INTERNATIONAL AIRLINE MEDICAL ASSOCIATION

.

Greetings again MCG,

The medical evidence document has been updated again, and can be accessed from the same link here: https://www.iata.org/globalassets/iata/programs/covid/restart/covid-public-health-meausures-evidence-doc.pdf

One of the areas which has been updated relates to vaccination preventing transmission. 

It will continue to be updated, but new versions will be at the same above link (complete with spelling mistake).
