Study: Six-in-One Vaccine Promises Smarter Immunization for India

Introducing a hexavalent vaccine into India's Universal Immunisation Programme could streamline childhood immunisation efforts. This combined vaccine offers protection against six diseases—diphtheria, tetanus, pertussis, Hepatitis B, Haemophilus influenzae type b, and polio—in a single dose.

This consolidation promises substantial benefits, including fewer injections for infants, easing the burden on frontline health workers, and reducing cold-chain storage demands. The study, involving the Union Health Ministry and global health organizations, found that caregiver preference leans towards fewer injections during vaccination visits.

Researchers highlighted that the vaccine's price is the primary factor in programme costs. However, a significant price reduction could make the operational savings outweigh the acquisition costs. The study explored various implementation scenarios, assessing costs from both government and household perspectives.

Published in *Human Vaccines & Immunotherapeutics*, the findings underscore the potential for improved convenience and efficiency for families and healthcare systems. Susmita Chatterjee noted that while upfront costs are higher, the efficiencies gained provide strong economic evidence for policy discussions on strengthening India's immunisation programme.
