CDC study on efficacy of mRNA vaccines against symptomatic COVID-19

A new study posted to the medRxiv* preprint server derives measures of substantial efficacy for these vaccines in preventing mild to moderate COVID-19 from a group of outpatients with and without a history of vaccination.

How SARS-CoV-2 vaccination symptoms differ from early COVID-19 symptoms

A new study published on the preprint server medRxiv* presents an analysis of the differences between recorded vaccination side effects vs. early COVID-19 symptoms. The researchers focused on four vaccines, namely, Pfizer-BioNTech (PB) mRNA (BNT162b2) vaccine, based on messenger ribonucleic acid encoding the viral spike protein; the Moderna mRNA (mRNA-1273) vaccine; the Oxford-AstraZeneca (O-AZ) adenovirus-vectored vaccine; and the Janssen adenovirus-vectored Ad26.COV2.S).

First dose of Pfizer-BioNTech or Oxford-AstraZeneca vaccines has strong protective effect against COVID-19 in older adults

A new study estimates vaccine effectiveness against COVID-19 mortality in England using the RDD approach.

Efficacy of mRNA vaccine-induced memory B cells against SARS-CoV-2 variants

A new study characterizes the functional humoral immunity post-COVID-19 mRNA-based vaccination.

Pfizer vaccine and isolation independently associated with reduced household transmission of SARS-CoV-2

Israel was among the leading proponents of COVID-19 vaccination as the way out of the current worldwide restrictions on social and economic interactions and activity. A new study, recently released as a preprint on the medRxiv* server, reports on the effects of the large-scale vaccination campaigns carried out in this country, relating to successful control of SARS-CoV-2 spread within households.

Study suggests COVID-19 vaccine confidence and hesitancy in the UK driven by trust, not misinformation

An interesting new study reports that vaccine hesitancy in the UK is driven not, as is commonly thought, by the so-called ‘infodemic’ of misinformation that has characterized much public messaging during the COVID-19 pandemic. Instead, the personality of the individual, the ability to trust scientific and government leadership, political affiliations, and openness relative to the process of vaccine development was found to be key in the development of this attitude.

Evaluation of a synthetic DNA SARS-CoV-2 vaccine INO-4800 using a nonhuman primate model

A new study published in Vaccine assesses the safety and efficacy of the synthetic DNA vaccine candidate INO-4800, delivered as a single or double dose regime.

Mixing COVID vaccines generates a comparable immune response

The validity and safety of mixing first and second doses of different types are explored in a paper recently uploaded to the preprint server medRxiv* by Rose et al. (July 13th, 2021), finding that robust antibody response is induced, comparable to, and perhaps even exceed that generated by homologous dosing.

COVID-19 researchers review 184 drug repurposing candidates

New research describes the use of integrative bioinformatics analyses of transcriptomic profiles for COVID-19 therapeutics.

Nanopore technology allows point-of-care SARS-CoV-2 genomic sequencing

As the SARS-CoV-2 continues to spread worldwide and cause disease and death on a devastating scale, genomic sequencing has become a primary method of keeping track of emerging variants and new outbreaks. A new medRxiv* preprint explores the role of nanopore sequencing in this effort.

COVID-19 vaccine booster strategy against Delta variant evidence of growing inequity, says WHO

Could the COVID-19 vaccine booster dose strategy being planned in wealthyy nations underscore issues of health inequality?

Scientists identify existing drugs that may inhibit SARS-CoV-2 virus

The COVID-19 pandemic has caused more than 600,000 deaths in the United States since the start of 2020 and more than 4 million globally.

Colonization by SARS-CoV-2 not synonymous with infection, screening study highlights

A new study released as a preprint on the medRxiv* server throws cold water on this notion, however, by demonstrating that in a set of asymptomatic cases, less than a tenth actually had evidence of SARS-CoV-2 infection. This finding has serious implications for the practices mentioned above, since they may be neither justifiable nor cost-effective as means to break the chain of viral transmission.

SARS-CoV-2 immunity due to prior infection or vaccination is similar, study says

A new study finds that the rate of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection is low following one episode of the infection.

Initial SARS-CoV-2 vaccination response may predict BNT162b2 booster response, but not AZD1222

A new study finds that the antibody titer values prior to the booster dose of the BNT162b2 vaccine can predict the final antibody response after two doses.

B.1.427/B.1.429 variant of SARS-CoV-2 evades neutralization via disulfide bond rearrangement

A new paper discusses an intriguing new mechanism of immune evasion traceable to specific mutations in the B.1.427/B.1.429 variant of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Mother-to-baby SARS-CoV-2 transmission in pregnancy possible but rare, says study

A new meta-analysis, released on the medRxiv* preprint server, suggests that, though possible, the virus is rarely transmitted to the newborn in real life. A scientific brief from the World Health Organization (WHO) in February 2021 describes three mechanisms by which the virus might be transmitted from the mother to the fetus or newborn.

New study reports low SARS-CoV-2 breakthrough infections in vaccinated healthcare workers

Researchers examined cases of SARS-CoV-2 infection in fully and partially vaccinated healthcare workers, finding that vaccination provided strong immunity to the virus even though VOCs are on the rise in the non-vaccinated community at large.

Study examines evolution and avidity of anti-SARS-CoV-2 IgG antibodies after mRNA vaccination

New research released on the medRxiv* preprint server has measured antibody responses in 71 mRNA vaccinated adults (54 vaccinated with Pfizer and 17 vaccinated with Moderna).
