The World’s Supply Chain Isn’t Ready for a Covid-19 Vaccine – Bloomberg

Already stretched thin by the pandemic, freight companies face problems ranging from shrinking capacity on container ships and cargo aircraft to a lack of visibility on when a vaccine will arrive. Shippers have struggled for years to reduce cumbersome paperwork and upgrade old technology that, unless addressed soon, will slow the relay race to transport fragile vials of medicine in unprecedented quantities.

Rare mutations reveal more about COVID-19 and the immune system – Medical News Today

Scientists have found that four young males who experienced severe cases of COVID-19 in the Netherlands had rare mutations in the same gene on their X chromosome. The discovery sheds light on how the innate immune system mounts an early defense against the infection.

Doctors know that people with conditions such as hypertension, diabetes, and obesity, and older people are at greater risk of developing severe COVID-19, the illness caused by SARS-CoV-2.

Strategies Against SARS-CoV-2 by Studying Immune Response – Yale Scientific

While scientists have tirelessly worked to understand SARS-CoV-2’s mechanism of infection and pathogenesis, much is still unknown. To design an effective treatment or vaccine, researchers must both understand the mechanism by which a pathogen invades a cell, and have a way to measure the effectiveness of immune response. Since directly identifying the extent of the immune response to a vaccine is often difficult, “biomarkers”, or easy-to-measure benchmarks for different biological conditions, could help quantify immune response. To explore possible biomarkers for SARS-CoV-2 immunity, a team of researchers at the University of Melbourne studied the antibodies produced by immune cells of patients who recovered from COVID-19.

SARS-CoV-2 Virus Isolated From the Mastoid and Middle Ear – JAMA

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus and associated coronavirus disease 2019 (COVID-19) disease pandemic have rapidly spread around the world since December 2019. The high rate of droplet spread can endanger health care workers during procedures of the aerodigestive tract,1 particularly affecting otolaryngologists. Although there are no human data relating to the SARS-CoV-2 virus in the middle ear, the recommendations to mitigate these risks include precautions for middle ear and mastoid surgery1,2 because middle ear effusions have been shown to contain some non–SARS-CoV-2 coronaviruses.3 We present confirmation of SARS-CoV-2 colonization of the middle ear and mastoid in 2 of 3 patients.

NIAID-Led Study of COVID-19 mRNA Vaccine Supports Advance to Phase 3 Human Trials – Global BioDefense

Two doses of an experimental vaccine to prevent coronavirus disease 2019 (COVID-19) induced robust immune responses and rapidly controlled the coronavirus in the upper and lower airways of rhesus macaques exposed to SARS-CoV-2, report scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Some scientists are taking a DIY coronavirus vaccine, and nobody knows if it’s legal or if it works – MIT Tech Review

Nearly 200 covid-19 vaccines are in development and some three dozen are at various stages of human testing. But in what appears to be the first “citizen science” vaccine initiative, Estep and at least 20 other researchers, technologists, or science enthusiasts, many connected to Harvard University and MIT, have volunteered as lab rats for a do-it-yourself inoculation against the coronavirus. They say it’s their only chance to become immune without waiting a year or more for a vaccine to be formally approved.

A coronavirus vaccine may require boosters – here’s what that means – Medical Express

In the global race to contain the coronavirus pandemic, there is hopeful news on the vaccine front, with a number of potential candidates being developed and some promising early results. Based on what we know so far, it currently seems likely that most potential vaccines designed to protect against the SARS-CoV-2 virus that causes COVID-19 will require boosters, perhaps regularly. Why is this?

Drug discovery strategies for SARS-CoV-2 -Journal of Pharmacology and Experimental Therapeutics

COVID-19 is a novel disease caused by the SARS-CoV-2 virus that was first detected in December of 2019 in Wuhan, China and has rapidly spread worldwide. The search for a suitable vaccine as well as effective therapeutics for the treatment of COVID-19 is underway. Drug repurposing screens provide a useful and effective solution for identifying potential therapeutics against SARS-CoV-2. For example, the experimental drug remdesivir, originally developed for Ebola virus infections, has been approved by the FDA as an emergency use treatment for COVID-19. However, the efficacy and toxicity of this drug needs further improvements. In this review, we discuss recent findings on the pathology of coronaviruses and the drug targets for the treatment of COVID-19. Both SARS-CoV-2 specific inhibitors and broad-spectrum anti-coronavirus drugs against SARS-CoV, MERS-CoV, and SARS-CoV-2 will be valuable additions to the anti-SARS-CoV-2 armament. A multi-target treatment approach with synergistic drug combinations containing different mechanisms of action may be a practical therapeutic strategy for the treatment of severe COVID-19.

How is COVID-19 affecting America’s rich? – Brookings.edu

In the United States, as in many other countries, a battle has been unfolding between those who want to save lives and those who want to save livelihoods. Those who want to save livelihoods argue that the economic downturn is so massive that it is not only impacting the health of the economy but also health on a broader scale. As people lose health insurance, suffer growing anxieties, and face the risk of contracting the virus, a balance that optimizes the people’s well-being is difficult to attain. In uncertain times like these, granular data that provide accurate information on what is unfolding around the world are especially useful.
