Compared with drugs and influenza vaccines, vitamin D supplementation as a way to prevent influenza is more convenient and more acceptable due to its safety and many other benefits in maintaining bone health. Vitamin D did not have an impact on immunological effects of influenza vaccines (44, 45).
The establishment of a clear link between vitamin D status and influenza infection has broad implications for influenza research, especially in groups that are likely to have low vitamin D levels, as well as the formulation of policy regarding vitamin D supplementation.
8 lut 2019 · Conclusions: Vit-D supplementation promotes a higher TGFβ plasma level in response to influenza vaccination without improving antibody production. This supplementation seems to direct the lymphocyte polarization toward a tolerogenic immune response.
15 lut 2017 · A new global collaborative study has confirmed that vitamin D supplementation can help protect against acute respiratory infections. The study, a participant data meta-analysis of 25 randomized controlled trials including more than 11,000 participants, has been published online in The BMJ.
16 sie 2018 · Vitamin D levels in serum and influenza antibody titers were measured prior to and 21 days post-vaccination with live attenuated or inactivated influenza vaccine. Surprisingly, low vitamin D levels were associated with higher antibody titer against live attenuated virus, and this effect was strain-specific ( p < 0.05).
8 paź 2019 · But scientists found that baseline vitamin A and D levels were linked to immune responses to the vaccine. A clinical trial studied the flu vaccine and vitamin supplements in children 2–8 years old. Children got two doses of the vaccine either with a vitamin A and D supplement or a placebo.
2 kwi 2020 · This article reviews the roles of vitamin D in reducing the risk of respiratory tract infections, knowledge about the epidemiology of influenza and COVID-19, and how vitamin D supplementation might be a useful measure to reduce risk.
