The current pandemic has drawn attention to China's actual death rate and raised questions about medical supplies. The State Council held a press briefing in response to these concerns. Wu Zunyou, chief epidemiologist at the Chinese CDC, and Liang Wannian, head of the COVID-...
Another China CDC researcher Chen Cao noted that according to monitoring data, the XBB subvariants are now the predominant COVID-19 strains in both imported and local infections, with no significant change in pathogenicity. Underpinned by China's multi-channel monitoring and early warning system, ...

In the meantime, the composition of current COVID-19 vaccines may need to be updated in order to protect against the evolution of the virus. Such updates need to be based on strains that are genetically and antigenically close to the circulating variants. They should also elicit "broad, stron...
Coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) recently was declared a pandemic by world health organization (WHO) Due to sudden outbreaks, currently, no completely effective vaccine or drug is clinically approved. Several therapeutic strategies ...
"If you look at the structure ofomicronand compare it to the structure of previous strains, including delta, the site where there is the most change from the original strain is the spike protein," says Dr. Andrew Badley, chair of Mayo Clinic's COVID-19 Task Force. ...
COVID-19 vaccines were developed with an unprecedented pace since the beginning of the pandemic. Several of them have reached market authorization and mass production, leading to their global application on a large scale. This enormous progress was achie
Vaccinations conferred 95% effectiveness towards coronavirus infection in a prospective, placebo-controlled clinical study comprising about 44,000 respondents of Covid-19. SARS-CoV-2 strains, which had been initially found in the UK, South Africa, and Brazil, have spread worldwide with variations ...
As such, the S-protein has been similarly recognized as a significant target for COVID-19 vaccines. Notably, other studies have reported that the M-protein is capable of inducing the production of nAbs, and the N-protein contains T-cell epitopes in SARS-CoV; these proteins may also offer ...
These findings are expected given how the omicron variant differs from earlier strains of SARS-CoV-2, the COVID-19 virus. Omicron has dozens of mutations in the spike protein, which the virus uses to enter and infect cells. Most antibodies were designed to bind to and neutralize the original...
