Microbe-Literacy Germ-Watching Workshops for Hygiene and Vaccine Acceptance in Sargodha, Pakistan

This cluster randomized controlled trial evaluated whether a single microscope-based "germ-watching" workshop, delivered by Lady Health Workers (LHWs) to mothers and female caregivers of children under three years, improves hygiene practices, vaccination attitudes and intentions, routine immunization, and trust in LHWs. Twelve Union Councils in Sargodha District, Pakistan, were allocated 1:1 to the intervention or routine services, with outcomes measured by structured baseline and endline surveys and facility immunization records.

About this study

In intervention clusters, LHWs used portable microscopes (>=400x) to show caregivers the microorganisms present in their own household water and food samples during a single 120-minute workshop for 25-30 participants, linking observed microbes to hygiene and vaccine-preventable disease. Control clusters received routine LHW services and standard national health messaging. Allocation used restricted, covariate-constrained randomization at the Union Council level; outcome data entry and analysis were blinded to allocation. Analyses accounted for clustering.

Treatment and study plan

Microbe-literacy germ-watching workshop

Behavioral

Group demonstration (25-30 participants) using portable microscopes to visualize microorganisms in participants' own environmental samples, linked to hygiene and immunization messages

Primary outcomes

  1. Proportion of caregivers/children reporting always washing hands (self-reported)

    Time frame: Baseline and 4 months (endline, immediately after the intervention period)

    Percentage of caregivers (and their children) reporting they "always" wash hands with soap / before eating, from a structured interviewer-administered survey item, compared between arms.

  2. Third-dose oral polio vaccine (OPV3) coverage (facility records)

    Time frame: 4 months (endline)

    Percentage of index children with a documented third dose of oral polio vaccine, ascertained from facility immunization records, compared between arms.

  3. Proportion with self-reported completion of the age-appropriate immunization schedule

    Time frame: Baseline and 4 months (endline)

    Percentage of caregivers reporting the index child had received all age-appropriate vaccinations (structured survey item), compared between arms.

Secondary outcomes

  1. Proportion reporting high trust in Lady Health Workers

    Time frame: Baseline and 4 months (endline)

    Percentage of caregivers responding "yes, a lot" to a single-item survey question on trust in Lady Health Workers for vaccine information, compared between arms.

  2. Proportion aware that germs cause infectious disease

    Time frame: Baseline and 4 months (endline)

    Percentage of caregivers identifying germs (rather than, e.g., "bad weather") as the cause of infectious disease on a survey item, compared between arms.

  3. Proportion perceiving vaccines as safe

    Time frame: Baseline and 4 months (endline)

    Percentage of caregivers responding "yes, safe" to a survey item on perceived vaccine safety, compared between arms.

  4. Proportion intending to vaccinate ("very likely")

    Time frame: Baseline and 4 months (endline)

    Percentage of caregivers responding "very likely" to a survey item on intention to vaccinate the child in future, compared between arms.

  5. Proportion willing to recommend vaccination to others

    Time frame: Baseline and 4 months (endline)

    Percentage of caregivers responding "yes" to a survey item on willingness to recommend vaccination to other mothers, compared between arms.
