Almost 1 million American children have not been properly immunized, so they risk serious illness.
Many adults also are at risk.
Proper vaccination could have prevented one of the largest outbreaks of measles, which occurred in Dallas about 10 years ago and killed 12 people. Texas has a mandatory childhood vaccination schedule for children through age 18. But until a child reaches school age, parents and caregivers must work with their medical providers to ensure proper immunization. Many families may have overlooked some of the new recommendations and the new inoculations available both for children and adults. Because of heightened area risks, Hepatitis A vaccination is now recommended for Dallas residents.
