Developing a Latin American Delphi Consensus on Vaccination for Respiratory Diseases in Older Adults.
Article in Annals of geriatric medicine and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRespiratory infections significantly impact older adults in Latin America, highlighting the need for regionally adapted consensus-based vaccination recommendations to guide preventive strategies. This study aimed to develop a consensus among Latin American experts on vaccination against respiratory diseases in older adults in the region, including influenza, Streptococcus pneumoniae pneumonia, coronavirus disease 2019 (COVID-19), respiratory syncytial virus (RSV), and pertussis.
methodsA two-round Delphi methodology was employed, involving 35 specialists from various medical fields. A rapid evidence review was conducted using scientific databases and clinical practice guideline repositories. Participants evaluated each recommendation on a 1-to-5 scale; recommendations with 80% acceptance (score of 4 or higher) were approved.
resultsThe consensus resulted in recommendations for administering Tdap (tetanus, diphtheria, and pertussis) boosters every 10 years for pertussis and annual influenza vaccination in adults aged 65 years or older, using high-dose or adjuvanted formulations. Additionally, primary and annual booster COVID-19 vaccinations were recommended, along with a single dose of RSV vaccine for individuals aged 75 years and older, providing protection for at least two winter seasons. Routine administration of pneumococcal conjugate vaccine 15 (PCV15) or PCV20 was also recommended for adults aged 65 years or older who had not previously received a PCV.
conclusionsThe consensus provides a vaccination guide tailored to the Latin American context, aiming to bridge gaps in vaccination coverage among older adults in the region. This effort seeks to reduce the burden of respiratory diseases on frail healthcare systems and promote healthy aging in Latin America.
