Do previously infected people still benefit from vaccination against COVID-19?

In a recent study published in PLOS medicine, researchers determined the vaccine effectiveness (VE) of the primary vaccination course for coronavirus disease 2019 (COVID-19). They determined VE against reinfection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), COVID-19-related hospitalization and mortality. In this way, the researchers assessed the effect of time since vaccination during the … Read more

The relationship between neutralization levels and observed efficacy against asymptomatic and symptomatic infection of ten COVID-19 vaccines

In a recent study published on the medRxiv* server, researchers determined whether levels of neutralizing antibodies (NAb) were predictive of the efficacy of fractional vaccine doses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Study: Predictive efficacy of vaccine dose fractionation using neutralizing antibody levels. Image credit: peterschreiber.media/Shutterstock Background During the 2016 yellow fever … Read more

Can SARS-CoV-2 be inactivated by resonance caused by sound waves at the ultrasonic frequency?

In a recent study posted on the bioRxiv* preprint server, researchers conducted in vitro experiments to test the ability of different frequencies of ultrasound to inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Study: Ultrasound treatment inhibits in vitro infectivity of SARS-CoV-2. Image credit: NicoElNino/Shutterstock Background The 2019 coronavirus disease (COVID-19) pandemic has resulted in … Read more

Myocarditis after COVID vaccination is rare, but more common in younger men

In a recent study published in the Journal of the Canadian Medical Association, researchers observed the incidence of myocarditis after messenger ribonucleic acid (mRNA)-based vaccination against coronavirus disease 2019 (COVID-19). In addition, they compared their estimates to expected rates based on the historical rates assessed before the COVID-19 vaccine rollout in British Columbia (BC), Canada. … Read more

Proteomic analysis identifies novel phenotypes associated with COVID-19 severity in circulating immune cells

In a recent study posted on the medRxiv* preprint server, researchers used proteomic analysis to identify novel immune cell phenotypes associated with severe coronavirus disease 2019 (COVID-19). In addition, they collected cumulative dysregulation of immune cells in progressive disease. Study: Proteomic analysis of circulating immune cells identifies novel cellular phenotypes associated with COVID-19 severity. Image … Read more

Approved and development of passive and active immunizations against respiratory syncytial virus in childhood and pregnancy

In a recent study published in Journal of Pediatricsresearchers investigated active and passive childhood vaccination against respiratory syncytial virus (RSV). Study: Current strategies and perspectives for active and passive immunization against respiratory syncytial virus in childhood. Image credit: ART-ur/Shutterstock Background Despite the global importance of RSV infections in children, only one monoclonal antibody, Palivizumab, has … Read more

Powerful hypervalent nanoparticles against variants of HIV, Lassa and SARS-CoV-2

In a recent study published in the journal Advanced scienceresearchers developed molecularly imprinted nanoparticles (nanoMIPs) with broad-spectrum activity against deadly viruses. Study: rational development of hypervalent glycan shield-binding nanoparticles with broad-spectrum inhibition against deadly viruses, including SARS-CoV-2 variants. Image credit: Kateryna Kon/Shutterstock Viral infectious diseases pose a serious threat to humans. The recent outbreak of … Read more

successful culture of replicating SARS-CoV-2 from hospital aerosol samples after freezing

In a recent study posted on the medRxiv* preprint server, researchers demonstrated the presence of infectious severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in samples from the hospital rooms of SARS-CoV-2 infected patients. Study: Detection of infectious SARS-CoV-2 in frozen aerosol samples collected from hospital rooms of patients with COVID-19. Image credit: creativeneko/Shutterstock Background While … Read more

How gut microbes influence the immune response to SARS-CoV-2

An article published in Critical Assessments in Food Science and Nutrition journal reviews the role of the gut microbiota in shaping the host immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Study: Gut microbiome and antiviral immunity in COVID-19. Image credit: Design_Cells / Shutterstock Background SARS-CoV-2, the causative agent of the 2019 coronavirus … Read more
