Do you need booster to cruise is a question that many travelers have. A booster is a dose of vaccine that is given after the initial series of vaccinations to maintain immunity. In the case of cruising, a booster is typically required for tetanus, diphtheria, and pertussis (Tdap), and measles, mumps, and rubella (MMR).
Getting a booster is important because it helps to protect you from these diseases, which can be serious and even life-threatening. Boosters are especially important for people who are traveling to areas where these diseases are common. In addition, some cruise lines require passengers to have up-to-date vaccinations, including boosters, before they can board.
