What about Seafarers? Are they given priority?

Although the UN’s IMO and other bodies moved with extraordinary and commendable speed to categorize mariners as Essential Workers who should be entitled to early access to testing and vaccine, not all nations have ratified that ruling. Lack of universal ratification may not obligate all the maritime nations to recognise mariners’ essential status. Even the countries that ratified seafarers as essential may not list them in their priority categories. It may be some time before we see availability of vaccine for large numbers of seafarers.
