Purifying selection drives time-dependency of short-term mutation rates in SARS-CoV-2 and pH1N1 influenza

A new paper, available on the medRxiv* preprint server, indicates the adaptation undergone by the SARS-CoV-2 molecular genome and the pH1N1 influenza pandemic strain during the first year of their spread, separately. Using statistical and phylogenetic skills, the researchers present a picture of the emergence, rates of change, and of growth, of these two viruses as time passes.

SARS-CoV-2 Q493R protein mutation shows resistance to monoclonal antibodies

The Centers for Disease Control and Prevention (CDC) issued a letter detailing a case of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in an immunocompromised patient who did not respond well to monoclonal antibody treatment. The resistance to treatment stemmed from an escape mutation on the spike protein known as Q4923R.

Israeli study of breakthrough infections following full BNT-Pfizer vaccination, 40% immunocompromised

Severe forms of coronavirus disease (COVID-19) linked to high mortality rates might arise in a minority of fully-vaccinated individuals with many co-occurring medical conditions, finds a recent study by Israeli researchers published in the journal Clinical Microbiology and Infection.

New York City SARS-CoV-2 breakthrough cases predominantly Alpha and Iota variants

While Delta (B.1.617.2) has overtaken Alpha (B.1.1.7) as the dominant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant in the United States, Alpha remained a force to be reckoned with in New York City earlier this year. New research published on the preprint medRxiv* server details breakthrough infections in vaccinated and unvaccinated individuals living in New York City.

Mother-to-baby SARS-CoV-2 transmission in pregnancy possible but rare, says study

A new meta-analysis, released on the medRxiv* preprint server, suggests that, though possible, the virus is rarely transmitted to the newborn in real life. A scientific brief from the World Health Organization (WHO) in February 2021 describes three mechanisms by which the virus might be transmitted from the mother to the fetus or newborn.

COVID-19 vaccination may be stemming evolution of “fitter” SARS-CoV-2 variants

Researchers in the United States and India have presented the first known evidence that the rollout of coronavirus disease 2019 (COVID-19) vaccination is restricting the evolutionary and immune escape pathways accessible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Janssens’ COVID-19 vaccine effective against SARS-CoV-2 Delta variant

Researchers in the Netherlands have conducted a study showing that Janssen’s Ad26.COV2.S coronavirus disease 2019 (COVID‐19) vaccine was effective against variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among eight individuals.

New blood test can accurately detect 50 types of cancer before symptoms emerge

Final results from a study of a blood test that can detect more than 50 types of cancer have shown that it is accurate enough to be rolled out as a multi-cancer screening test among people at higher risk of the disease, including patients aged 50 years or older, without symptoms.
