Delayed second dose and third doses of the Oxford-AstraZeneca vaccine lead to heightened immune response

Research on the ChAdOx1 nCoV-19, also known as the Oxford-AstraZeneca vaccine, indicates that a long interval between first and second doses does not compromise the immune response after a late second dose. Additionally, a third dose of the vaccine continues to boost antibodies against SARS-CoV-2. The results were released in a preprint today. Delayed second dose The researchers

The European Commission has identified the first five drug candidates as part of a new strategy to select the preferred treatments for COVID-19 in the EU.

Among the five therapeutic candidates identified are Eli Lilly’s repurposed arthritis medicine Olumiant (baricitinib) and investigational antibody drugs for early-stage COVID-19. This includes Lilly’s bamlanivimab and etesevimab combination, Roche and Regeneron’s REGEN-COV (casirivimab and imdevimab), Celltrion’s regdanivimab and GlaxoSmithKline/Vir Biotech’s sotrovimab. The European Medicines Agency (EMA) is currently assessing an application for the extension of

Are COVID-19 vaccines effective against hospital admission with the Delta (B.1.617.2) variant ?

Vaccine effectiveness (VE) estimates against symptomatic disease with the Delta (B.1.617.2) variant have been recently reported. After a full course, VE reached 88% with the Pfizer/BioNTech BNT162b2 vaccine and 67% with the AstraZeneca ChAdOx1 AZD1222 vaccine. This provided important evidence that despite modest reductions in protection, vaccines remain effective against Delta. However, the very recent

Tokyo University of Science Scientists Find Drug Duo That May Cure COVID-19 Together

Preclinical experiments show that the drugs cepharanthine and nelfinavir may be effective treatments for COVID-19 While preventative care for COVID-19 has made much noise (with vaccines having rolled out in most countries), the soaring infection rates indicate the need for effective treatments. Using cultured cells to study SARS-CoV-2 infections, researchers at the Tokyo University of

Gene therapy appears more cost effective than current treatments for severe hemophilia B

St. Jude Children’s Research Hospital provides the first gene therapy manufacturing and distribution cost report for hemophilia B. A St. Jude Children’s Research Hospital analysis found a major gap between the cost to manufacture and distribute hemophilia B gene therapy and the $2 million-plus price reportedly under consideration for hemophilia gene therapy now in development. The study appeared

A new report on Pediatrics details 7 cases of myocarditis after COVID-19 vaccination

A new report takes a close look at seven teen boys who developed myocarditis after COVID-19 vaccination, each of whom had similar symptoms, timing and outcomes. While health officials investigate whether vaccination caused this condition, Judith A. Guzman-Cottrill, D.O., a corresponding author of the report, said she hoped the report would raise clinicians’ awareness to suspect

Pfizer-BioNTech vaccine recipients have lower antibody levels targeting the Delta variant first discovered in India

Levels of antibodies in the blood of vaccinated people that are able to recognise and fight the new SARS-CoV-2 Delta variant first discovered in India (B.1.617.2) are on average lower than those against previously circulating variants in the UK, according to new laboratory data from the Francis Crick Institute and the National Institute for Health Research

A Novel Form of Macrophage-based Immunotherapy Developed by Georgia State University Has the Potential to Revolutionize Cancer Treatment

A novel form of macrophage-based immunotherapy is effective at treating a broad spectrum of cancers, including those at advanced stages, according to a groundbreaking study led by Georgia State immunology professor Yuan Liu.  Liu’s treatment works by leveraging macrophages, specialized white blood cells involved in the detection and elimination of cancer cells and other pathogens. Macrophages also activate
