America has ~330 million people. Let's assume the 18.7 Million was just in the month of january..not 100% acurate, but not 100% inaccurate. That gives us a timeline of more than 1 year at current rate to vaccinate the entire US. Even vaccinating 70% the population will take roughly a year at current pace. Puts things in some perspective.
I realized in December or early January that due to the insane mismanagement it's going to ruin this summer too, and it'll likely be Q3 of this year before travel is really safe or reasonable again.
