Study shows lower SARS-CoV-2 infection rates in smokers

Coronavirus disease 2019 (COVID-19) primarily infects the lungs, later spreading through the bloodstream. The worst prognoses are mostly seen in ‘at-risk’ groups, such as the immunocompromised, elderly, or those suffering from respiratory conditions.

Those undergoing treatment for hematological malignancies show reduced immune response to COVID-19 vaccines

Researchers recently investigated the effect of infection with SARS-CoV-2 in patients with hematologic malignancies in minority populations.

Three doses of inactivated BBIBP-CorV SARS-CoV-2 vaccine induce robust B and T cell responses

To investigate the immune memory sustainability of SARS-CoV-2-specific B cells and T cells, stimulated by the inactivated vaccine, and the potential need for a third booster dose in healthcare workers (HCWs), a non-randomized trial was undertaken by researchers at Sun Yat-sen University in Guangzhou, China. the research is posted online on the medRxiv* preprint server.

Quantification of salivary IgG and IgA against SARS-CoV-2

Salivary antibody levels are many fold lower than found in blood serum, Immunoglobulin G (IgG) in the saliva is mainly sourced from leakage from the gingival surface and Immunoglobulin A (IgA) from mucosal membranes.

Study examines efficacy Pfizer-BioNTech vaccine among USAF Academy Cadets

A new study published on the medRxiv* preprint server has estimated the effectiveness of vaccines in preventing COVID-19 as a function of time since vaccination.

SARS-CoV-2 antibodies in breast milk: Study

A new study published on the medRxiv* preprint server explores the presence of immunoglobulin (Ig) antibodies IgA and IgG against SARS-CoV-2 in breast milk secreted by women with confirmed infection. The scientists also delineated the specific antigens targeted by the antibodies.

Study reports on COVID-19 vaccine uptake and antibody prevalence in England during May 2021

A new study reports this finding, along with varying antibody prevalence among different groups and regions and between different age groups. In the current paper, available as a preprint on the medRxiv* server, the results of the sixth round of the REACT-2 study are reported.

An assay capable of detecting SARS-CoV-2 antibodies in breast milk and other samples

In a recent study by US researchers (currently available on the medRxiv* preprint server), a specific immunoassay based on the spike glycoprotein’s receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not only well suited for the detection of antibody response after infection and vaccination but may also represent a method of choice when conducting seroepidemiological studies.
