Study reveals Omicron sub-lineages BA.4 and BA.5 escape neutralizing antibodies elicited in response to BA.1 infection

Researchers evaluated whether neutralizing immunity elicited against Omicron sub-variant BA.1 in unvaccinated and vaccinated individuals adequately protected against infection by Omicron sub-variants, BA.4 and BA.5.

Features of SARS-CoV-2 Omicron BA.2 sublineage spike protein

Researchers assessed the traits of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.2 sublineage spike (S) protein.

Study suggests aerosol transmission of antibodies may contribute to host protection against SARS-CoV-2

A new study has addressed the previously mentioned research gap and has investigated the possibility of transfer of aerosol containing SARS-CoV-2-specific antibodies between vaccinated and non-immune hosts

Schools' role in the spread of SARS-CoV-2

The Omicron wave of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)––the causative pathogen for coronavirus disease 2019 (COVID-19) and the current pandemic––led to rampant transmissions in schools. Therefore, the school-based viral transmission must be curtailed to reduce viral evolution and maintain children's in-person education.

Study estimates the elevated risks of COVID-19 breakthrough infection and hospitalization in fully vaccinated individuals with comorbidities

The current study aimed to understand both the risk of breakthrough infection and severe outcomes in this population.

Higher contact among vaccinated people may negatively influence vaccine effectiveness

In a new study, researchers reported that contact among vaccinated people could influence the effectiveness of COVID-19 vaccines.

The generation of SARS-CoV-2 virus-like particles in insect cells

Researchers have reported the development of a promising COVID-19 vaccine candidate which is based on SARS-CoV-2 VLPs, derived from the co-expression of the spike, membrane, and envelope structural proteins in the baculovirus expression system.

Epigenetic abnormalities in hematopoietic cells during fetal development cause idiopathic autism

An international research group led by Professor Toru Takumi (Senior Visiting Scientist, RIKEN Center for Biosystems Dynamics Research) and Researcher Chia-wen Lin at Kobe University Graduate School of Medicine has shown that idiopathic autism is caused by epigenetic abnormalities in hematopoietic cells during fetal development, which results in immune dysregulation in the brain and gut.

Safety and immunogenicity of three-dose vaccination with the Pfizer/BioNtech SARS-CoV-2 mRNA vaccine

A recent article published in the Med journal reported that the SARS-CoV-2 booster vaccinations enhance the SARS-CoV-2 Omicron sublineage neutralizations.

Artificial circular RNAs found to bypass cellular antiviral responses

Researchers produced artificial circular ribonucleic acid sponges in a permuted intron-exon system and showed that these did not activate innate immunity.

Understanding sex differences in the pathophysiology of SARS-CoV-2 infection

A recent study published in the journal Immunology analyzed whether sex mattered in the immune response to SARS-CoV-2.

29 Apr 2022

Study finds curcumin is a potential therapeutic agent against the Omicron variant of SARS-CoV-2

A recent study demonstrated that the phytochemical curcumin is a potent therapeutic prospect against the SARS-CoV-2 Omicron variant

KHN’s ‘What the Health?’: More covid complications for Congress

The week that Dr. Anthony Fauci declared the pandemic part of covid-19 over was also the week Vice President Kamala Harris and two Democratic members of the Senate tested positive for the virus.

28 Apr 2022

Study shows public health impact of covid-19 vaccines in the U.S.

A large US study published by The BMJ today finds that fewer people die from covid-19 in better vaccinated communities.

How do mosquito bites affect immunity?

A new study looks at the immunomodulatory effects of mosquito bites, using Aedes aegypti as the model species and humans as the host.

28 Apr 2022

Exploring oncolytic viral therapeutics and immunotherapies derived from DNA and RNA

A new review initially described the developments in cancer-based medicines that included vaccinations, vector-based techniques, and genome injection using DNA and RNA-based nucleic acid therapeutics.

28 Apr 2022

Nearly 60% of Americans infected by Omicron

A recent study published in the Centers for Disease Control and Prevention (CDC) Morbidity and Mortality Weekly Report (MMWR) assessed the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection-induced viral antibodies (Abs) seroprevalence in the United States (US).

28 Apr 2022

Researchers demonstrate the efficiency of T-cell immune response against the Omicron variant

Scholars from HSE University and the RAS Institute of Bioorganic Chemistry have demonstrated the efficiency of T-cell immune response against the Omicron variant of SARS-CoV-2.
