As researchers estimate that nearly all Americans have been exposed to SARS-CoV-2, the virus that causes COVID-19, whether through infection or vaccination, we are no longer 'immunologically naive'—in other words, our immune systems are familiar with certain variants of SARS-CoV-2. This familiarity can pose a problem for vaccine development.

Study finds higher SARS-CoV-2 risk in obese individualsA study finds an increased risk of developing a productive SARS-CoV-2 infection in obese people. Obesity is known to predict worse outcomes and higher mortality for those with COVID-19. Masanori Aikawa and colleagues sought to determine if obesity also affected the likelihood of getting ill in the first place.

Synergistic mutations found in omicron variant of SARS-CoV-2Certain changes in the genetic material of pathogens can alter their ability to infect human cells or protect them better from defense by the immune system. Researchers were able to observe this effect particularly impressively in the SARS-CoV-2 virus.

To subvert immune response, SARS-CoV-2 stimulates production of proteins without protective functionTo evade the human host's immune response, SARS-CoV-2, the coronavirus that causes COVID-19 uses the machinery of defense cells to induce the expression of unproductive isoforms of key antiviral genes—variant forms of genes that result from disrupted splicing or transcription processes and do not code for functional (protective) proteins.

Antibody could offer sweeping protection against evolving SARS-CoV-2 virusResearchers at Northeastern say they've discovered how an antibody could provide broad protection against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the virus responsible for COVID-19—even as it evolves to outwit other of the body's chemical defenses.
