**3. Conclusion**

Regulations for safety and effectiveness of vaccines in the uncontrolled, real world context should be strengthened in developing countries. Perhaps the set of ethical considerations when fully operational in developed countries will be applied to them also. The World Health Assembly established 3 milestones towards eradication of measles. They intend to increase routine coverage with MCV1 by more than 90% nationally and more than 80% in every district; reduce and maintain annual measles incidence to less than 5 cases per million; and reduce estimated measles mortality by more than 95%. Based on current trends of measles vaccination coverage and incidence, and report of the strategic review, the WHO Strategic Advisory Group of Experts on Immunization (SAGE) concluded that the 2015 global milestones and measles elimination goals were not achieved because immunization coverage gaps exist. SAGE recommended focus on improving immunization and surveillance systems to ensure gains made thus far in measles control can be sustained. The situation in developing countries requires serious attention and strict compliance by stakeholders to ensure goals are met.
