Sorry...sometimes reading several pages of posts leave me more confused than when I started, so I apologize in advance for my basic question. My wife and I (US citizens) will be in Paris and plan on taking a flight to OPO. We are vaxed and double boosted with our last booster in April. We plan on getting an antigen test in Paris within 24 hours of our flight to OPO. Uh...is that it? Anything else we need?
