In a study examining the ageing immune system and what makes it less efficient, researchers looked at the effects of COVID-19 mRNA vaccination in older adults. They found that older adults’ weaker immune response can be attributed to their relative deficiency in a specific type of T cells. As we age, the immune system’s efficacy […]
First-line immune defences against COVID-19 are short-lived and may explain reinfection. A new study finds that antibodies produced in the nose decline nine months after COVID-19 infection, while antibodies found in the blood last at least a year. Antibodies in the nasal fluid (known as immunoglobulin A, or IgA) provide first-line defence against COVID-19 by […]
New study suggests better approach in search for COVID-19 drugs: Research from the University of Kent, Goethe-University in Frankfurt am Main, and the Philipps-University in Marburg has provided crucial insights into the biological composition of SARS-CoV-2, the cause of COVID-19, revealing vital clues for the discovery of antiviral drugs. Researchers compared SARS-CoV-2 and the closely […]

CSIRO scientists publish new research on SARS-COV-2 virus ‘survivability’: COVID-19 causing virus lasts for 10 days longer than Influenza on some surfaces. Lower temps, glass, stainless steel and paper banknotes give virus longer life. Researchers at CSIRO, Australia’s national science agency, have found that SARS-CoV-2, the virus responsible for COVID-19, can survive for up to […]
