Measures that could have been taken at the beginning of the pandemic were not implemented as precautionary preparation but rather as reactionary to an already spreading virus, making it hard to contain.
COVID-19
Is there long-term immunity for SARS-CoV-2?
SARS-CoV-2 antibodies were found in patients’ blood up to 7 months after infection, and researchers are hopeful.
Moderna’s COVID-19 vaccine shows immune response in elderly patients
A small trial indicates that Moderna’s experimental SARS-CoV-2 vaccine is effective and safe in older adults, a population group most vulnerable to severe COVID-19.
Can the pneumonia vaccine protect against COVID-19?
Where pneumococcal vaccination rates are high, COVID-19 cases are low and vice-versa.
Striking images of SARS-CoV-2 infected cells
Researchers capture high-powered microscopic images showing startlingly high SARS-CoV-2 viral loads on human respiratory surfaces.
AstraZeneca COVID-19 vaccine trial put on hold
The global trial run by researchers at Oxford and AstraZeneca has been paused due to an adverse reaction at a UK site. Whether the reaction is related to the vaccine is still unknown.
Face shields less effective against spreading COVID-19
Face shields and masks with exhalation valves found to be ineffective for stopping COVID-19 from spreading.
Nasal vaccine against SARS-CoV-2 prevents infection and spread throughout the body
Study claims nasal delivery protects first site of infection and produces widespread immune response compared to intramuscular injection.
Researchers show children are silent spreaders of virus that causes COVID-19
Comprehensive pediatric study examines viral load, immune response and hyperinflammation in pediatric COVID-19.
COVID-19 clinical trials lack diversity
Trials need more people of color to generalize results to larger US population.
