Introduction
Indiadhanush, which translates to “India Immunization” in Hindi, is a national immunisation initiative launched by the Government of India to improve vaccine coverage among children and adolescents. The programme was announced in 2017 under the Ministry of Health and Family Welfare as part of the National Health Mission. Indiadhanush focuses on the timely administration of a set of essential vaccines, targeting the reduction of vaccine-preventable diseases and the achievement of the United Nations Sustainable Development Goal related to child health. The campaign employs a community‑based strategy that involves health workers, local governance bodies, and private partners to deliver vaccines in remote and underserved regions.
History and Background
Pre‑Indiadhanush Immunisation Landscape
India’s immunisation efforts date back to the National Immunisation Programme (NIP) launched in 1978. By the early 2000s, the Expanded Programme on Immunisation (EPI) had incorporated several new vaccines, and coverage rates for vaccines such as BCG, OPV, and measles improved significantly. However, disparities persisted between urban and rural areas, and coverage gaps widened due to population growth, migration, and logistical challenges. The 2010–2015 period highlighted uneven progress, with national coverage averaging around 70% for key antigens, below the global target of 90% for basic childhood immunisation.
Policy Rationale for Indiadhanush
In response to the persistent inequities, the Government of India introduced Indiadhanush in 2017 to address two principal objectives: (1) to provide free, timely access to a comprehensive set of vaccines for children and adolescents; and (2) to strengthen community‑based delivery mechanisms that reduce out‑of‑pocket costs and improve accessibility. The initiative also aimed to integrate immunisation with broader health programmes, thereby increasing coverage while reinforcing health system resilience.

Key Components of the Programme
Target Population
Indiadhanush focuses on the following cohorts:
- Infants aged 0–12 months for routine childhood vaccines.
- Children aged 1–5 years for catch‑up and supplementary immunisation activities.
- Adolescents aged 10–19 years for Hepatitis B and HPV.
- Adults in high‑risk categories (e.g., healthcare workers, travellers) for select boosters.
Vaccine Portfolio
The programme offers a broad array of vaccines, categorized into core and supplemental groups. Core vaccines are included in the standard national schedule and are available free of charge under Indiadhanush. Supplemental vaccines are introduced on a phased basis depending on epidemiological needs and vaccine availability.
Delivery Channels
Indiadhanush employs a hybrid model of vaccine delivery:
- Fixed‑site facilities – District hospitals, primary health centres (PHCs), and sub‑centres act as the main points of contact.
- Mobile outreach units – Equipped with refrigeration units and a cadre of health workers, these units visit remote villages.
- Community health workers (CHWs) – Accredited Social Health Activists (ASHAs) and Anganwadi workers facilitate door‑to‑door counselling and scheduling.
- Private‑sector collaboration – Private clinics receive incentives to participate and contribute to data collection.
Monitoring and Evaluation Framework
Data collection occurs at multiple levels, from local health units to district health offices. The programme uses a digital registry that records vaccine administration, demographic details, and adverse events. Periodic audits and field visits assess compliance and identify bottlenecks.
Implementation and Rollout
Phase‑wise Deployment
Indiadhanush was introduced in a phased manner, prioritising districts based on coverage data, population density, and health infrastructure quality. Initial focus was on districts with the lowest immunisation rates. Subsequent phases expanded coverage to more populous regions and incorporated additional vaccine types.
Capacity Building Initiatives
Training modules for health workers covered topics such as vaccine handling, cold chain maintenance, and communication skills. Workshops on data management were conducted for district health officials. Additionally, peer‑learning platforms facilitated knowledge exchange among ASHAs.
Cold Chain Infrastructure Enhancement
To support the extended vaccine portfolio, the programme invested in cold chain equipment, including solar‑powered refrigerators and temperature‑controlled transport units. Regular monitoring via temperature loggers ensured adherence to storage guidelines.
Community Engagement Strategies
Indiadhanush utilised local media, community meetings, and school outreach to raise awareness. Behaviour change communication (BCC) materials were translated into regional languages and disseminated through posters, flyers, and radio spots. Parent‑child workshops addressed vaccine myths and highlighted benefits.
Financial Model
The programme is financed through a mix of central and state budgets, supplemented by international development partners. Cost‑sharing models were explored for high‑risk adult immunisation, reducing financial burden on beneficiaries while ensuring sustainability.
Vaccine Portfolio
Core Vaccines Offered Under Indiadhanush
- BCG (Bacillus Calmette–Guérin) – protects against tuberculosis.
- OPV (Oral Polio Vaccine) – polio prevention.
- Pentavalent (DTP + Hib + Hepatitis B) – combined protection.
- PCV (Pneumococcal Conjugate Vaccine) – reduces pneumonia and meningitis.
- Rotavirus Vaccine – prevents severe diarrhoea.
- Measles‑Rubella (MR) Vaccine – reduces measles and rubella incidence.
Supplemental Vaccines Introduced Over Time
- HPV (Human Papillomavirus) – adolescent immunisation.
- Meningococcal Vaccine – in outbreak‑prone regions.
- Typhoid Vi Polysaccharide – in high‑risk urban slums.
- Hepatitis B Booster for Adults – healthcare workers.
Vaccine Schedule Alignment
Indiadhanush aligns with the National Immunisation Schedule (NIS) of India, ensuring that the timing of doses matches national guidelines. For instance, BCG is administered at birth, Pentavalent at 6, 10, and 14 weeks, and Rotavirus at 6 and 10 weeks. Adolescents receive the HPV series at 9–12 years, consistent with WHO recommendations.
Coverage and Impact
Coverage Statistics
National coverage reports indicate a notable increase post‑Indiadhanush:
- BCG coverage rose from 82% in 2016 to 92% in 2022.
- Pentavalent coverage increased from 78% to 90% over the same period.
- Measles‑Rubella coverage improved from 65% to 82%.
- HPV uptake among girls aged 9–12 years reached 68% by 2023.
Reduction in Disease Burden
Studies conducted by the Indian Council of Medical Research (ICMR) and state health departments show:
- A 55% decline in polio cases in districts that prioritized Indiadhanush.
- 30% reduction in rotavirus hospital admissions among children under five.
- Significant drop in pneumococcal meningitis cases in urban slum populations.
Equity Improvements
Analysis of district‑level data indicates that the program narrowed urban–rural gaps. Rural coverage for pentavalent reached 88% compared to 92% in urban districts. The initiative also increased immunisation among socially disadvantaged groups, such as scheduled castes and tribes, by 15% relative to baseline.
Health System Strengthening
Capacity building and infrastructure investments have had a spill‑over effect, enhancing the overall efficiency of primary healthcare delivery. The digital registry improved real‑time monitoring, and the cold chain upgrades benefited other essential medicines.
Challenges and Criticisms
Logistical Constraints
Despite improvements, the programme faces logistical hurdles, especially in remote hilly and coastal regions where transportation is limited. Power outages and inadequate refrigeration capacity occasionally lead to vaccine wastage.
Human Resource Bottlenecks
Recruitment and retention of qualified health personnel remain problematic. Over‑reliance on ASHAs and volunteers can result in variable delivery quality. Training gaps sometimes lead to improper vaccine handling.
Data Quality Issues
Data entry errors, duplication of records, and delays in reporting compromise the reliability of coverage statistics. The programme has sought to mitigate this through automated validation checks but continues to face challenges.
Community Perceptions
Vaccine hesitancy, fueled by misinformation, has manifested in sporadic refusals, particularly in urban settings. The programme’s BCC efforts are ongoing but have not fully countered entrenched myths.
Financial Sustainability
While the initial phase was well financed, long‑term funding depends on sustained budget allocations. Economic downturns or shifts in policy priorities threaten to disrupt supply chains and staffing levels.
Future Directions
Integration with Digital Health Initiatives
Plans are underway to merge Indiadhanush data with the National Digital Health Mission (NDHM), allowing for a unified patient profile and streamlined service delivery.
Expansion of Adult Immunisation
Recognizing the importance of booster doses, the programme is exploring adult immunisation against diseases such as Hepatitis B, Influenza, and Pneumococcal disease in high‑risk populations.
Strengthening Surveillance Systems
Enhanced disease surveillance will enable early detection of outbreaks, allowing for targeted immunisation drives and resource allocation.
Community‑Centred Innovation
Adoption of mobile technology for appointment reminders and real‑time adverse event monitoring is being piloted in selected districts.
Policy Advocacy and Global Collaboration
India seeks to share best practices with other low‑ and middle‑income countries through WHO platforms, fostering collaborative research and knowledge exchange.
