The guidance presented in the TOGD and the Manual (Doc 10152) is under constant revision
as new scientific evidence becomes available. ICAO continues to closely monitor the scientific and
technological developments, in particular those related to vaccination and their impact on travel by air. In
this regard, ICAO has been working with other international organizations, especially the WHO, to align
efforts and is ready to incorporate each new development in its guidance.
As the vaccination is being rolled out globally, increasing number of passengers will be
vaccinated in the near future. This will result in a growing uncertainty with different epidemiological
realities from one State to another. It is intended that further iterations of the CART guidance will give
consideration to the following near- and long-term issues:
ICAO will convene a High-Level Conference on COVID-19 (HLCC 2021) in October 2021.
Aiming at creating a path to post COVID-19 recovery, the Conference will consider short- and long-term
implications engendered by the crisis, proposals for States to use in tackling safety, operational and
economic challenges, and streamlined policy responses to post-pandemic state of aviation. It will also
provide an opportunity to share experiences among States and industry, and strengthen and demonstrate
multilateral cooperation, States’ individual and collective engagements, as well as efforts and political
commitments to building sustainable, resilient aviation.
