I agree it should be a joint campaign with both sides of the island vaccinating their people. A quick search shows that poorer Caribbean islands will get the jab first through COVAX/ PAHO. The distribution to other islands have been funded and in place months ago. The French are actually not so in favor of getting the jab and Pres. Macron has recovered from COVID-19.

I hope other airlines don’t use this promotion... Jab n Go
