Title: Use of SMS and Interactive Reminders to Improve Timely Immunization Coverage: A Randomized Controlled Trial
Brief Summary: Pakistan has one of the highest infant mortality rates in the world. One child in eleven dies before their fifth birthday. In part, this is due to the low coverage rate of routine childhood immunizations. Since Pakistan is a Low Middle Income Country (LMIC) it is essential that an immunization intervention be developed that is suitable for its socioeconomic setting. The tele-density of Pakistan exceeds 70% and the cost of SMS in Pakistan is very low. Moreover the use of SMS in the country has broadened beyond the conventional use of peer-peer chat to include social networking, SMS banking, delivery tracking, advertising, business, disaster management, and identity verification. This study will utilise this prevalence of mobile phones to assess whether simple and interactive sms reminders can serve to increase childhood immunization coverage and timeliness.

The pilot study will be carried out only in 2 EPI (Extended program on Immunization) centers at Korangi. The pilot will determine whether automated text messages produce increased immunization coverage in the reminder groups compared to the control group. 656 participants will be enrolled at Penta-1 and will be followed up until measles-2 vaccination. The results of proposed pilot will provide the basis for a large scale-up study in urban and rural settings in Pakistan.
