Both the French and Dutch side governments on the island might want to consider an incentive program for the residents for COVID vaccinations. Given the percentage of residents on the island that live below the poverty level if some kind of modest monetary incentive program could be offered it could quickly boost up vaccination rates. Although an incentive for a potentially life-saving vaccine shouldn't be needed, the economy of St. Martin has taken some substantial hits from Irma back in 2017 and COVID strangling tourism in 2020. Such incentive programs have helped vaccination rates in some U.S. states, so there's no reason to think it wouldn't work on SXM.
