In both countries, as of September 2020, fewer people would 'definitely' take a COVID-19 vaccine than is likely required for herd immunity.
“Here we show that in both countries-as of September 2020-fewer people would 'definitely' take a vaccine than is likely required for herd immunity”
From Measuring the impact of COVID-19 vaccine misinformation on vaccination intent in the UK and USA (2021) · cites this paper as [15]
The paper’s main text gives a formula for the minimum population immunity needed to halt spread, and Table 1 estimates thresholds for countries using data as of 13 March 2020. It does not report September 2020 vaccine willingness, whether people would ‘definitely’ take a vaccine, or a comparison between willingness and those thresholds in the two countries. (LLM, conf=0.88)
Experimental — accuracy not yet measuredA novel COVID-19 vaccine will need to be accepted by at least 55% of the population to provide herd immunity, with estimates reaching as high as 85% depending on country and infection rate.
“It is estimated that a novel COVID-19 vaccine will need to be accepted by at least 55% of the population to provide herd immunity, with estimates reaching as high as 85% depending on country and infection rate 15,16 .”
From Measuring the impact of COVID-19 vaccine misinformation on vaccination intent in the UK and USA (2021) · cites this paper as [15]
In the main text (page unavailable), the paper defines a critical level of population immunity that can be acquired through vaccination or infection. Table 1 reports country-specific thresholds, including 85.0% for Bahrain. It does not estimate vaccine acceptance, and the passages in our copy do not establish a 55% minimum; acceptance cannot be equated with immunity without accounting for vaccine effectiveness.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
