As of 17 April, passengers who are fully vaccinated and have the documents to confirm this, are no longer required to complete mandatory hotel quarantine on arrival in Ireland. Dependents, including children, will also be exempted from the requirement to complete mandatory hotel quarantine in this instance. Please note that the four European Medicines Agency approved vaccines currently accepted have specific definitions for when a person would be considered fully vaccinated.
These definitions are available at: https://www.gov.ie/en/publication/3b8e1-mandatory-hotel-quarantine-your-questions-answered/#exemptions-from-mandatory-hotel-quarantine
The Government continues to evaluate wider policy on international travel as informed by the epidemiological situation and public health advice.
