Who is surprised that the federal government fell far short of its promise to vaccinate 20 million people by the end of 2020? I am not, really. There are many factors, including the reluctance of health-care workers to get vaccinated when their turns are up (I think that those who don't want the vaccine now should be free not to take it but go to the back of the line and be accountable for their decision, but that's a topic for another day).
