Researchers seek to repurpose an existing manufacturing platform to produce a COVID-19 vaccine

In the search for a rapid COVID-19 vaccine, researchers are modifying a method using the chemical riboflavin now used to prevent disease transmission during blood transfusions.

Few clinical trials are done in Africa: COVID-19 shows why this urgently needs to change

More countries on the African continent must urgently get involved in clinical trials so that the data collected will accurately represent the continent at a genetic level.

Here’s how scientists are tracking the genetic evolution of COVID-19

The SARS-CoV-2 virus that causes COVID-19 is constantly mutating. What do these mutations reveal about this virus’s evolution? And will this knowledge help us to develop a long-lasting vaccine?

What the coronavirus does to your body that makes it so deadly

The new coronavirus, SARS-CoV-2, spreads faster than the H1N1 influenza virus and is much deadlier. SARS-CoV-2 is particularly skilled at keeping cells from calling out for help.

Coronavirus: A new type of vaccine using RNA could help defeat COVID-19

Traditional vaccines can take years to create. Rather than immunizing people with viral proteins, the new approach gives the molecular instructions that allows the body to make its own vaccine.
