The first COVID-19 vaccine for the UK, developed by Pfizer/BioNTech, has been given approval for use following a thorough review carried out by the Medicines and Healthcare products Regulatory Agency (MHRA).

The decision by the UK regulatory authority was made with advice from the Commission on Human Medicines (CHM), the government's independent expert scientific advisory body.

A computational model of a human lung cell has been used to understand how SARS-CoV-2 draws on human host cell metabolism to reproduce by researchers at the University of Warwick. This study helps understand how the virus uses the host to survive, and enable drug predictions for treating the virus to be made.

The lives of patients hospitalised with COVID-19 are being saved by doctors who are using an existing medical treatment at an earlier stage.

Dr Luigi Sedda of Lancaster University analysed the results from the team at Wrightington, Wigan and Leigh Teaching Hospitals NHS Trust (WWL). Their research has now been published in the prestigious medical journal BMJ Respiratory Open.

Today, the European Commission approved a sixth contract under the EU Vaccines Strategy, this time with the pharmaceutical company Moderna. The contract provides for the initial purchase of 80 million doses on behalf of all EU Member States, plus an option to request up to a further 80 million doses, to be supplied once a vaccine has proven to be safe and effective against COVID-19.

A new therapy for influenza virus infections that may also prove effective against many other pathogenic virus infections, including HIV and COVID-19, has been developed by Purdue University scientists.

In an average year, more than 2 million people in the United States are hospitalized with the flu, and 30,000 to 80,000 of them die from the flu or related complications.

The surface of the SARS-CoV-2 virus is studded with spike proteins. The virus needs these in order to dock onto proteins (ACE2 receptors) on the surface of the host cell. Before this docking is possible, parts of the spike protein have to be cleaved by the host cell's enzymes - proteases.

Results from an early-phase randomised clinical trial of a Chinese vaccine candidate based on the inactivated whole SARS-CoV-2 virus (CoronaVac) are published in The Lancet Infectious Diseases journal, finding the formulation appears safe and induces an antibody response in healthy volunteers aged 18 to 59 years.
