25% of the US vaccinated against Covid when?
The Covid-19 vaccination rollout in the United States has been much slower than anticipated, with fewer than 7 million people having received a shot by Jan. 7, 2021, far short of the goal of 20 million by the end of December 2020.
However, new attempts are being made in streamlining the vaccination process. This may speed up the rate that shots are delivered, or it may do very little. So:
When will 25% of the US population be vaccinated against Covid-19?
Resolves positive when 82.5 million people in the US have completed their course of vaccination (so, after both shots for multi-shot treatments) for a vaccine with efficacy >70%. Resolution via credible media reports.
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
