IATA
The International Air Transport Association (IATA) have urged governments to make data-driven decisions to manage the risks of COVID-19 when reopening borders to international travel.

Strategies without quarantine measures can enable international travel to restart with a low risk of introduction of COVID-19 to the travel destination. IATA point to many sources of evidence to support this, including the European Centre for Disease Control and Prevention (ECDC), which issued interim guidance on the benefits of full vaccination stating that “the likelihood of an infected vaccinated person transmitting the disease is currently assessed to be very low to low.”
