The problem
Intervention: SARS-CoV-2 vaccination at different coverage levels and with varying assumptions about vaccine effectiveness waning
Who it was tested with: Australian children aged 6 months to 11 years.
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.
"A non-dynamic model using age-specific PCC rates, in accordance with the WHO definition of LC and the National Academies of Sciences, Engineering, and Medicine (NASEM) definition of PCC, was applied to estimate the burden of LC in children during 2021-2023 and to evaluate the impact of vaccination under different coverage and vaccine effectiveness (VE) scenarios." The study projects vaccination impact on Long COVID prevalence through mathematical modelling of different coverage and vaccine effectiveness scenarios, representing a pre-post comparison approach applied to population-level estimates rather than individual-level data.
Model-based study with outcomes dependent on assumptions about vaccine effectiveness waning and coverage scenarios. No direct clinical trial data or real-world observational comparison of vaccinated versus unvaccinated children's outcomes.
