Project Incubator Program
Pharmacoepidemiology has largely been concerned with quantification of uncommon harms from medications. Estimating effectiveness is more challenging, because of potentially greater confounding and selection biases.Â
Most of the information on Covid-19 vaccine effectiveness we now rely on comes from ‘real world’ studies. As of September 2022, an international database contains details of over 300 effectiveness studies conducted in over 35 countries over approximately 18 months. In the field of pharmaco-epidemiology this is a unique database on the derivation of effectiveness estimates from routinely collected data. These studies have used a variety of different types of data and analytical methods, and results were generally strongly positive in terms of vaccine effectiveness.Â
We plan a scoping review of these studies to learn how the research has evolved throughout the pandemic in terms of questions, data, cohort definition, analysis, and techniques to minimise bias when estimating effectiveness. The review findings will be used to guide present and future vaccine effectiveness studies and will help guide real-world effectiveness studies of other medicines being evaluated in our CRE.

How have research questions, data sources, designs, and analytical methods used in evaluating post-licensing Covid-19 vaccine effectiveness (mortality reduction) studies evolved over the course of the pandemic?
Data will be leveraged from the data compiled in the .
Developing agreed standards for conduct of real-world effectiveness studies (vaccines and medicines) in Australia. This will be relevant to the planning of epidemic responses in future. Â
The results will be of value in the interpretation of contemporary studies of vaccine effectiveness and will have broader relevance to the conduct of pharmaco-epidemiological studies and methods training in the CRE and in pharmacoepidemiology in general.Â
