The problem
Intervention: Rotavirus immunisation using approved paediatric rotavirus vaccines
Who it was tested with: Young children in Russia, particularly those under 3 years of age; studied across regions with varying immunisation coverage.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Local observational studies confirm the favourable safety profile of rotavirus vaccines and demonstrate notable effectiveness of vaccination. In the regions with high immunisation coverage, the overall morbidity has declined dramatically in vaccinated children compared to unvaccinated children." These observational studies measured outcomes in vaccinated and unvaccinated populations, representing a comparison design without randomisation.
The review does not provide specific quantitative data on morbidity reductions, does not specify sample sizes or follow-up periods of the observational studies, and does not detail potential confounding factors in the comparisons between vaccinated and unvaccinated groups.
