Whether a coronavirus vaccine involves a live virus or a carrier organism, it will probably require more than one injection. But that’s not a bad thing.
Children are at risk of getting sick from coronavirus and need to practice social distancing and mask wearing too.

Ideally everyone could get tested frequently for the coronavirus. No state is close to achieving this, but some are doing better than others. What are the challenges in meeting demand for testing?

A team of researchers from Indiana University performed random testing for SARS-CoV-2 across the state. The results offer some of the most accurate data to date about important aspects of the virus.
On a family camping trip over the Australia Day long weekend, I sat in a tent with my laptop, designing New South Wales’ first genomic sequencing test for COVID-19.
COVID-19 antibody tests can’t replace the use of PCR tests in people showing symptoms. But they can help test people who may be infected and asymptomatic.
Cardiovascular disease is the leading source of death worldwide.

Scientists have developed and tested a new anti-clotting drug in mice that shows promise for treating heart attacks and stroke. It may also prove useful for COVID-19.
Infection fatality rate is simply the number of deaths divided by the number of infections, but finding those numbers is harder than it might seem.

The percentage of people who die from a coronavirus infection is an important number for public health experts to know. Recent estimates now put it at 0.65%, far lower than initially thought.

As the pandemic drags on, uncertainty and fears about health and safety mix with confusion and challenges tied to re-opening society. You need flexibility when picking your coping strategies.
Vaccine development usually spans a number of decades. This is because there’s a need to understand the mechanisms of protection against the pathogen, and to minimise adverse reactions.
COVID-19 has been linked to neurological problems in those with severe disease.

As if the symptoms of COVID-19 were not disturbing enough, physicians have noted a rare neurological condition that emerges during some severe cases of this viral infection.
239 scientists have penned an open letter to the WHO arguing COVID-19 likely spreads through the air. But what is airborne transmission, and how strong is the evidence COVID-19 spreads this way?
Daily deaths from COVID-19 have rarely been below 600 in the U.S. since March.
