Hypothesis
Correcting common vaccine misconceptions with a correction endorsed by a group of medical experts would raise COVID-19 vaccination intention and actual uptake among UK residents.
What failed
The pre-registered experiment found the intervention did not change participants' attitudes or behaviour towards COVID-19 vaccines during the 2021 vaccination campaign, contrary to a similar study with Italian residents.
Broken assumption
Expert endorsement of a correction shifts vaccine attitudes and uptake, as it appeared to in another country.
Why
The report discusses possible reasons for the null without settling on one.
