Whether or not you need a vaccine to go on a cruise depends on the cruise line's individual requirements and the destinations you'll be visiting. However, many cruise lines strongly recommend that passengers be fully vaccinated against COVID-19 before boarding. This is because cruise ships are often in close quarters, which can increase the risk of spreading illness.
There are several benefits to getting vaccinated before going on a cruise. First, it can help protect you from getting sick, which can ruin your vacation. Second, it can help protect others on the ship, especially those who are more vulnerable to illness. Third, it can give you peace of mind knowing that you're doing your part to prevent the spread of disease.
