American adoption of the seasonal flu vaccine

Influenza is an endemic viral disease that infects hundreds of millions each year. Most are only mildly ill and out of work for a week, but some hundreds of thousands die, mostly the elderly and immunocompromised. Vaccination is at present the most effective means to combat it.

In the United States, the CDC's Advisory Committee on Immunization Practices recommends annual flu vaccination for everyone over 6 months without specific contraindications. Despite this, uptake is mediocre, at only 45.3% of the 18-and-over population for the 2018-2019 season. Decades of ad campaigns and public health interventions have struggled to move the needle. One reason may be that the lowest-complying group, young adults with no preexisting conditions, may not understand how their own vaccination protects more vulnerable groups.

What value will the CDC's FluVaxView website report for flu vaccination coverage among adults ≥18 years for the 2020–2021 flu season?

The CDC's FluVaxView website usually publishes results in the fall after the relevant season (fall 2021 here). If no results have been published by 2021-12-31, this resolves ambiguous unless Metaculus has found a suitable replacement.


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.

Community Stats

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.
