Description
For sample children under 6 years old who have an immunization record and who have at least four DTP vaccines on their record, IMRDTPY4 reports the year when the person received his/her fourth DTP vaccine. DTP shots are sometimes called diphtheria-tetanus-pertussis shots, baby shots, or three-in-one-shots.
Users should combine IMRDTPY4 with IMRDTPDA4 and IMRDTPMO4, which report the day and month when the person received his/her fourth DTP vaccine.
Users are strongly encouraged to visit the Universe tab for more information on changes in the universe across surveyed years.
