Parents with children two years of age and younger are the target of a new advertising campaign from the Texas Department of Health. The campaign will be financed with about $1.5 million in federal funds. Parents will see billboard, radio, television, and print ads in both English and Spanish that urge them to get their children vaccinated against measles, mumps, polio, and other life-threatening diseases. The advertising campaign hopes to improve upon the 71 percent vaccination rate in Texas for children between the ages of 19 months and 35 months, according to the National Immunization Survey for 2002.
