The COVID-NMA initiative
A living mapping and living systematic review of Covid-19 trials
COVID-NMA is an international research initiative supported by the WHO and Cochrane.
We provide a living mapping of COVID-19 trials. We are also conducting living evidence synthesis on vaccines, preventive interventions and treatments for COVID-19 to assist decision makers.
For 2023, COVID-NMA revised its protocol and reduced its scope.
- For the living mapping, we continue to update and include all COVID-19 vaccine trials only.
- For the living evidence synthesis, we continue to update only COVID-19 vaccines boosters.
See the description of our model here and our living review protocol here.
