Study analyzes the contribution of AI to cancer patient care and vaccine design

Artificial Intelligence/Machine Learning (AI/ML) is the development of computer systems that are able to perform tasks that would normally require human intelligence. AI/ML is used by people every day, for example, while using smart home devices or digital voice assistants.

Rapid antigen detection test for SARS-CoV-2 proves more effective than expected, large study reports

In what is believed to be the largest prospective study of its kind to date -; involving some 6,000 patients seen at the Baltimore Convention Center Field Hospital (BCCFH) during a 10-day period around the beginning of 2021 -; researchers at Johns Hopkins Medicine, the University of Maryland Medical Center, the University of Maryland School of Medicine and four other collaborators report that a rapid antigen detection test for SARS-CoV-2, the virus that causes COVID-19, proved more effective than expected when compared with virus detection rates using the established standard test, the polymerase chain reaction (PCR) assay.

Convalescent plasma not recommended for patients with covid-19, WHO experts say

Convalescent plasma (a transfusion of blood plasma from someone who has recovered from covid-19) is not recommended for patients with covid-19, says a WHO Guideline Development Group of international experts in The BMJ today.

Combination of prior infection and vaccination produces a more potent defense against SARS-CoV-2

Antibodies against the SARS-CoV-2 spike protein produced by the immune system can help identify and fend off future infections, but not all antibodies are the same.

SARS-CoV-2 surveillance in urban wildlife from Ontario and Québec

Researchers conducted SARS-CoV-2 surveillance in urban wildlife from Ontario and Québec, Canada.

Homologous mRNA and heterologous vaccines elicit high immune responses

New study findings show that homologous mRNA or heterologous vaccination induces the highest immune responses due to high RBD- and S1-specific antibodies.

Possible impact of spike protein mutations on SARS-CoV-2 Omicron variant

The current study not only analyses the mutations in the Omicron spike variant but classifies various combinations of spike mutations into groups.

Exploring SARS-CoV-2 vaccine responsiveness in immunosuppressed patients

A new study indicates an immunological response to SARS-CoV-2 vaccines in immunosuppressed patients that were comparable to healthy patients.

Community transmission of SARS-CoV-2 lineage with novel mutations in Florida

A new study describes the introduction and spread of a SARS-CoV-2 lineage, A.2.5 in Florida using samples from the Florida Department of Health (FDOH) Bureau of Public Health Laboratories (BPHL).

Scientists develop and characterize variant-specific vaccines against SARS-CoV-2

In a recent study conducted at Yale University, USA, scientists have investigated the immunogenicity of mRNA-based coronavirus disease 2019 (COVID-19) vaccine candidates encoding the spike proteins of different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. The findings reveal that the vaccines induce robust immune responses against SARS-CoV-2 variants. The study is currently available on the bioRxiv* preprint server.

COVID-19 severity is correlated with T cell receptor repertoire signatures

In a new study published in the bioRxiv* preprint server, researchers found that specific TCR sequences predicted the severity of coronavirus disease 2019 (COVID-19) infection. Additionally, there was evidence of increased CDR3 sequences and changes in k-mer motifs for patients with severe illness.

Omicron variant increases risk of SARS-CoV-2 reinfection

New surveillance data from South Africa published in the medRxiv* preprint server suggests that the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omnicron variant has the potential to escape naturally-acquired immunity. The research indicates people who previously recovered from a coronavirus disease 2019 (COVID-19) are at risk for reinfection with the Omicron variant. The results show that the risk of reinfection is greater with the Omicron variant versus Delta and Beta.
