Why does COVID-19 hit men harder than women? Is the disparity in mortality rates due to male hormones or an underlying difference in the male versus female immune system?
Drugs and vaccines to fight the coronavirus are already in clinical trials. It is important to understand the difference between each step in this process as efforts to fight COVID-19 continue.
Africa needs to be better prepared to deal with future pandemics. That should start with a re-assessment of how countries invest in – and support – local research.
Army physicians are turning to drugs approved for other conditions or newly developed treatments such as the antiviral Remdesivir to treat infected personnel.
Vaccine development is usually a long process. The coronavirus pandemic is forcing researchers to innovate and test potential vaccines faster than ever before.
A vaccine historically used to prevent tuberculosis is now among the contenders for a COVID-19 vaccine. So what is the BCG vaccine and why might it work against coronavirus?
Preliminary results from a US trial show remdesivir may help in treating COVID-19. But the findings haven’t been peer-reviewed, and the results from other clinical trials have shown little effect.
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.
New research claiming that people do not need to reduce their consumption of red and processed meat says more about the conduct and evaluation of research than it does about beef.
Clinical trials are used to establish that medicines work. But these don’t take into account the genetic differences between us that can mean very different outcomes for different patients.
