Vaccines are medications that help the body fight diseases. The vaccination’s goal is to train the immune system to recognize and destroy harmful substances. There are prevention vaccines and treatment vaccines.
They are made from very small amounts of weak or dead germs that can cause illnesses —viruses, bacteria, or toxins. The immune system is then activated and develops cell that are ready to fight the disease if your body comes in contact with it.
Different countries may require different immunizations, based on what illnesses are prevalent in their region. The Centers for Disease Control and Prevention (CDC) has a tool that allows you to search for the vaccines you’ll need based on the country where you’re traveling.
While some vaccinations are required, others are a personal choice and your decision to get them is based on your risk tolerance. Some diseases, however, are too dangerous. If a vaccine is developed, if it’s not made mandatory, you probably should get it anyway.
