Further tests are needed but a trial showed that, when compared against placebo treatment, those given the drug had a 79% lower risk of developing severe disease.
The race is on to develop a vaccine for the COVID-19 coronavirus. Australian researchers are leading several major clinical trials that might help bring an end to the deadly disease.
Researchers are central to any country’s science preparedness, especially in the face of pandemics.

Amyotrophic lateral sclerosis, Lou Gehrig's disease, is a crippling, progressive neurodegenerative disease for which there is no cure. Now it seems that a diabetes drug may help some cases.
Vaccinologists have not focused their research on tailoring vaccines to induce robust immune responses in the elderly.
Immunosenescence — the decline of immune system function with age — means that vaccines are not as effective in older adults, the demographic most susceptible to many diseases, including COVID-19.
The experimental vaccine stimulates the creation of antibodies. Now we need to show that these effectively protect us from the coronavirus.
Loneliness affects one in three people in the industrialized world, with racialized groups disproportionately bearing the burden.
Pluralism — the active process of inclusion — could reduce disparities in some of the most pressing health issues of our time.
The lower the vaccine’s effectiveness, the more likely social distancing in some form may still be necessary.

Severe scrutiny of two major papers, including one about the effectiveness of hydroxychloroquine, is part of science's normal process of self-correction.
The scope and length of vaccine testing experiments usually mean decade-long timelines for development.
It usually takes 10 years for a new vaccine to complete clinical trials, but we've been promised a COVID-19 vaccine in 12 to 18 months. Even if such fast-tracked development is possible, is it wise?
Laboratories around the world are working round the clock to find treatments or a vaccine for COVID-19.

The FDA has sped up its approval process for coronavirus treatments, creating a new division to expedite the regulatory process. But is safety being sidelined for speed?
There is a growing call for so-called challenge trials to speed up vaccine development.
Early clinical trials into ginseng, rhubarb and rice paved the way for testing coronavirus treatments today.
Finding a cure for the coronavirus requires more than anecdotal evidence.
