The vaccination must be given after the microchip is inserted. The pet must be at least 12 weeks old before the vaccine is given and it must be given by an authorised veterinary practitioner. You must wait until the appropriate immunity has developed, as stated by the datasheet of the vaccination given, which must be at least 21 days after the primary vaccination is given, before you can bring the dog, cat or ferret to Ireland. If the datasheet of the vaccination used says that immunity is not present until day 30 after vaccination, then you must wait 30 days before travel and your vet should record the same in the EU pet passport (if used) and health certificate, before bringing the dog, cat or ferret to Ireland. A rabies vaccination with a 1 year or 3 year validity period is acceptable for entry into Ireland. Booster vaccinations only are exempt from the post vaccine waiting period, if there has been no break in coverage. If there has been a break in coverage, the next vaccination will be considered a primary vaccination, and the appropriate waiting period applies.
