Is B.1.617.2 more transmissible than earlier SARS-CoV-2 variants?

A new study, released as a preprint on the medRxiv* server, reports that the B.1.617.2 variant is possibly more transmissible than earlier variants, based on the discovery that the serial intervals were not prolonged with this strain.

Could the COVID-19 vaccination rollout protect against future coronavirus outbreaks?

A new study suggests that the rollout of vaccines against the COVID-19 pandemic may be significant not only in preventing infections by SARS-CoV-2 but other endemic and pandemic-potential coronaviruses (CoVs) as well.

Study reports on the immunogenicity of single-shot COVID-19 vaccine against SARS-CoV-2 variants

In the three months since Johnson & Johnson's COVID-19 vaccine received emergency use authorization from the U.S. Food and Drug Administration, more than 10 million Americans have received the vaccine, according to the Centers for Disease Control and Prevention.

What are the challenges of SARS-CoV-2 serosurveillance in COVID-19 vaccine recipients?

An opinion paper by researchers from the US and Italy recently discussed various aspects of monitoring anti-SARS-CoV-2 antibodies before and after receiving COVID-19 vaccination to highlight the pros and cons of this monitoring strategy. This paper is published in the open-access journal Diagnostics.

Mix and match COVID-19 vaccines safe and effective: German study

A new preprint study posted to the medRxiv* server shows an AstraZeneca’s ChAdOx1-nCov-19 and Pfizer/BioNTech BNT162b2 COVID-19 vaccine combination is immunologically superior to two AstraZeneca ChAdOx1-nCov-19 doses.

Potent antibody responses to BNT162b2 COVID-19 vaccine among Japanese healthcare workers

In a paper recently uploaded to the preprint server medRxiv* by Nakajima et al. (June 4th, 2021), the antibody responses of over 2,000 Japanese healthcare workers were tracked over a period of several months, with particular regard to serum Immunoglobulin G (IgG) against the SARS-CoV-2 spike protein.

The potential of mRNA vaccines for a wide range of diseases

A new review article published in the journal Briefings in Functional Genomics focuses on the general characteristic features and mechanisms of mRNA vaccines. Further, this review has summarized the current progress of mRNA vaccines that have been developed for wide-ranging diseases, including COVID-19 disease.

Cell-to-cell contact helps in spreading SARS-CoV-2, finds study

People aren’t the only ones who should be social distancing — new research shows our cells need to as well. Researchers from Ohio State University in Columbus, Ohio, USA, used in-culture techniques to confirm SARS-CoV-2 transmission via cell-to-cell contact.

What lessons have we learned over a year into the COVID-19 pandemic?

One of the pressing questions scientists are currently trying to answer is whether the current vaccines will remain effective against the emerging SARS-CoV-2 variants of concern. A new piece of research has been published in the journal Biomedicines, which discusses the knowledge we have gained thus far and the questions that researchers should address in future work.

What is the role of monoclonal antibody therapy in treating COVID-19?

A new study has been published in the journal Vaccines that deals with the present state of research on using mAbs for the treatment of the COVID-19 disease. Many clinical trials are being conducted to evaluate the efficacy and safety of several newly designed mAbs. Some of the mAbs are directed towards immune system responses, i.e., non-SARS-CoV-2 specific mAbs, while others are devised to neutralize the SARS-CoV-2 protein structure, i.e., SARS-CoV-2 specific mAbs.
