Adult respiratory vaccination in the Indian armed forces: Uptake, awareness, and opportunities for policy reform.
Article in Lung India : official organ of Indian Chest Society, 2026. 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
BACKGROUND AND
objectiveImmunisation reduces morbidity and mortality from vaccine-preventable diseases (VPDs). While childhood vaccination in India has improved, adult immunisation remains insufficient, especially among individuals with non-communicable diseases (NCDs). We aimed to evaluate vaccination coverage, awareness, and influencing factors among adults in a tertiary Armed Forces hospital.
methodsA cross-sectional observational study was conducted from April 2024 to April 2025 at an adult immunisation clinic in a tertiary Armed Forces hospital. Data from 2,645 adults were analysed using descriptive and inferential statistics to assess vaccine uptake and its association with demographic and clinical variables.
resultsAmong 2645 participants, 57.3% were male. Influenza (45%) and pneumococcal (47%) vaccines were most administered. Herpes zoster and Tdap vaccines had lower uptake (5.7% and 1.5%, respectively). Uptake was highest in those aged 60-70 years. Awareness of adult vaccination was noted in 24.56% and was significantly associated with higher uptake (P < 0.001). Prior hospitalisation also positively influenced vaccine acceptance (P = 0.02). Adverse events were predominantly mild (pain, swelling, fever) and showed no significant variation between vaccines.
conclusionAdult respiratory vaccination coverage remains suboptimal despite moderate influenza and pneumococcal uptake. Awareness and prior healthcare interactions significantly influence uptake. National adult immunisation strategies are urgently needed.
