Shares of Inovio climbed in trading after the company announced its DNA vaccine candidate for Covid-19 induced a robust T-cell response against multiple variants of the SARS-CoV-2 virus.

The first study to directly compare immune reactions between Pfizer’s and AstraZeneca’s Covid-19 vaccines found strong and broadly similar antibody responses in over-80-year-olds after a first dose of either shot, scientists said on April 14.

A joint China-World Health Organization (WHO) study into Covid-19 provided no credible answers about how the pandemic began, and more rigorous investigations are required – with or without Beijing’s involvement, a group of international scientists and researchers said on April 7.

Emergent BioSolutions’ Phase III trial of SARS-CoV-2 Immune Globulin Intravenous (Human) (COVID-HIG) to treat hospitalized patients with COVID-19 showed that the addition of the treatment to Gilead Sciences’ remdesivir did not provide clinical benefit compared to standard of care plus placebo in hospitalized adult COVID-19 patients with symptoms for less than 12 days.

A joint WHO-China study on the origins of Covid-19 says the virus was probably transmitted from bats to humans through another animal, and that a lab leak was “extremely unlikely” as a cause, the Associated Press reported on March 29.

A recent study published in Science Translational Medicine shows that a new flu vaccine appears to protect monkeys against influenza strains that are likely to cause a global pandemic, giving researchers hope that this vaccine could hold the key to providing a future universal flu vaccine for humans.

Merck entered into multiple agreements to support efforts to expand manufacturing capacity and supply of SARS-CoV-2/Covid-19 medicines and vaccines.

LightDeck Diagnostics was awarded a $5.65 million contract from the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the US Department of Health and Human Services (HHS), to develop an rapid antigen test to detect SARS-CoV-2.

All the Covid-causing virus circulating in the world could easily fit inside a single cola can, according to a calculation by a British mathematician whose sum exposes just how much devastation is caused by minuscule viral particles.
