Adult Vaccination

Vaccines are developed using either dead strains of a disease, weakened strains, or strains of a different disease that can confer some immunity. As adults we may need a booster of the vaccine we received years ago to remain immunized. Travelers may receive vaccines either as a condition of entry to a country, or on recommendation of health officials. Generally there is little or no reaction to a vaccine, but in some cases the vaccine may cause either a rare allergic reaction or a temporary, mild illness. A few vaccines are not safe for pregnant women, so be certain to let the health care provider know if you are or may be pregnant. Learn more about adult vaccinations from our experts.
