Wow, fraudulent vaccine paperwork to overcome a sample of 350,000... That is a stretch, to put it mildly. Maybe, you were joking.
No one said the 350k were all Qatar people, or 50-percent guest workers....so I have no idea about ‘trust’. I can show in various countries that vaccination rate is 5-to-10 percent. Did the Qatar guest-worker crowd all get vax’ed-up prior to arrive or arrange for some ‘stamp’? It would help this case to say only Qatar citizens were in the 350k group.
