Sad to see it go, CTP has been an essential resource for colleagues and I over the last year.<p>Post March, the Covid data space is going to change drastically (frankly, it already has) with this news as well as SafeGraph ending its Covid data consortium. Only a matter of time before JHU CSSE and the NYTimes wind down their efforts.<p>The reality is two fold and unfortunate. Case data is seemingly less pertinent, but vaccine data is less fruitful. It’s going to be at least a few quarters before vaccination is widely available and Covid is going to become endemic. Thus, both metrics are vitally important to how we traverse the next year.<p>It has been amazing to see widespread data efforts around Covid, and the entire field of epidemiology could benefit from collaborations of this scale. So thank you folks at the Covid Tracking Project and anyone else who has contributed to similar data efforts in the last year.
