Poor timing of flu vaccinations associated with poor birth outcomes and cesarean births

With flu season approaching in the United States, new research from an international team of scientists testifies to the importance of timely vaccination: Poor timing of influenza vaccination campaigns in the semi-arid region of Brazil led to an increase in premature births, lower birth-weight babies and the need to deliver more babies by cesarean section, the researchers found.

COVID-19 vaccination induces transient increase in cellular and antibody responses to S1 antigenic sequence

Scientists have characterized T-cell, B-cell, and IgG responses to S antigenic sequences to evaluate vaccine effectiveness.

Comparing lateral flow testing with RT-PCR to detect SARS-CoV-2

Lateral flow devices (LFDs) are point-of-care tests that require significantly more time to develop than RT-PCR assays but can be used locally with minimal to no training, some of which can provide results in as little as 30 minutes. However, there have been some worries about the sensitivity of such kits. As a result, researchers from Micropathology Ltd have been comparing the two methods.

How long does natural immunity produced by SARS-CoV-2 infection last?

A new study posted to the bioRxiv* preprint server followed the adaptive immune response in convalescent patients from Swedish and Italian cohorts—which had earlier shown long-lasting adaptive immune responses to the G614 strain—for 15 months. Here, specific antibody levels and neutralizing antibody titers were tested against variants of concern (VOCs).

Novel therapy approach could stop tumor growth

The immune system protects the body from cancer. To protect healthy body cells from its own immune system, they have developed a protective shield: the protein CD47 is a so called "don't eat me" signal, which tells the immune cells to stand back.

Rapid measurement of SARS-CoV-2 spike T-cells

Researchers measure SARS-CoV-2 T-cell responses in individuals vaccinated or in those who developed immunity from a prior natural infection.

Vaccinated children induced significantly higher antibody titers than naturally SARS-CoV-2 infected children

A recent preprint discusses the antibody response to the nucleic acid vaccines against SARS-CoV-2 when administered to children aged 7-11 years.

A new bacterial two-hybrid assay to study SARS-CoV-2 interactome

Recently, scientists have developed a bacterial two-hybrid (B2H) system to study the PPIs of SARS-CoV-2 in a heterologous non-eukaryotic system. This study is available on the bioRxiv* preprint server. Put simply, the B2H system could be used to analyze the SARS-CoV-2 proteome.

COVID-19 vaccination elicits broader antibody response to SARS-CoV-2 spike than infection

A recent study demonstrates that antibodies generated in response to mRNA-based COVID-19 vaccination target more epitopes across the spike protein.

Delta variant exhibits immune evasion, enhanced cell entry, and augmented syncytium formation

Researchers addressed the question of using reporter particles pseudotyped with the S protein of SARS-CoV-2, which are suitable tools to examine SARS-CoV-2 neutralization antibodies.

Vaccine-induced memory B cells can recognize SARS-CoV-2 variants

Researchers have been investigating the effect that memory B cells produced in individuals who have received an mRNA vaccine have against SARS-CoV-2 variants.

Sero-epidemiological insights into pathways to COVID-19 immunity

A new study posted to the medRxiv* server attempts to utilize serology as a tool to identify disparities in infection rates and vaccination coverage.

Research finds different antibody responses following COVID vaccination and natural infection

A new study published in the journal Nature attempted to investigate memory B cell evolution 5 months after vaccination with mRNA vaccines such as Moderna (mRNA-1273) or Pfizer-BioNTech (BNT162b2) in SARS-CoV-2 naïve individuals. The study explored various aspects of memory B cell antibody response like neutralizing response, affinity, epitope targeting, and neutralizing breadth.
