Rajasthan Chief Minister Bhajanlal Sharma launched a large-scale Sub-National Pulse Polio Campaign on November 23, 2025, aiming to vaccinate over 1.08 crore children under five across the state. This initiative is part of ongoing efforts to protect children from polio, a potentially fatal and disabling disease, with the administration of oral polio vaccine drops both at fixed booths and through door-to-door campaigns. The state has set up 58,823 polio booths, along with 6,741 transit teams and 8,989 mobile teams to ensure comprehensive coverage, emphasizing the importance of vaccination in securing the future of the next generation.
Key Campaign Details and Objectives
The campaign intends to reach every child under five in Rajasthan through a combination of static booths, mobile teams, and transit teams stationed at busy public places such as railway stations and bus stands. Chief Minister Sharma personally administered polio drops at his residence to inaugurate the campaign and urged parents to ensure their children receive the two recommended oral polio vaccine drops. The campaign slogan, “Do Boond Har Baar, Polio Par Jeet Rahe Barkarar,” highlights the protective efficacy of even two drops of the oral vaccine.
Oral Polio Vaccine and Its Efficacy
The oral polio vaccine (OPV) is a critical tool in global polio eradication efforts. Studies estimate that two doses of OPV or a combination of oral and inactivated vaccines provide around 90% or higher protection against paralytic polio, with effectiveness increasing with additional doses. The recommended vaccination schedule typically includes multiple doses to confer robust immunity from poliovirus infection. OPV’s oral administration facilitates mass immunization campaigns in resource-limited settings and helps interrupt transmission of the virus via fecal-oral routes.
Public Health Significance and Context
India was declared polio-free in 2014 after decades of intense vaccination campaigns, which dramatically reduced cases from tens of thousands in the 1980s to zero. However, continuous vigilance remains imperative due to reported polio cases in neighboring countries and risks of virus importation. Rajasthan’s campaign contributes to sustaining herd immunity, preventing any resurgence of the virus. Effective vaccination coverage exceeds 95% to maintain population immunity and protect children from lifelong paralysis caused by poliovirus.
Challenges and Considerations
While OPV is highly effective, limitations include rare cases of vaccine-associated paralytic poliomyelitis. Nonetheless, these cases are exceedingly rare compared to the disease burden prevented by vaccination. Ensuring full coverage in remote and underserved populations remains a challenge, addressed by mobile and transit vaccination teams. Continuous monitoring and community engagement are essential to overcoming vaccine hesitancy and logistical hurdles, ensuring no child is left unvaccinated during this campaign.
Expert Perspectives
Health officials emphasize that this vaccination drive is a critical public health intervention that safeguards children from a preventable disease known for causing irreversible paralysis. Experts advocate for parental cooperation and community support, as the risk of poliovirus resurgence persists if immunization gaps occur. The campaign’s extensive reach and mobilization of health workers demonstrate Rajasthan’s commitment to polio eradication and child health protection.
