How does your body's immune system fight COVID-19?
Australian researchers have found that our immune systems respond to this coronavirus in the same way as to influenza.
The immune cells that emerge in the blood before patients recover from COVID-19, are the same cells we see in people before they recover from the flu.
Researchers at the Peter Doherty Institute for Infection and Immunity were able to work this out by looking at multiple blood samples from one of Australia's first patients diagnosed with COVID-19.
Importantly, the research published in Nature Medicine is "the first paper that shows the body can give immunity and fight back and recover", researcher Carolien van de Sandt said.
Based on their experience with influenza patients, it also allowed the researchers to accurately predict how long the patient would take to recover from COVID-19.
But it's still too early to tell whether contracting coronavirus once would give you immunity to prevent you catching it again.
Could existing drugs treat COVID-19 infections?
Early signs are promising, after Australian researchers this week revealed they are ready to begin clinical trials of a potential treatment for COVID-19 — using two existing drugs.
The drugs in question are an older HIV drug and an anti-malaria drug called chloroquine, which is rarely used now as the malaria pathogen has become resistant to it.
This phase of the trial could be as short as three months, Professor Paterson said, but it would take longer to roll the treatment out in the community, if it did prove effective.
Worldwide, Chinese doctors are completing clinical trials looking at the effectiveness of a combination of two HIV drugs, lopinavir and ritonavir, at treating COVID-19, New Scientist reported.
They are also soon to start testing a drug called remdesivir which was originally developed for Ebola.
When will we get a vaccine for COVID-19?
Lots of different groups around the world are working on possible COVID-19 vaccines.
"There are now 15 potential vaccine candidates in the pipeline globally using a wide range of technolog[ies]: mRNA, DNA, nanoparticle, synthetic and modified virus-like particles," said microbiologist Ian Henderson of the University of Queensland.
The US National Institutes of Health announced that they have funded phase 1 clinical trials of a potential COVID-19 vaccine, called mRNA-1273, which began this week.
The vaccine was able to be brought to clinical trials so quickly because researchers had already been working on a vaccine to protect against another coronavirus, which causes Middle East respiratory syndrome (MERS).
While results from this first trial may be available within three months, it will still take at least a year and likely longer for a resulting vaccine to be widely available to the public.
