Vitamin D supplementation to prevent acute respiratory infections: systematic review and meta-analysis of stratified aggregate data.

Background: A 2021 meta-analysis of 37 randomised controlled trials (RCTs) of vitamin D supplementation for prevention of acute respiratory infections (ARIs) revealed a statistically significant protective effect of the intervention (odds ratio [OR] 0·92 [95% CI 0·86 to 0·99]). Since then, six eligible RCTs have been completed, including one large trial (n=15 804). We aimed to re-examine the link between vitamin D supplementation and prevention of ARIs.

is a globally disseminated pathogen that is the cause of over 100 million infections per year. The resulting diseases are dependent upon host susceptibility and the infecting serovar. As serovar Typhimurium induces a typhoid-like disease in mice, this model has been used extensively to illuminate various aspects of infection and host responses.
