Context:
- Despite improved vaccination coverage globally, India still has one of the highest absolute numbers of zero-dose children, pointing to persistent socio-economic disparities and challenges in reaching marginalized communities.
Key Highlights:
- Between 1980 and 2023, global vaccine coverage for six major diseases doubled.
- Zero-dose children (those not receiving the first DTP dose) globally dropped by 75%, yet India had 1.44 million such children in 2023.
- India ranks second globally in the number of zero-dose children; part of a group of eight countries with over 50% of the global burden.
- India had 23 million births in 2023, the highest globally; the zero-dose rate stood at 6.2%.
- The number of zero-dose children fell from 2.7 million in 2021 to 1.44 million in 2023, yet remains above the pre-COVID level of 1.4 million in 2019.
- High concentrations of zero-dose children were found in Uttar Pradesh, Bihar, Maharashtra, Rajasthan, Madhya Pradesh, Gujarat, and several Northeastern States.
- Prevalence remains high among the poor, less-educated mothers, Scheduled Tribes, and Muslim communities.
Detailed Insights:
- Zero-dose children serve as a proxy indicator of vaccine access inequalities and health system reach.
- India’s large birth cohort magnifies the absolute burden, even when percentage-wise prevalence is relatively low.
- COVID-19 disrupted immunisation services, causing a surge in zero-dose children in 2021.
- Improvements have occurred, with gender, caste, and rural-urban disparities narrowing over the years.
- Persisting pockets of unvaccinated children are linked to poverty, low maternal education, marginalized communities, and vaccine hesitancy, particularly in Muslim households and tribal/urban slum areas.
- India risks missing WHO’s IA2030 target of halving the 2019 zero-dose numbers by 2030 unless focused interventions are scaled up.
- The issue demands localized outreach, community mobilisation, education, and targeted policy measures in high-burden areas.
Key Concepts Involved:
- Zero-dose children: are those children who have not received even a single dose of any routine vaccine, typically measured as infants who have not received the first dose of the DTP vaccine.
- DTP vaccine: A combination vaccine that protects against three life-threatening bacterial diseases — diphtheria, tetanus, and pertussis.
- WHO’s Immunization Agenda 2030 (IA2030): A global strategy aiming to halve the number of zero-dose children from 2019 baseline levels by 2030, promoting equity in vaccination access.
Mains Mock Question:
Q. The persistence of zero-dose children in India reflects deeper socio-economic inequalities and public health gaps. Critically evaluate policy measures needed to achieve equitable immunisation coverage in India by 2030.
