The inflammatory response from adaptive immune cells – such as B and T lymphocytes – clears the body of the SARS-CoV-2 virus, but at the same time, it also causes the characteristic symptoms of COVID-19, a new study finds.
New research used engineered mice to compare SARS-COV-2 omicron subvariants, and found one of them, BA.5, was more virulent likely due to its ability to rapidly replicate early during infection.
Severe COVID-19 infection triggers changes that affect gene expression in immune system stem cells, causing alterations in the body’s immune response, according to a new study by Weill Cornell Medicine and Jackson Laboratory investigators.
Pregnant women who had a previous COVID-19 infection and received full vaccination and a booster have the strongest immune protection from the disease – and pass that protection along to their unborn babies, according to a new study.
During the COVID-19 pandemic, many U.S. hospitals had overcapacity intensive care units while other area hospitals had open ICU beds available, a phenomenon known as “load imbalance.”
A new study led by Weill Cornell Medicine and NewYork-Presbyterian investigators has found that the risk of long COVID and its symptoms present very differently across diverse populations and suggests that further investigation is needed to accurately define the disease and improve diagnosis and treatment.
More research and oversight are needed before making permanent a pandemic policy that allows hospitals to treat acutely ill patients in their homes, according to new Cornell research.
People who refused to get vaccinated against COVID-19 had low levels of social trust, weak attachments to the rule of law, and were less willing to honor collective commitments to the greater good, according to Cornell research published today.
A treatment combining two antibodies against the coronavirus SARS-CoV-2 strongly protected high-risk people with early COVID-19 symptoms from hospitalization and death in an international Phase 2/3 clinical trial.
