Repeat infection following COVID-19 recovery may not pose risk to close contacts

Researchers in China have conducted a study suggesting that people who have recovered from coronavirus disease 2019 (COVID-19) may not pose a risk to close contacts if they become reinfected with the causative agent severe acute respiratory syndrome coronavirus (SARS-CoV-2).

SARS-CoV-2 spike deletion mutations may evade current vaccine candidates, study finds

A thought-provoking new study reports that the anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike antibodies elicited by natural infection may not be able to neutralize emerging strains that display deletion mutations in their genomic RNA.

Nasal dryness could be an early warning sign of COVID-19

A new study published by an international team of researchers on the preprint medRxiv* server in November 2020 details the nasal symptoms that are associated with anosmia and ageusia (loss of smell and taste) in coronavirus disease 2019 (COVID-19), including the early warning signs of infection.

Modified SARS-CoV-2 receptor-binding domain could increase vaccine efficacy, says study

A team of researchers from the USA and China have engineered a receptor-binding domain (RBD) that they claim improves the immunogenicity of multivalent SARS-CoV-2 vaccines. Their study, which was released on the bioRxiv* in November 2020, may help advance even more efficacious SARS-CoV-2 vaccine candidates in the future.

Researchers develop recombinant SARS-CoV-2 model to aid vaccine and antiviral research

Researchers have developed a fluorescent reporter gene-bearing recombinant form of SARS-CoV-2, which is capable of replication.

Chicago seroprevalence study shows COVID-19 cases 16 times higher than currently predicted

A startling new case study of Chicago, led by a team of researchers at Northwestern University in Illinois, USA, suggests a 16-fold higher incidence of SARS-CoV-2 infection than previously thought. This is judging from seroprevalence (antibody presence blood testing) figures, rather than the number of RT-PCR-positives reported there (via swab sample testing of symptomatic patients).

Compounds in traditional Chinese medicine herbs may inhibit SARS-CoV-2 infection

Using computational methods, a team of researchers identified three compounds in traditional Chinese medicine that could be used against SARS-CoV-2.

FDA schedules meeting to discuss emergency use authorization of COVID-19 vaccine from Pfizer

Today, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) for casirivimab and imdevimab to be administered together for the treatment of mild to moderate COVID-19 in adults and pediatric patients (12 years of age or older weighing at least 40 kilograms [about 88 pounds]) with positive results of direct SARS-CoV-2 viral testing and who are at high risk for progressing to severe COVID-19.

Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance

For COVID-19 Surveillance, Test Frequency and Turnaround Time Are Paramount, Modeling Suggests Speed of test results and frequency of testing are paramount for effective COVID-19 surveillance, suggests a new study that modeled trade-offs in test sensitivity, test frequency, and sample-to-answer reporting time, in select scenarios.

SARS-Cov-2 antibodies are detected up to 3 months after infection, shows study

A new study in health care workers led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by "la Caixa" Foundation and the Hospital Clínic of Barcelona, shows that IgA and IgM antibodies to SARS-CoV-2 decay quickly, while IgG antibody levels are maintained for at least three months after infection.

Study suggests neutralizing SARS-CoV-2 antibodies offer protection against reinfection

A new study published in November 2020 on the preprint server medRxiv* indicates that the chances of symptomatic infection are indeed much lower among the population with antibodies to the virus.
