Pandemic propels global effort to study rare vaccine side effects

From Science.org:

Scientists in more than 20 countries, on every continent save Antarctica, have started to gather data for the largest ever vaccine safety project. Members of the effort, called the Global Vaccine Data Network (GVDN), fruitlessly sought funding after conceiving the project more than 10 years ago. But the mass vaccinations during the COVID-19 pandemic breathed new life into the project. With the ability to draw on data from more than 250 million people, the network will investigate rare complications linked to COVID-19 vaccines in hopes of improving prediction, treatment, and potentially prevention of these side effects.
