Well…. I am no expert on this as it changes all the time and I haven’t been to Ethiopia since before this Covid began. All I can say is that when our previous team went to Kenya a couple months back, they were not needed and the airlines / European governments only cared about negative tests within 72 hours. I got the vaccine in the hopes that travel would be easier, but it seems thus far that has not been the case. They seem still want negative tests everywhere you go. The rest of my family has not so…. yeah. regardless. I would have no qualms trying to travel with someone who didn’t want to get the vaccine unless we were certain it was required at some point. I don’t really care either way.
