India Could Switch to Six-in-One Vaccine for 26M Babies

India could soon make vaccination day much easier for millions of babies and their families.

A major new study shows that introducing a six-in-one vaccine into India's national immunization program would reduce the number of shots children need while protecting them against the same diseases. The research was conducted by India's Health Ministry working with the George Institute for Global Health India, the Gates Foundation, Gavi, and other health organizations.

Right now, 26 million Indian babies get vaccinated each year through multiple injections at each doctor visit. The new hexavalent vaccine would protect against diphtheria, tetanus, whooping cough, Hepatitis B, Haemophilus influenzae type b, and polio in just one shot.

The study, published in the peer-reviewed journal Human Vaccines & Immunotherapeutics, looked at both the costs and benefits of making the switch. Researchers found that if the vaccine price drops by 50 percent based on current purchasing trends in India, the savings from simpler operations would outweigh the cost of buying the new vaccine.

Parents and healthcare workers would see immediate benefits. Fewer injections mean less stress for babies and caregivers who currently spend significant time at multiple vaccination appointments. Frontline health workers would have lighter workloads, and the program would need less cold storage space for vaccines.

The research team studied two possible approaches: replacing current vaccines during the primary immunization schedule, or also replacing the booster shot. They calculated costs from every angle, including the vaccine itself, syringes, storage, healthcare worker time, and the time parents spend at appointments.

The Ripple Effect

The benefits extend far beyond convenience. When vaccination becomes simpler, more families are likely to complete the full schedule on time. Previous research shows that caregivers strongly prefer fewer injectable vaccines at each visit, which could improve overall immunization rates.

Healthcare systems in countries with limited resources face constant pressure. Every efficiency gain means workers can serve more children and families can access care more easily. Cold chain storage is expensive and limited in many areas, so needing less space for vaccines frees up resources for other health priorities.

Susmita Chatterjee from the George Institute for Global Health India explained that while the vaccine costs more upfront, it creates important efficiencies across the entire system. The economic evidence could help shape future policy decisions about strengthening India's immunization program.

The findings come at a crucial time as India works to improve healthcare access for its vast population. Making vaccination simpler and more convenient could help ensure more children receive complete protection against preventable diseases.
