Transplant recipients benefit from a COVID-19 vaccine booster

A new preprint research paper posted to the medRxiv* server describes the reduction in humoral immunity in SOTR following vaccination, as well as the improvement with an additional dose of the vaccine.

BNT162b2 provides low vaccine responders adequate anti-spike and neutralizing antibodies to prevent SARS-CoV-2

A new study, published on the medRxiv* preprint server, investigated the changes in SARS-CoV-2 antibody levels among HCWs after SARS-CoV-2 vaccination. The study also assessed whether low responders produced sufficient SARS-CoV-2 anti-spike and neutralizing antibodies.

Experts cautiously optimistic about risks of Delta-Omicron mutations mix

Researchers evaluate the risk of the P681R, N501Y, and D614G mutations of current interest co-occurring naturally due to convergent evolution.

Efficacy of antibodies induced by natural infection, vaccination, or both against SARS-CoV-2 Omicron and Beta variants

A study has demonstrated that antibodies induced by two-dose COVID-19 vaccination or natural infection exhibit very low neutralizing activity against the omicron variant of SARS-CoV-2.

Characteristics and outcomes in patients hospitalized with COVID-19 in South Africa

A new research letter assessed patients hospitalized with a positive SARS-CoV-2 test during the fourth wave compared to the previous waves.

Study finds pan-sarbecovirus nanobodies can enhance development of super-immunity

A new study found that applying pan-sarbecovirus nanobodies shows a strong affinity toward all sarbecovirus clades and neutralized SARS-CoV-2 receptor binding domains

SARS-CoV-2 spike T cell responses from vaccines or infection remain robust against Omicron

In a new study, a team of researchers from multi-national institutions discovered that 70-80% of CD4 and CD8 T cell responses to spike were consistent across research groups. Moreover, although having far more mutations, the magnitude of Omicron cross-reactive T cells was comparable to that of the Beta and Delta variants.

SARS-CoV-2 Omicron variant highly resistant to vaccine-elicited and therapeutic antibodies

Researchers analyzed convalescent sera and sera from immunized individuals to demonstrate the evasion of antibodies by the SARS-CoV-2 Omicron variant.

TriSb92 as a potential inhibitor against SARS-CoV-2 variants including Omicron

New findings indicate that TriSb92 is a potent inhibitor of SARS-CoV-2 infection targeting a conserved site in the RBD of the spike, which is insensitive for immune escape mutations found in the relevant variants of concern, including Omicron

SARS-CoV-2 omicron variant may be less severe than the delta variant

A new study reveals that omicron infections in South Africa are associated with lower rates of hospital admissions and lower disease severity compared to beta and delta infections.

How much do mutations reduce vaccine effectiveness in the Omicron variant?

In new research, scientists from Adaptive Biotechnologies have been investigating the impact of spike protein mutations on vaccine efficiency for the Omicron variant. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Vaccine-induced T-cells vs. Omicron well preserved compared with all variants

A team of international scientists has recently revealed that T cell responses induced by coronavirus disease 2019 (COVID-19) vaccines are able to cross-recognize different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study is currently available on the bioRxiv* preprint server.

The use of monoclonal antibodies against infectious pathogens

Joshua Tan of the National Institute of Allergy and Infectious Diseases at the National Institutes of Health wrote a review article in the journal DNA and Cell Biology about the role of monoclonal antibodies and briefly described a study on bispecific antibodies that neutralize SARS-CoV-2.

30 Dec 2021

Clinical-grade soluble human ACE2 shown to inhibit SARS-CoV-2 Omicron variant

New study findings show that the clinical-grade soluble ACE2 effectively inhibits the SARS-CoV-2 Omicron variant, which proves the principle of an effective therapeutic approach against Omicron-driven COVID-19 infections.
