COVID-19 vaccinations in Bhutan - Mix-and-Match to Boosters: An experience.
Article in Vaccine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Bhutan - a landlocked least developed country in the Himalayas - vaccinated 94% of its adults with the first dose of COVID-19 vaccine in March-April 2021, 90.2% with second dose in July 2021, and 89.1% with booster (third) dose by March 2022. The country used COVISHIELD (Oxford-Astrazeneca) vaccine for the first dose but decided to pursue a heterologous prime-boost strategy ("mix-and-match") for the second dose using Moderna's mRNA vaccine for adults. Bhutan rapidly rolled out Pfizer and Moderna vaccines for 12 to 17-year-olds through a school-based vaccination strategy followed by booster doses: 78.6% of adolescents aged 12-17 years were vaccinated with the first dose by August 2021, 92.8% with second dose by November 2021, and 79.7% with booster (third) dose by March 2022. More than 97% of children aged 5 to 11 years have received Pfizer's Comirnaty vaccine for their first dose. Bhutan is steadily vaccinating its population and might soon become one of the few least developed countries to achieve herd immunity-level vaccination coverage with more than 80% of its population fully vaccinated.
