After several destructive cyclones stalled vaccination progress in Mozambique, a major recovery effort is underway. In late March, the latest “Big Catch-up” campaign reached 432,474 children who had missed their routine immunizations. JSI is proud to support the Ministry of Health in training teams and managing vaccine supplies to ensure every child is protected, regardless of the challenges.

JSI Supports the “Big Catch-up” to Close Immunization Gaps in Mozambique - JSI Research & Training Institute, Inc. JSI is committed to improving vaccination coverage and protecting the health of children in Mozambique.

Reaching zero-dose and under-immunized children requires understanding not only whether an intervention worked, but how and why it did.

The JSI-led Zero-Dose Learning Hub has created a Theory-Based Evaluation Toolkit to help governments and partners design and evaluate immunization strategies using clear, explicit theories of change. Drawing on country learning from Bangladesh, Mali, Nigeria, and Uganda, the toolkit supports real-time learning, adaptation, and stronger decision-making.

From “Did it work?” to “Why did it work?” How theory-based evaluation strengthens immunisation Asking whether a programme worked is no longer enough. To reach zero-dose and under-immunised children, we also need to understand why a programme worked.
