Mission Indradhanush is an Indian government health initiative launched in 2014 with the goal of reaching all unvaccinated and partially vaccinated children and pregnant women by 2020. It aims to increase routine immunization coverage in the country from 65% to 90%. Key objectives include ensuring high coverage of vaccines for preventable diseases like diphtheria, tetanus, tuberculosis, polio, hepatitis B, and measles. The program focuses on conducting immunization drives and generating demand through communication. It also aims to strengthen coordination between stakeholders to effectively implement vaccination programs. Multiple phases have been conducted across states targeting millions of beneficiaries through organized vaccination sessions.
