High effectiveness of mix-and-match COVID-19 vaccines

People who had received a first dose of the Oxford-AstraZeneca COVID-19 vaccine and received an mRNA vaccine for their second dose had a lower risk of infection compared to people who had received both doses of the Oxford-AstraZeneca vaccine. This is shown in a nationwide study performed by researchers at Umeå University, Sweden.

One coronavirus vaccine may protect against other coronaviruses

Northwestern Medicine scientists have shown for the first time that coronavirus vaccines and prior coronavirus infections can provide broad immunity against other, similar coronaviruses. The findings build a rationale for universal coronavirus vaccines that could prove useful in the face of future epidemics.

Vaccines effective against most SARS-CoV-2 variants

Two of the commonly used coronavirus vaccines provide protection against multiple variants of the virus that causes COVID-19, including the highly infectious Delta variant, a new Yale study has found.

The findings, published Oct. 11 in the journal Nature, also show at those infected with the virus prior to vaccination exhibit a more robust immune response to all variants than those who were uninfected and fully vaccinated.

Scientists discover a highly potent antibody against SARS-CoV-2

The newly identified antibody was isolated using lymphocytes from COVID-19 patients enrolled in the ImmunoCoV study being carried out by CHUV’s Service of Immunology and Allergy. This antibody is one of the most powerful identified so far against SARS-CoV-2. Structural characterization of the antibody indicates that it binds to an area that is not subjected to mutations of the spike protein.

mRNA COVID vaccines highly effective at preventing symptomatic infection in health workers

COVID-19 vaccines are highly effective in preventing symptomatic illness among health care workers in real-world settings.

The study, published in the New England Journal of Medicine, found that health care personnel who received a two-dose regimen of Pfizer-BioNTech vaccine had an 89% lower risk for symptomatic illness than those who were unvaccinated.

New drug combination effective against SARS-CoV-2 infection

More countries with greater resources are opening up for a more normal life. But COVID-19 and the SARS-CoV-2 virus are still a significant threat in large parts of the world.

The lack of medicines that are effective, easy to distribute and easy to obtain are a significant part of the problem.

Discovery of mechanics of drug targets for COVID-19

A team of international researchers, including McGill Professor Stéphane Laporte, have discovered the working mechanism of potential drug targets for various diseases such as cancer, rheumatoid arthritis, and even COVID-19. The findings published in Molecular Cell uncover the inner workings of cell receptors that are involved in cancer progression and inflammatory diseases.
