After years of sleuthing, Australian researchers believe they have cracked the cause of lethal blood clots caused in rare cases by AstraZeneca’s COVID vaccine – and how to beat the problem.

The clots occurred in two to three out of every 100,000 people who received the vaccine.

A global research collaboration of scientists from McMaster University (Canada), Flinders University (Australia) and ...
