Several vaccines are in Phase 3 trials. So when will we know whether any of these will protect against COVID-19?
Eating lots of fruits and vegetables will boost the immune system.

Many of us don't get an adequate amount of nutrients.
Not all vaccines will work so well in all people. That's why we need large-scale clinical trials to test candidate vaccines in thousands of people.
Steroids could do more harm than good in patients with milder cases of COVID-19.

Three new studies show corticosteroids can reduce deaths in critically ill COVID-19 patients. But what about other patients?
Introducing healthy genes to replace defective ones is the essence of gene therapy.
The immune system is trained to destroy viruses, even when they carry therapeutic cargo as is the case in gene therapy. Now researchers have figured out how to dial down the immune response.

If antibody levels drop dramatically after an infection, what does that mean for immunity? An expert explains how B and T cells contribute to immunity and why antibodies don't tell the full story.

Scientists were not surprised by reports on coronavirus reinfection; the lack of symptoms on reinfection is encouraging.
There are currently no permanent treatments for most patients with inflammatory bowel disease.

Researchers discover clues to the origin of inflammatory bowel disease and a possible strategy for treatment.
Some people's blood can mount an immune response against SARS-CoV-2, even if those blood samples were taken from before the COVID-19 pandemic started.
The complex interactions that maintain group health inside a bee hive offer lessons for humanity during pandemics.
Life in a honey bee hive is all about cooperating for the collective good.
It’s possible that changes to the immune system during pregnancy protect parent and child from COVID-19.
Your immune system changes when you are pregnant, and this may help protect you and your child from COVID-19 – but we need more research to understand this better.
Some people who have never had COVID-19 have the antibodies to fight it – possibly from an earlier infection with a different coronavirus.
More and more studies are revealing the cognitive effects of COVID-19.

Many patients suffering from COVID-19 exhibit neurological symptoms, from loss of smell to delirium to a higher risk of stroke. Down the road, will COVID-19 survivors face a wave of cognitive issues?
We're cleaning and washing our hands perhaps more than we ever have before. But suggestions that all this this extra hygiene could weaken our immune systems are unfounded.
Children are at risk of getting sick from coronavirus and need to practice social distancing and mask wearing too.

Research shows that children can become infected with the coronavirus and spread it to others. Though rare, some kids do become severely ill and a few have died from COVID-19.
It's hard to discuss COVID without referring to white blood cells. Here is a primer on the two you need to know about.
Duck decoys lure real ducks within range of hunters. Nanoparticles that look like cells serve as both decoys and hunters to ensnare virus particles.
Nanoparticles dressed up in cell membranes snag SARS-CoV-2 virus particles before they reach human cells.
The cutting-edge tools could greatly expand our understanding of different species' immune systems, and also help humans prepare for future disease outbreaks.
Is coronavirus over in some cities?
There is speculation about whether a population can achieve some sort of immunity to the virus with as little as 20% infected.
For those who have suffered from COVID-19, do their antibodies guarantee immunity from subsequent disease?

If you have had COVID-19 already, are you protected from another bout of the illness? And is the presence of antibodies in your blood a guarantee of immunity?
