Exposure to SARS-CoV-2 can induce virus-specific T cell responses without seroconversion

A new study by researchers at Strasbourg University Hospital and published on the preprint server medRxiv* in June 2020 shows that COVID-19 antibody responses may sometimes be lacking following exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This could lead to a significant underestimation of the number of infections and the number of individuals who have achieved immunity.

New dengue virus serotype DENV3 has re-emerged in Singapore after three decades

Dengue infections are rising, even as public health authorities are battling to contain the spread of the coronavirus. Dengue virus serotype 2 (DENV2) had previously been the predominant serotype but DENV3 has re-emerged in Singapore after almost three decades.

Antibodies against prevalent endemic human coronaviruses may provide cross-protection to SARS-CoV-2

Researchers from Qatar have demonstrated that antibody repertoires against endemic human coronaviruses are qualitatively different in children when compared to the general adult population, as well as healthy adult blood bank donors – and they may also provide cross-protection against epidemic/pandemic strains.

SARS-CoV-2 induces broad T cell response in recovering patients

A new study published on the preprint server bioRxiv in June 2020 shows that T cell responses in COVID-19 patients are broader and more robust in severe disease and are explicitly directed against spike, memory, and ORF3a proteins.

8.5 percent of COVID-19 patients do not seroconvert

A new study published on the preprint server medRxiv in June 2020 reports on the use of inexpensive and accurate ELISA and rapid diagnostic tests (RDT) to identify the demographic and clinical factors that affect the antibody response in COVID-19 patients.

Scientists create 'all-atom' model of SARS-CoV-2 spike protein

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes the coronavirus disease (COVID-19), an illness that has spread across the globe, infecting more than 9 million people. The novel coronavirus invades cells through "spike proteins," which sticks and binds itself to a host cell.

Single-dose Israeli vaccine candidate protective against SARS-CoV-2

Now, a new Israeli study published on the preprint server bioRxiv in June 2020 reports a new recombinant vaccine expressing the S or spike protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to be highly protective with a single dose in an animal model. This could be a gamechanger in the fight to contain the outbreak.
