Patients with Trichinella spiralis infection display unmodified antigen-specific immune response to SARS-CoV-2.

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
backgroundThrough coevolution, helminths have developed immunomodulatory mechanisms that regulate exaggerated host immune responses and may influence immune responses to coinfections or vaccines. The coronavirus disease 19 (COVID-19) pandemic has raised concerns about how such infections might affect vaccine-triggered immune responses.
objectivesThe aim of the study was to investigate how ongoing Trichinella spiralis infection affects the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in individuals already vaccinated or virus-primed, during Trichinella outbreak in Serbia.
methodsAmong 21 individuals who tested positive for anti-Trichinella antibodies, 15 were included in the study, which allowed for the first time to examine the impact of Trichinella infection on the humoral and cellular immune response to the SARS-CoV-2 using flow cytometry.
findingsThe results showed that Trichinella infection did not impair antibody production or cellular responses to SARS-CoV-2. Specifically, anti-SARS-CoV-2 antibodies and memory B cells remain unaffected, and T cells (CD4+ and CD8+) responded to SARS-CoV-2 antigens by generating pro-inflammatory cytokines. MAIN
conclusionsTrichinella spiralis infection does not disrupt the host's humoral or cellular immune response to SARS-CoV-2, suggesting that the use of Trichinella antigens for the treatment of chronic inflammatory disorders, which is promising, will not affect the host's ability to respond to future viral challenges.
