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.

New strategy to create a cheap and rapid COVID-19 test based on isothermal amplification

Russian researchers have developed a strategy to create a cheap and rapid COVID-19 test based on isothermal amplification. According to their publication in Applied Biochemistry and Microbiology, use of this strategy will make it possible to create universal test systems for any of the COVID-19 variants.

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.

Estimating the epidemic potential of SARS-CoV-2 Omicron variant in South Korea

Researchers in South Korea and France have conducted an analysis on individuals infected with Omicron variant (B.1.1.529) of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to estimate the epidemic potential and long-term prospects of this virus in circulation. They have found that the basic reproduction number (R0) for this variant is 1.90, while the mean serial interval is 2.22 days.

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.

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.

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.

Study highlights importance of positive and negative selection in evolution of SARS-CoV-2 variants

Researchers from the University of Colorado Anschutz Medical Campus have been investigating the changes imparted on the Gamma variant by three RBD mutations.

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.

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.

28 Dec 2021

New report on 1.23 million breakthrough symptomatic SARS-CoV-2 infections by vaccine

A new research letter evaluates whether the estimated vaccine effectiveness changes against infection over time.

Double-dose mRNA COVID vaccines effective among dialysis patients

Researchers assess the impact of lesser initial vaccine response and subsequent waning antibody levels on clinical outcomes among maintenance dialysis.

28 Dec 2021

Study suggests spike mutation makes SARS-CoV-2 Omicron milder

The Omicron spike is relatively poorly cleaved and impaired in mediating cell-cell fusion and syncytia formation, contrary to predictions.

28 Dec 2021

Researchers discover antibodies that neutralize omicron and other SARS-CoV-2 variants

An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants. These antibodies target areas of the virus spike protein that remain essentially unchanged as the viruses mutate.

28 Dec 2021

COVID isolation and quarantine period for general population shortened by CDC

Given what we currently know about COVID-19 and the Omicron variant, CDC is shortening the recommended time for isolation from 10 days for people with COVID-19 to 5 days, if asymptomatic, followed by 5 days of wearing a mask when around others.

SARS-CoV-2-induced kidney damage

Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) infects the kidneys and contributes to tissue scarring, as shown by researchers from the RWTH Uniklinik Aachen, Germany, and Radboudumc, The Netherlands. The developed scar tissue in the infected kidneys may suggest a possible impact on kidney outcomes in the long term.

27 Dec 2021

APOE4 allele gene linked to increased risk of severe COVID-19

A study conducted at the University of Helsinki and the Helsinki University Hospital suggests that the APOE4 allele may also increase cerebral microhemorrhages related to COVID-19 and associate with mental fatigue related to long COVID.

Changes to the health and care visa could boost the recruitment of social care workers

Thousands of additional care workers could be recruited to boost the adult social care workforce following temporary changes to the health and care visa to make social care workers, care assistants and home care workers eligible for a 12-month period.
