Delta-like SARS-CoV-2 variants with enhanced transmissibility may cause a more severe pandemic

A SARS-CoV-2 variant with traits similar to that of the Delta variant-;enhanced transmissibility and an ability to infect people who had previous infections/vaccination-;will cause a more severe pandemic with more infections and breakthrough infections/reinfections than variants with either trait alone, according to a mathematical model created by researchers at Harvard T.H. Chan School of Public Health.

People taking immunosuppressant produce weaker, shorter-lived antibodies after COVID-19 vaccination

People who received two doses of the Pfizer COVID-19 vaccine while on TNF inhibitors -; a class of immunosuppressants used to treat rheumatoid arthritis and other autoimmune conditions -; generated less powerful and shorter-lived antibodies against the virus that causes COVID-19 than healthy people and those on other kinds of immunosuppressants, according to a study by researchers at Washington University School of Medicine in St. Louis.

Creating a timeline that details the earliest COVID-19 cases in Wuhan

In a Perspective, Michael Worobey provides an overview of the crucial events that occurred between December 2019 and January 2020 in Wuhan, China, creating a timeline detailing the earliest cases of COVID-19, their connections to the Hunan Market where live animals were sold, and the events that led to SARS-CoV-2's formal identification as a novel virus.

Risk of adverse pregnancy outcomes from SARS-CoV-2 likely lower than previously suggested

The risk of adverse pregnancy outcomes in women who tested positive for SARS-CoV-2 is likely lower than several earlier studies have suggested, a national study of all pregnant Swedish women tested for SARS-CoV-2 between March 2020 and January 2021 reports.

Can you take the COVID-19 and Influenza vaccines on the same day?

Scientists have conducted a substudy within a phase 3 UK trial and have reported the safety, immunogenicity, and efficacy of the NVX-CoV2373 COVID-19 vaccine when co-administered with licensed seasonal influenza vaccines.

Predicting the capacity of mammal species to become zoonotic SARS-CoV-2 hosts

Researchers identified a subset of species in which the threat of spillback infection appears the most significant due to location and increased contact with humans in areas with a high prevalence of SARS-CoV-2.

What happens after a campus suicide is a form of prevention, too

Ethan Phillips was 13 years old when he first heard the term "suicide contagion." It's the scientific concept that after one person dies by suicide, others in the community may be at higher risk.

Population-based risk compensation may have been a driving force in UK's COVID pandemic

The COVID-19 pandemic has irreversibly altered our lives in many ways. However, available COVID vaccines are effective against (symptomatic) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, hospitalizations, and even death. Despite a diminishing protective effect against infection and onward transmission after vaccination, and a slightly diminished effect with the Delta variant compared to the Alpha variant, protection against severe outcomes remains high.

UCLA study shows how COVID vaccination is critical to controlling the pandemic

A study currently available on the medRxiv* preprint server has demonstrated that the incidence and mortality rates of coronavirus disease 2019 (COVID-19) in the US can be significantly reduced at the population level by increasing vaccinate rates from 40% to 80%.

A nasal COVID vaccine using a weakened influenza vector

The authors of a new study, published on the bioRxiv* preprint server, constructed a COVID-19 nasal vaccine candidate by inserting a gene encoding the receptor-binding domain (RBD) of the spike protein of SARS-CoV-2, named CA4-dNS1-nCoV-RBD (dNS1-RBD) in a live attenuated influenza virus (LAIV) vector.
