Been watching this also. We will be traveling in April and my 12 year old son is fully vaxxed. His school is involved with a local university that is tracking the virus, working on vaccines, so they offer weekly testing at the school, which we opted in for. That being said, I'm just planning on getting my wife and I tested prior so the whole family has results to just cover our butts right before we go. Given the ever changing climate, I am just gonna err on the side of better to have and not need than need and not have.
