One California university has unified town and gown to fight covid. Why haven’t others?

Once a week, Lori Janich drives down the street from her office and partakes in an ongoing success story. Phone in hand to confirm her appointment, she strolls into the massive Activities and Recreation Center on the University of California-Davis campus, reaches a covid-19 testing station, swirls water in her mouth, spits into a tube, and leaves. Within a day, she receives her test result.

The CDC’s new guidelines on covid risk and masking elicit mixed feelings

When the Centers for Disease Control and Prevention last month unveiled updated covid-19 guidelines that relaxed masking recommendations, some people no doubt sighed in relief and thought it was about time.

How will mutations change the SARS-CoV-2 spike protein in the future?

A new Cells review discusses the factors that affect the function of the SARS-CoV-2 S protein and provides theoretical limits of this viral protein.

SARS-CoV-2 spike protein characteristics responsible for viral evolution in human hosts

Researchers directly compared the pre-fusion spikes of SARS-CoV-2 Alpha and Beta variants with the original Wuhan strain and the D614G-only variant.

Study explores immune escape mutations caused by prolonged viral shedding in immunocompromised COVID-19 patient

A new study examined a unique case of extended viral shedding in an immunocompromised patient that produced a series of SARS-CoV-2 immune escape mutations over a seven-month period.

Thermostable next-generation vaccine candidate against SARS-CoV-2 variants of concern studied in mice

Researchers developed a highly thermo-tolerant vaccine candidate that elicited high nAb titers in mice against several SARS-CoV-2 variants of concerns.

Comparative immunogenicity of reduced and standard BNT162b2 and mRNA-1273 boosters in CoronaVac vaccinees

Researchers compared the immunogenicity of the reduced and standard doses of the BNT162b2 and mRNA-1273 vaccine in adults immunized with two doses of the CoronaVac vaccine.

The NFL has been using an unproven measure to get players with covid back on the field fast

Two months before the Super Bowl, the omicron surge was decimating NFL rosters as players tested positive for covid-19. In mid-December, the NFL postponed a game between the Los Angeles Rams and the Seattle Seahawks because the Rams, who would go on to win the Super Bowl, had 29 players out with covid.

Recurrent mutations across the SARS-CoV-2 genome associated with long-term infections in immunodeficient patients

Researchers identified recurrent mutations in SARS-CoV-2.

Study finds Omicron BA.2 responsible for more but less infectious breakthrough infections

In a recent study posted to the medRxiv* pre-print server, researchers evaluated the severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron (B.1.1.529) infections between December 23, 2021, and February 20, 2022, in Qatar to understand how Omicron subvariants, vaccination, and prior infection status impacted these cases.

SARS-CoV-2 variant identification by RT-qPCR assays targeting mutations

In a recent study posted to the medRxiv* preprint server, researchers investigated the efficacy of diagnostic tests for identifying severe acute respiratory syndrome coronavirus (SARS-CoV-2) variants of concern (VOCs).

8 Mar 2022

Development of RT-qPCR assays for differentiating SARS-CoV-2 Omicron BA.1 and BA.2 variants

In a recent study posted to the medRxiv*preprint server, a team of researchers from Israel developed and validated novel reverse transcriptase - quantitative polymerase chain reaction (RT-qPCR) assays. The new assays enable the rapid and high throughput identification and differentiation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.1 and BA.2 variants.

French study shows COVID vaccine efficacy 94% against severe outcomes

A recent paper published on the medRxiv preprint server utilized data from three national databases containing an abundance of information on Covid-19 screening (SI-DEP), vaccination (VAC-SI), and hospitalizations (SI-VIC) in France to provide additional perspectives on vaccine effectiveness and its evolution over the year 2021 in the French context.
