CDC releases updated guidance for contingency and crisis management in healthcare settings

With the growing number of COVID-19 cases from the Omicron variant, and consistent with current understanding of the disease trajectory, CDC is releasing updated guidance for isolation and quarantine for healthcare workers, decreasing their isolation time after infection with COVID-19.

Researchers identify a key influenza epitope that can targeted for developing universal vaccines

A team led by scientists at Weill Cornell Medicine, Scripps Research and the University of Chicago has identified an important site of vulnerability on influenza viruses—a site that future influenza vaccines and antibody therapies should be able to target to prevent or treat infections by a broad set of influenza strains.

Children produce a much more robust antibody response to a SARS-CoV-2 infection than 18+

Scientists compared receptor binding domain antibodies and SARS-CoV-2 neutralizing antibodies in children and adults.

Omicron has enhanced infectivity that is only weakly neutralized by vaccination or prior infection

Scientists used virus-like particles and found that Omicron showed increased infectivity, relative to the B.1 and B.1.1 strains, which was similar to the Delta variant.

Researchers report loss of antibody potency against SARS-CoV-2 Omicron variant

Researchers find that vaccine-mediated protection against SARS-CoV-2 is significantly reduced against the Omicron variant.

Exploring immunity and severe disease caused by the SARS-CoV-2 Omicron variant

A new study describes the findings of a seroprevalence survey intended to establish the infection rates and the incidence of severe COVID-19 through December 15, 2021, in Gauteng, a crowded province that compresses a quarter of the country’s people into less than 2% of its area.

Assessing the clinical severity of the SARS-CoV-2 Omicron variant

A recent preprint examines the proportion of Omicron infection and the risk of severe disease with this variant of SARS-CoV-2.

Watch: One city’s effort to raise vaccination rates among Black residents

About 72% of Americans have received at least one dose of a covid-19 vaccine. During much of the vaccine rollout, Hispanic and Black Americans have been less likely than white Americans to get vaccinated.

Study reports that children develop sustained cross-reactive adaptive immunity against coronaviruses

A new study shows that both antibody and cellular arms of the adaptive immune response against SARS-CoV-2 are displayed strong, sustained, and cross-reactive against other coronaviruses, in young children than the immune responses in adults.

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.

New allocation model to optimize the distribution of COVID-19 vaccines, treatments

Lulu Kang, associate professor of applied mathematics at Illinois Institute of Technology and a team of researchers from the University of Illinois Chicago put a new twist on traditional resource allocation models to optimize the distribution of COVID-19 vaccines, treatments, testing supplies, and other related resources, publishing their findings, "Fair and Diverse Allocation of Scarce Resources," in Socio-Economic Planning Sciences.

Decline in protection against SARS-CoV-2 Omicron in prior infected and fully vaccinated

In a recent study posted to the medRxiv* preprint server, researchers investigated the distribution of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta and Omicron variants among coronavirus disease 2019 (COVID-19) positive individuals who were either naive, fully vaccinated, or had a previous infection to further investigate possible escape from vaccine- or infection-induced immunity by Omicron compared to Delta.

World leaders meet to discuss about COVID-19 vaccines, therapeutics and diagnostics

The heads of the International Monetary Fund, World Bank Group, World Health Organization and World Trade Organization held high-level consultations with Gavi and UNICEF on 17 December, 2021 aimed at increasing the use of COVID-19 vaccines and other critical medical countermeasures in low-income (LIC) and lower middle-income (LMIC) countries and supporting countries to be better prepared, resourced, and ready to roll out vaccines.

T-cell response to Omicron after an mRNA COVID vaccine booster

In a recent prospective observational study posted to the medRxiv* preprint server, researchers determined Omicron variant-associated T cell responses before and after a third dose of messenger ribonucleic acid (mRNA) vaccination against coronavirus disease (COVID-19) in anti-CD20-treated multiple sclerosis (MS) patients.

More breakthrough infections but less severe COVID-19 with Omicron

In a recent study posted to the bioRxiv* pre-print server, an international team of researchers reported the occurrence of coronavirus disease 2019 (COVID-19) breakthrough infections (BTIs) among health care workers (HCWs) participating in a phase III vaccine trial in Sisonke, South Africa.
