Summary
Vaccinations are among the most effective measures of preventive medicine. Especially in infants and young children, they can prevent potentially harmful diseases and hospitalization. Almost no one currently living in the US has seen vaccine-preventable diseases first-hand because their frequency has been dramatically decreased by vaccination. However, they persist worldwide and vaccination programs are essential to prevent future outbreaks of diseases like pertussis, mumps, and measles. In the US, immunization guidelines are published and updated every year by the Centers for Disease Control and Prevention (CDC) and Advisory Committee on Immunization Practices (ACIP). The schedule is designed to protect children when they are most vulnerable and individuals at high-risk before they are exposed to possibly life-threatening diseases.
Furthermore, international travelers are at risk of exposure to vaccine-preventable diseases depending on the region visited and the activities planned. Travelers should therefore seek advice about potential immunizations before departure. At a pretravel consultation, the traveler's prior immunizations, health conditions, and likely exposure to diseases while traveling should be taken into account. Information on travel vaccinations may be found on the CDC and the WHO websites.
