Complete guide to Mission Indradhanush covering target diseases, phases (IMI 1.0-4.0), coverage achievements, and difference from Universal Immunisation Programme.

Mission Indradhanush (MI) is a flagship immunisation initiative of the Government of India launched in December 2014 by the Ministry of Health and Family Welfare. Named after the rainbow (Indradhanush in Hindi), the mission aims to achieve full immunisation coverage for all children under two years of age and pregnant women by targeting areas with low vaccination rates. It represents a significant acceleration of India's longstanding Universal Immunisation Programme (UIP) and is a frequently asked topic in UPSC Prelims and Mains.

Background — The Universal Immunisation Programme

Mission Indradhanush — Immunisation Drive, Phases & UPSC Relevance — visual guide 1

India's Universal Immunisation Programme (UIP) was launched in 1985 as one of the largest public health programmes in the world. It provides free vaccination against life-threatening diseases to approximately 2.67 crore newborns and 2.9 crore pregnant women annually.

Despite the UIP's scale, India's full immunisation coverage had plateaued at around 65% by 2014, with significant inter-state and inter-district variations. Pockets of low coverage — particularly in urban slums, tribal areas, and hard-to-reach regions — meant that nearly 5 lakh children died annually from vaccine-preventable diseases.

Mission Indradhanush was launched to bridge this gap and accelerate progress toward universal coverage.

Target Diseases

Mission Indradhanush initially targeted seven diseases, with additional antigens added over time:

#DiseaseVaccine
1DiphtheriaDPT / Pentavalent
2Pertussis (Whooping Cough)DPT / Pentavalent
3TetanusDPT / TT
4PolioOPV / IPV
5TuberculosisBCG
6MeaslesMR (Measles-Rubella)
7Hepatitis BPentavalent
8Haemophilus influenzae type b (Hib)Pentavalent (added)
9Japanese Encephalitis (JE)JE vaccine (in endemic districts)
10Rotavirus diarrhoeaRotavirus vaccine (phased introduction)
11Pneumococcal diseasePCV (Pneumococcal Conjugate Vaccine)
12RubellaMR vaccine (added with Measles-Rubella campaign)

The name "Indradhanush" (rainbow with seven colours) originally referred to the seven diseases; subsequent expansions increased the count beyond seven.

Key Achievements

Mission Indradhanush vs Universal Immunisation Programme

FeatureUniversal Immunisation Programme (UIP)Mission Indradhanush
Launched1985December 2014
NatureRoutine, ongoing programmeTime-bound, campaign-mode acceleration
Coverage approachAll children/pregnant women through routine immunisation at health facilitiesSpecifically targets low-coverage pockets through special drives
TargetAll eligible beneficiariesUnvaccinated and partially vaccinated children and pregnant women
FrequencyContinuous (routine immunisation days)Intensive rounds in selected districts
MonitoringRoutine health system monitoringSpecial task forces, inter-ministerial committees, real-time tracking
RelationshipBase programmeAccelerator/supplement to UIP

Important: Mission Indradhanush does not replace the UIP. It supplements it by conducting targeted, intensive drives in areas where routine immunisation has failed to reach all beneficiaries.

Implementation Strategy

The mission uses a four-pronged strategy:

  1. Meticulous planning — District-level micro-plans identifying session sites, mobilisers, and cold chain logistics.
  2. Effective communication — Community engagement through ASHA workers, Anganwadi workers, and mass media campaigns.
  3. Intensive monitoring — Real-time data tracking; special task forces at national, state, and district levels.
  4. Accountability framework — Monthly review meetings; name-based tracking of every beneficiary.
