Rollouts of the shot have ground to a halt following reports of blood clots, but health authorities say that these fears are unfounded and vaccination programs should continue.
Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.
New data suggest that the company’s approved COVID-19 vaccine protects against different virus variants, but could be less effective against the one that originated in South Africa.
An additional mutation in the spike protein of the coronavirus may help it elude antibody recognition, and scientists are investigating if current vaccines will protect against it.
Half a year after infection, people who had recovered from COVID-19 had robust antibodies, along with traces of the virus in their gut, which may drive long-lasting immunity.
Adenovirus vectors deliver the genetic instructions for SARS-CoV-2 antigens directly into patients’ cells, provoking a robust immune response. But will pre-existing immunity from common colds take them down?
A clinical trial of the shot in eight volunteers suggests that it is safe and that it generates antibodies that neutralize SARS-CoV-2, but further testing is needed, scientists say.
The 2019 Lasker medical and research awards celebrate advances in scientists’ understanding of T and B cells, Herceptin antibodies for treating breast cancer, and vaccine coverage around the globe.
