The transmission dynamics of SARS-CoV2 Omicron variant

In a recent study posted to the medRxiv* preprint server, researchers developed a coronavirus disease (COVID-19) model-inference system in South Africa to determine transmission dynamics and immune evasion associated with severe acute respiratory syndrome-associated coronavirus disease (SARS-CoV-2) Omicron variant.

Factors associated with having data on SARS-CoV-2 infection and COVID-19 severity

Researchers utilized pre-pandemic information from two UK-based observational population studies to investigate predictors of selection into analytic subsamples in observational studies on SARS-CoV-2 infection and on COVID-19 severity.

Containing a Nipah virus outbreak amidst the COVID-19 pandemic

A new study deals with a single case of Nipah virus that occurred in 2021, with no discoverable chain of transmission, apparently ending with the death of the index patient in Kerala.

SARS-CoV-2 infection risks increase with time in fully vaccinated adults

A recent study describes the association between time elapsed since the second dose of the Pfizer-BioNTech BNT162b2 vaccine and risk of COVID-19.

Longer interval between COVID-19 mRNA vaccine doses leads to stronger immune response

The first peer-reviewed study in North America examining the timing between the first and second doses of COVID-19 mRNA vaccines shows that a longer dose interval leads to a stronger immune response. The study is funded by the Government of Canada through its COVID-19 Immunity Task Force.

Natural COVID-19 infection offers protection from gamma and delta variants of SARS-CoV-2

Natural infection with COVID-19 offered protection from reinfection when the gamma and delta variants predominated, according to a new University of Michigan study that also provides levels of antibodies needed to protect against reinfections.

Immunity found 6 months after SARS-CoV-2 infection in children

A new study suggests that infection-induced antibodies persist, providing protection for at least six months.

Study finds no evidence to support favipiravir use in mild or asymptomatic COVID-19 patients

Researchers conducted a Phase II randomized placebo-controlled, double-blinded trial between July 8, 2020, and March 23. 2021.

Limited immune responses three months after Pfizer-BioNTech vaccination among elderly

In this study, published on the medRxiv* preprint server, the humoral response to SARS-CoV-2 was assessed before and after three months of administration of the BNT162b2 mRNA COVID-19 vaccination (Pfizer-BioNTech). In addition, elders' humoral responses were compared to those of a younger group, and a functional neutralization experiment against the Wuhan-Hu-1 (WH1) virus and the Delta variant was carried out.

Study finds no increased risk of severe COVID-19 in immunocompromised children in UK

Researchers conducted a prospective study to describe the incidence and clinical spectrum of SARS-CoV-2 infection in a UK-wide cohort of immunocompromised children.

Sheep at low-risk for infection with SARS-CoV-2

A team of scientists from the US has recently evaluated the susceptibility of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in sheep. The findings reveal that sheep are generally less susceptible to SARS-CoV-2 infection. However, the susceptibility is relatively higher for the alpha variant of the virus. The study is currently available on the bioRxiv preprint server.
