Assuming you want to be vaccinated for COVID-19, how long might it be before you can get one? I do not guarantee the accuracy of this but the New York Times has an interactive page that will give you an estimate.
Before you click on it — which you will do, despite what I'm about to point out here — remember that the prioritizing may change and there may be logistic problems in getting supplies of vaccine to where they can be administered. Also, there are different polls out there about how many people are even interested in getting vaccinated. The Pew Research Center poll says 60% will get it but whatever the number is, it'll change as people see how easy it is, how many of their friends do or don't do it, if there are reports of unexpected side effects, etc.
Also, what if I want the Moderna vaccine and the only ones available are Pfizer's and AstraZeneca's? And how will this work with the vaccines that require two doses a month apart? And can my health insurance plan do anything to move me up on the list?
So now that I've told you how worthless I think the Times estimator is, I'll tell you that it told me that in Los Angeles County, 703,500 people are ahead of me in line to get the vaccine. That might not be such a long wait if 40% of the folks in my town refuse to be vaccinated. It might go even quicker if I'm successful in my campaign to get comic book writers classified as essential workers.
