

These prompts run before generation, so the corrections happen once, not after you have already signed.

• VetForms is not APHA-approved or Defra-approved. APHA authorises OVs to issue certificates and allocates certificate numbers; VetForms is software you use to fill them in.
• VetForms does not guarantee border acceptance. Border officers make their own decisions on the day, and rules can change.
• VetForms does not eliminate rejection risk. It surfaces the most common reasons before you sign; it does not promise to catch every possible error.

APHA authorises the OV and issues certificate numbers. The OV signs the AHC on their own SP number and remains the certifying party. VetForms is a productivity aid that helps the OV complete the certificate accurately and quickly.
