Waning immunity may heighten risk, but milder reinfection may follow severe infection. It may be possible to have two completely separate bouts of COVID-19, doctors…

Food rich in vitamin D. Study indicates that some vitamins, steroids and antivirals could bind to the Spike protein, and may inhibit virus infectivity, whereas…
Australian researchers reveal new molecules that provide profound protection in asthma models — as well as reducing severity of asthma attacks. A study designed to…
Research shows that certain segments of the population who contract SARS-CoV-2, the strain of the virus that causes COVID-19, tend to get sicker and are…

New research shows that non-steroidal anti-inflammatory drugs (NSAIDs) reduced both antibody and inflammatory responses to SARS-CoV-2 infection in mice. The study appears this week in…
Rhesus macaques develop promising immune response to SARS-CoV-2; Results suggest lasting immunity after infection. In a promising result for the success of vaccines against COVID-19,…
Research led by the University of Birmingham and Birmingham Women’s and Children’s NHS Foundation Trust has revealed new insight into the biological mechanisms of the…

Protective immunity against SARS-CoV-2 could last eight months or more. New data suggest that nearly all COVID-19 survivors have the immune cells necessary to fight…
UC San Francisco scientists have discovered a new way to control the immune system’s “natural killer” (NK) cells, a finding with implications for novel cell…
Wuhan City in China was the first place to report COVID-19 in the world and — between December 2019 and May 2020 — caused nearly…

In an in-depth study, NIH researchers consistently found blood vessel damage in the brains of COVID-19 patients but no signs of SARS-CoV-2 infections. Here is…

COVID-19 antibodies preferentially target a different part of the virus in mild cases of COVID-19 than they do in severe cases, and wane significantly within…

The coronavirus SARS-CoV-2 docks with its spike protein onto the receptor-ACE2 found on the surface of lung cells. The levels of co-expressed genes with the…
Mini Antibodies Produced by a Llama and Isolated by Neuroscientists Could Prevent COVID-19 Infection
NIH scientists showed that nanobodies isolated from a llama may prevent COVID-19 infections. Infections happen when SARS-CoV-2 virus spike proteins (yellow) latch onto ACE2 receptors…
