My thinking is that when the major cruise lines get the green light to resume business, future passengers should be required to provide proof of that year's influenza vaccine and also be required to be tested for COVID-19 even after things settle down. The question is will the general public ever regain their confidence in cruise ships again. St. Maarten ports-of-call, IMO, are essential down the road because they work to introduce new visitors to the island. Let's hope they get this right when the time arrives.
