Researchers have found a causal link between caesarean section birth, low intestinal microbiota and peanut sensitivity in infants, and they report the effect is more pronounced in children of Asian descent than others, in a recently published paper in the journal of the American Gastroenterological Association.
An overgrowth of yeast in the gut within the first few months of life may cause changes to the immune system that increase the risk of asthma later on, shows a study published today in eLife.
University of Minnesota Medical School researchers have offered new ways to think about the immune system thanks to a recent study published in Nature. Their research, which indicates organ tissues become increasingly immune throughout life, may begin to alter fundamental ideas regarding the rules of vaccination and the immune system's function within the body.
The researchers compared the R (basic reproduction number) of the original SARS-CoV-2 virus with the R of the British variant, and found that the British variant is almost 1.5 times more infectious. The researchers: "The study proves that active monitoring of at-risk populations and prioritized vaccination programs can prevent hundreds of deaths."
COVID-19 can enter the body via the lungs and gut, and a new study suggests the gut's immune response alone may not provide adequate whole-body immunity from the virus. Blood samples analyzed from COVID-19 patients revealed that immune cells triggered by the gut's response to infection were limited in number when compared to immune cells triggered elsewhere in the body. While more research is needed, these findings could have implications for planned oral COVID-19 vaccines.
Ensuring COVID-19 vaccine access for refugee and displaced populations, and addressing health inequities, is vital for an effective pandemic response. Yet, vaccine allocation and distribution has been neither equitable nor inclusive, despite that global leaders have stressed this as a critical aspect to globally overcoming the pandemic.
A new machine-learning program accurately identifies COVID-19-related conspiracy theories on social media and models how they evolved over time--a tool that could someday help public health officials combat misinformation online.
Researchers have discovered that POT1, a gene known to be associated with risk of glioma, the most common type of malignant brain tumor, mediates its effects in a sex-specific manner.
Experts have narrowed the group of individuals with prior allergies who should see an allergist before receiving a COVID-19 vaccine. Allergy evaluation with skin testing prior to COVID-19 vaccination is rarely needed.
COVID-19 patients who are overweight or obese are more likely to develop a more severe infection than patients of healthy weight, and they require oxygen and invasive mechanical ventilation more often. There is no increased risk of death . These conclusions, for which more than 7,000 patients were studied, appear from international research in eleven countries, including the Netherlands (Radboud university medical center).
