Imagine being able to go to the movies, send your kid to school or travel to see your relatives, without fear. Imagine being able to leave your mask at home. Youyang Gu, a data scientist whose model has proved the most accurate forecaster of COVID deaths, predicts we will reach herd immunity (or "normality," as his team now calls it) by June/July. We are not in the midst of a dark long winter. Indeed, progress may require continued mask-wearing and social-distancing for the next few months.
The model is named after a person and is named for 2 years.
