COVID mRNA vaccines show diminished neutralization responses against Omicron

Researchers report an overview of antibody neutralization by all currently approved vaccines against the SARS-CoV-2 Omicron, Beta, and Delta VOCs.

Researchers suggest hybrid convalescent plasma therapy neutralizes the omicron variant

New research suggests convalescent plasma from unvaccinated donors is not effective against the Omicron variant, however, “hybrid” convalescent plasma from donors who recovered from COVID-19 infection and are vaccinated provides considerable antibody protection.

Study shows fully vaccinated individuals preserve cross-neutralizing memory B-cells against SARS-CoV-2 Omicron variant

A new study found increases in resting memory B cell subsets showed strong cross-reactivity against several variants, including Omicron.

29 Dec 2021

Study suggests saliva swabs may be more suitable for omicron detection

New study findings reveal that saliva samples are more useful than mid-turbinate samples for the accurate detection of omicron infection.

29 Dec 2021

Impact of an omicron outbreak at a private gathering in the Faroe Islands

New findings suggest that the Omicron variant has potent immune-escape capabilities, putting even newly boosted patients at risk of infection.

29 Dec 2021

3-dose vaccines deemed ultrapotent against diverse and highly transmissible SARS-CoV-2 Omicron and other variants

A new study found that the presence of a subset of antibodies with broad neutralizing activities against all circulating variants of concern in the three-dose vaccines' memory B-derived antibody repertoire suggests that the Omicron/future variants infection may elicit selective and rapid recall of humoral responses, conferring secondary protection directed by memory etched in the immune system.

Exploring immunogenicity and safety after a homologous booster dose of SARS-CoV-2 recombinant spike protein vaccine

Research suggests that a single booster dose of NVX-CoV2373 given approximately six months after the primary series induced significant increases in humoral antibodies, while also exhibiting an acceptable safety profile.

29 Dec 2021

Booster dose of mRNA vaccines found crucial in protecting against SARS-CoV-2 Omicron variants

A new study shows that Omicron is more infectious than any of the other variants and that booster vaccines, especially mRNA vaccines, are capable of neutralizing Omicron variants of pseudoviruses.

Pregnant women should not delay COVID-19 vaccination until late pregnancy, study suggests

COVID-19 vaccination of expectant mothers elicits levels of antibodies to the SARS-CoV-2 outer "spike" protein at the time of delivery that don't vary dramatically with the timing of vaccination during pregnancy and thus don't justify delaying vaccination, according to a study from researchers at Weill Cornell Medicine and NewYork-Presbyterian.

28 Dec 2021

Researchers investigate the effect of emerging SARS-CoV-2 mutations on ACE2 binding

Now in new research, scientists from the University of Leicester have been investigating how these mutations alter the affinities of RBDs to ACE2.

28 Dec 2021

Study demonstrates increased effectiveness of third BNT162b2 dose against SARS-CoV-2 infection and hospitalization

Researchers assess vaccine effectiveness of two and three doses of BNT162b2 against SARS-CoV-2 infections and COVID-19-related hospital admission.

28 Dec 2021

SARS-CoV-2 infection induces robust and cross-reactive immune responses in children

Researchers compare the convalescent humoral and cellular immune responses between children and adults infected with SARS-CoV-2.

28 Dec 2021

An evaluation of the association between COVID vaccination and myocarditis in 42 million people aged 13 or older

A new study posted to the medRxiv* pre-print server included individuals over 13 years of age receiving the third vaccine dose to further evaluate the association between myocarditis and COVID-19 vaccination or infection. The study took place from December 1, 2020, to November 15, 2021.

28 Dec 2021

SARS-CoV-2 Omicron variant neutralized by third BNT162b2 booster shot

A new preprint* research paper under consideration at Nature Portfolio Journal assesses the susceptibility of the Omicron variant to neutralizing antibody response after booster immunization.

28 Dec 2021

Pre-existing immunity against influenza can lower SARS-CoV-2 infection burden and spread

A recent study by a team of European researchers demonstrated how antibodies induced by currently circulating influenza A H1N1 strains can cross-react with the important part of the SARS-CoV-2 spike glycoprotein that interacts with the human cell receptor. Their paper is currently available on the medRxiv* preprint server while it undergoes peer review.

28 Dec 2021

Third BNT162b2 dose effectively neutralizes SARS-CoV-2 Omicron pseudovirus

The findings reveal that the Omicron neutralizing titers induced by the third vaccine dose are comparable to that achieved against the original Wuhan strain (wild-type SARS-CoV-2) by the two-dose regimen. The study is currently available on the medRxiv* preprint server while awaiting peer review.
