Summary

This trial tests whether a brief online game can help Canadian adults better identify COVID-19 vaccine misinformation. Participants judge true/false statements and get instant feedback in a game-like format, compared to reading the same information as a blog post or doing nothing. The study measures knowledge accuracy immediately and after one month, along with vaccination intention and confidence.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
A gamified misinformation refutation quiz
What this could lead to
If effective, this could offer a scalable digital tool to counter health misinformation and increase vaccine uptake.
What could go wrong
The effect may be short-lived or not translate into actual vaccination behavior; the trial relies on self-reported outcomes.
