Vaccination Coverage in India: Progress, Gaps, and the Way Forward
India's Immunization Story
India's Universal Immunization Programme (UIP) is one of the largest public health programs in the world, targeting 26 million infants and 29 million pregnant women annually. Over the past decade, the program has made remarkable progress while facing persistent challenges.
Key Achievements
Mission Indradhanush
Launched in 2014, this initiative aimed to accelerate coverage of unvaccinated and partially vaccinated children. Through phased campaigns:
- Full immunization coverage increased from 62% to over 87% (NFHS-5)
- Over 40 million children vaccinated through special campaigns
- Focus on 554 high-priority districts with low coverage
New Vaccine Introduction
India has introduced several new vaccines in recent years:
- Rotavirus vaccine (2016) — now in over 20 states
- Inactivated Polio Vaccine (2016) — as part of polio eradication endgame
- Measles-Rubella vaccine (2017) — campaign reached over 340 million children
- Pneumococcal Conjugate Vaccine (2021) — phased introduction across states
Persistent Gaps
Geographic Disparities
Coverage varies significantly across states — from over 90% in Kerala and Tamil Nadu to under 70% in Uttar Pradesh and Rajasthan. Within states, rural and tribal areas consistently lag behind urban centers.
Missed Children
Despite progress, an estimated 2.7 million children in India remain unvaccinated or under-vaccinated. Common reasons include:
- Migration and mobile populations
- Vaccine hesitancy fueled by misinformation
- Access barriers in remote areas
- Opportunity misses during illness visits
Strategies for 100% Coverage
- Intensified microplanning: Village-level vaccination session planning with real-time tracking
- Community engagement: Involving ASHA workers and local leaders in awareness campaigns
- Digital tracking: The eVIN (Electronic Vaccine Intelligence Network) system for vaccine logistics
- Convergence: Coordinating with nutrition and health outreach programs
- Addressing hesitancy: Culturally appropriate communication strategies for specific communities
