I'd be careful to understand what is built into that model. It gets cited a lot, but I think few understand that it is based on continuing strict social distancing indefinitely, until an effective vaccine is deployed and widely administered.
In other words, the IHME model isn't inherently wrong- it just makes an assumption that our politicians are going to act solely based on public health. And that's just not going to happen. When the stay at home orders come down, infection and hospitalization rates may well jump back up steeply.
