People may wonder, "If the chance of getting the diseases is so low, why do I need the vaccine?" It is true that vaccination has enabled us to reduce measles, and most other vaccine-preventable diseases, to very low levels in the United States; however, measles is still very common -- even epidemic -- in other parts of the world. Visitors to our country, and U.S. travelers returning from other countries, can unknowingly bring this disease into the United States, and if we are not protected by vaccinations, it will quickly spread, causing an epidemic here. Measles is very contagious.
People should receive the MMR vaccine to protect themselves and their children. Even if you think the chance of getting measles is small, the disease still exists, and it can still infect anyone who is not protected.
