Developing an effective universal influenza vaccine against influenza virus with highly conserved antigenic epitopes could induce a broad-spectrum immune response to prevent infection.

(An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells. For example, the epitope is the specific piece of the antigen to which an antibody binds. See picture1)

Vaccination is the most effective way to prevent influenza virus infection. Current influenza vaccines are based on induction of protective antibodies against the viral surface hemagglutinin (HA) protein, which can effectively neutralize the influenza virus and significantly reduce morbidity and mortality. However, owing the variability of HA, vaccine strains need to be changed every year.

This is pretty cool:

The vaccine targets the novel coronavirus’s Achilles’ heel, its Receptor Binding Motif (RBM), a critical structure that enables the virus to bind to and infect a target cell. According to Prof. Gershoni, the vaccine would reconstruct the coronavirus’s RBM, a tiny feature of its “spike” protein. Though the virus uses many different proteins to replicate and invade cells, the “spike” protein is the major surface protein that it uses to bind to a receptor — another protein that acts like a doorway into a human cell. After the spike protein binds to the human cell receptor, the viral membrane fuses with the human cell membrane, allowing the genome of the virus to enter human cells and begin infection.

Tel Aviv University’s Professor Jonathan Gershoni has been awarded a US patent for a novel coronavirus vaccine design.

A low-cost, easy-to-build non-invasive ventilator aimed at supporting the breathing of patients with respiratory failure performs similarly to conventional high-quality commercial devices, according to new research published in the European Respiratory Journal.

Non-invasive ventilators are used to treat patients with breathing difficulty and respiratory failure, a common symptom of more severe coronavirus disease. Non-invasive ventilation is delivered using facemasks or nasal masks, which push a set amount of pressurized air into the lungs. This supports the natural breathing process when disease has caused the lungs to fail, enabling the body to fight infection and get better.

The research paper provides a free to replicate, open-source description for how to build the ventilator. The researchers say the prototype ventilator could support treatment of coronavirus and other severe respiratory diseases in low-income regions or where ventilator supplies are limited.

I want your opinions on this:

ANTANANARIVO, Madagascar — The president of Madagascar Andry Rajoelina has officially launched a local herbal remedy claimed to prevent and cure the novel coronavirus. “Tests have been carried out — two people have now been cured by this treatment,” Rajoelina told ministers, diplomats and journalists at the Malagasy Institute of Applied Research (IMRA), which developed the beverage.

Announcing the brew, Andry Rajoelina drinks a bottle of ‘Covid-Organics,’ which he says has already cured 2 people; scientists warn of risks from untested herbal concoctions.
