COVID-19 Data Explorer - Tracking COVID-19 Vaccine Roll-Out in Countries with Humanitarian Crises Format The COVID-19 Data Explorer brings together data to show the impact of the COVID-19 pandemic – the virus and its secondary impact – for countries affected by humanitarian or refugee crises. With thanks to the contribution of many IASC partners, the COVID-19 Data Explorer now showcases 50 datasets from more than 25 sources. Two new features has been added to the COVID-19 Data Explorer. In response to the action point at the IASC Principals Meeting in July, OCHA is now producing a Monthly Highlights that pulls out the key analysis from the data on the Explorer and complemented by other information. The Monthly Highlights are a quick way to stay up to date on the latest trends of how the pandemic is impacting GHO countries. The latest Monthly Highlights can be found here.
