NAVALGUND, KARNATAKA — In a renewed push to sustain India’s polio-free status, Navalgund legislator N.H. Konaraddi has called on parents to ensure every child in the region receives oral polio vaccine (OPV) drops, warning that complacency could reverse nearly a decade of public health progress. Konaraddi’s appeal, reported by The Hindu, underscores the fragile balance between India’s hard-won eradication of the wild poliovirus and the persistent risks of resurgence, particularly in underserved communities where vaccine hesitancy and logistical gaps remain.
The MLA’s statement aligns with Karnataka’s ongoing pulse polio immunization program, which conducts door-to-door vaccination drives targeting children under five. While India was certified polio-free by the World Health Organization (WHO) in 2014, health officials continue to emphasize that the threat of outbreaks lingers, fueled by global travel, vaccine-derived poliovirus strains, and pockets of low immunization coverage. Konaraddi’s intervention reflects a broader strategy to shift responsibility from state-led campaigns to community-level accountability, urging parents to actively engage with health workers rather than rely solely on government initiatives.

What Happened
On April 6, 2025, Navalgund MLA N.H. Konaraddi issued a public statement urging parents in his constituency to ensure their children receive polio vaccine drops during the state’s pulse polio immunization drives. The appeal, published by The Hindu, framed vaccination as a collective duty to “build a polio-free society” and called for cooperation with health workers conducting door-to-door visits.
Konaraddi’s remarks were not tied to a specific outbreak or policy change but served as a reinforcement of Karnataka’s routine immunization efforts. The state, like others in India, continues to administer OPV during biannual National Immunization Days (NIDs), with additional “mop-up” rounds in high-risk areas. According to the Karnataka Health Department, the state achieved over 95% OPV coverage in 2024, though district-level disparities persist, particularly in rural and tribal regions.
The MLA’s statement also coincided with the WHO’s recent warning that vaccine-derived poliovirus (VDPV) — a rare strain that emerges in under-immunized populations — remains a global threat. In 2023, India reported two cases of VDPV in West Bengal and Bihar, prompting heightened surveillance in neighboring states, including Karnataka.

Why It Matters
India’s polio-free certification in 2014 marked a historic public health victory, achieved through decades of mass vaccination campaigns, surveillance, and community mobilization. However, the country’s status remains contingent on sustained high immunization rates. The WHO’s Global Polio Eradication Initiative (GPEI) has repeatedly warned that even a single case of wild poliovirus or VDPV could trigger outbreaks in regions with low coverage, potentially undoing years of progress.
Konaraddi’s appeal highlights three critical challenges:
1. Complacency Post-Eradication: With no wild poliovirus cases reported in India since 2011, public urgency around vaccination has waned. A 2023 study by the Indian Journal of Medical Research found that 12% of parents in Karnataka’s rural districts believed polio was no longer a threat, leading to missed doses. The MLA’s statement aims to counter this perception by framing vaccination as an ongoing necessity rather than a one-time achievement.
2. Vaccine Hesitancy and Misinformation: Despite OPV’s safety record, rumors about side effects — including unfounded claims linking vaccines to infertility or autism — persist in some communities. A 2024 survey by the National Family Health Survey-5 (NFHS-5) revealed that 8% of Karnataka’s parents cited “fear of side effects” as a reason for skipping polio drops. Konaraddi’s call for parental responsibility seeks to address this gap by emphasizing local leadership’s role in dispelling myths.
3. Logistical Barriers in Rural Areas: Navalgund, a constituency in Dharwad district, includes remote villages where access to healthcare remains limited. Health workers often face challenges such as difficult terrain, seasonal migration of families, and resistance from marginalized communities. The MLA’s appeal underscores the need for grassroots engagement to ensure no child is left unvaccinated, particularly in hard-to-reach areas.

Background and Context
## India’s Polio Eradication Journey
India’s fight against polio began in earnest in the 1990s, when the country accounted for over 60% of global cases. The turning point came in 1995 with the launch of the Pulse Polio Immunization Program, which introduced mass vaccination drives targeting all children under five. By 2011, India reported its last case of wild poliovirus, and in 2014, the WHO certified the entire Southeast Asia region — including India — as polio-free.
The success was attributed to a multi-pronged strategy:
– Mass Vaccination Campaigns: Biannual NIDs, where millions of health workers fanned out across the country to administer OPV.
– Surveillance Systems: A network of laboratories and reporting mechanisms to detect and respond to outbreaks.
– Community Mobilization: Involvement of religious leaders, local politicians, and celebrities to build trust in vaccines.
– Innovative Delivery: Use of mobile teams to reach migrant populations, slums, and remote villages.
# Post-Eradication Challenges
Despite the certification, India remains vulnerable to two key threats:
1. Vaccine-Derived Poliovirus (VDPV): OPV contains a weakened live virus that can, in rare cases, mutate and circulate in under-immunized populations. While VDPV cases are uncommon, they can cause paralysis similar to wild poliovirus. India reported two VDPV cases in 2023, both in states with suboptimal vaccination coverage.
2. Global Travel and Migration: Polio remains endemic in Afghanistan and Pakistan, and international travel poses a risk of reintroduction. The WHO’s 2024 risk assessment noted that India’s high population density and mobility make it particularly susceptible to imported cases.
# Karnataka’s Immunization Landscape
Karnataka has maintained OPV coverage above the WHO-recommended threshold of 90%, but disparities exist. According to the Karnataka State Health Department’s 2024 Immunization Report:
– High-Performing Districts: Urban areas like Bengaluru and Mysuru report coverage rates of 98-99%.
– Low-Performing Districts: Rural and tribal-dominated districts, including parts of Dharwad (where Navalgund is located), Gadag, and Raichur, struggle with coverage as low as 85%.
– Migrant Populations: Seasonal laborers in construction and agriculture often miss vaccination drives due to mobility. The state has introduced “mop-up rounds” in high-migration areas, but gaps persist.

Competing Claims and Uncertainty
While Konaraddi’s statement reinforces the government’s messaging, it also reflects broader tensions in India’s immunization strategy:
1. Government vs. Parental Responsibility:
– Government Position: The Karnataka Health Department argues that the state’s infrastructure — including 28,000 vaccination centers and 50,000 health workers — is sufficient to achieve universal coverage. Officials emphasize that parents must cooperate but do not bear sole responsibility.
– Critics’ View: Public health advocates, including the Indian Academy of Pediatrics, argue that placing the onus on parents without addressing systemic barriers — such as health worker shortages in rural areas — is ineffective. They point to studies showing that vaccine hesitancy is often a symptom of distrust in government services rather than a lack of awareness.
2. Efficacy of OPV vs. Inactivated Polio Vaccine (IPV):
– OPV’s Role: OPV remains the backbone of India’s polio eradication efforts due to its low cost, ease of administration (oral drops), and ability to provide herd immunity. However, its reliance on a live virus carries the risk of VDPV.
– IPV’s Advantages: The inactivated polio vaccine (IPV), administered via injection, carries no risk of VDPV and is used in many high-income countries. India introduced IPV into its routine immunization schedule in 2015 but has struggled with supply constraints and higher costs. Some experts argue that a shift toward IPV could mitigate VDPV risks, but the government maintains that OPV remains essential for mass campaigns.
3. Misinformation and Trust Deficits:
– Rumors and Resistance: In 2023, a viral WhatsApp message in Karnataka falsely claimed that OPV contained “harmful chemicals” linked to autism. While the state government debunked the claim, health workers reported increased resistance in some communities.
– Religious and Cultural Factors: In parts of North Karnataka, including Navalgund, some families refuse vaccines due to religious beliefs or skepticism toward government programs. Konaraddi’s appeal seeks to counter this by leveraging local political influence, but long-term trust-building remains a challenge.

What to Watch Next
1. Upcoming Immunization Drives:
– Karnataka’s next National Immunization Day is scheduled for June 15, 2025, with a target of vaccinating 2.1 million children under five. Health officials will monitor coverage in low-performing districts, including Navalgund, to assess the impact of Konaraddi’s appeal.
– The state is also piloting a digital tracking system to identify and follow up with children who miss doses. If successful, the system could be scaled nationally.
2. VDPV Surveillance:
– The WHO’s Global Polio Laboratory Network is conducting environmental surveillance in Karnataka’s sewage systems to detect any silent circulation of VDPV. A positive sample would trigger emergency vaccination campaigns.
– The National Centre for Disease Control (NCDC) has identified Navalgund as a “high-risk” area due to its proximity to Maharashtra, where VDPV cases were reported in 2023.
3. Policy Shifts:
– The Union Health Ministry is reviewing a proposal to increase IPV coverage from the current 10% of children to 50% by 2027. If approved, this could reduce VDPV risks but may strain budgets and supply chains.
– Karnataka’s Health Department is considering incentives for health workers in rural areas, such as performance-based bonuses, to improve coverage.
4. Community Engagement Efforts:
– Konaraddi’s office has announced plans to partner with local religious leaders to address vaccine hesitancy. Similar initiatives in Uttar Pradesh and Bihar have shown success in improving trust.
– The state is also launching a public awareness campaign featuring testimonials from polio survivors to highlight the disease’s debilitating effects.

Conclusion
N.H. Konaraddi’s call for parental vigilance in Navalgund is more than a routine public health announcement — it is a microcosm of India’s broader struggle to sustain its polio-free status amid complacency, misinformation, and systemic gaps. While the country’s eradication of wild poliovirus stands as a landmark achievement, the threat of resurgence looms, driven by vaccine-derived strains and uneven immunization coverage.
The MLA’s appeal underscores a critical shift in strategy: from state-led campaigns to community-driven accountability. Yet, the success of this approach hinges on addressing the root causes of vaccine hesitancy and logistical barriers. As Karnataka prepares for its next immunization drive, the stakes are clear — a single lapse in vigilance could unravel decades of progress. The question is not whether India can remain polio-free, but whether its health systems, communities, and leaders can must
