Some things about COVID-19 still don't add up.
The science is not so clear cut.
Some people's immune systems aren't able to stop foreign invaders, such as COVID-19, as well as the rest of the population. There are many reasons for this, including illness, medications and age.
Exercising indoors is beneficial for our immune system.
Though it was previously thought vigorous exercise could suppress immune function, research shows that most forms of regular exercise can help your immune system to work its best.

OK, we're all getting a little stir-crazy from staying at home. But is a mixed drink with vitamins added really something we should consider?
Wouldn’t it be nice if getting a vaccine was a simple as putting on a Band-Aid?
University of Pittsburgh researchers are developing a vaccine patch for COVID-19 that is as easy to apply as a Band-Aid.

To boost your immune defenses against corona and other viruses, one of the most effective things you can do is maintain your natural circadian rhythms. Here's how to do that.

The new coronavirus, SARS-CoV-2, spreads faster than the H1N1 influenza virus and is much deadlier. SARS-CoV-2 is particularly skilled at keeping cells from calling out for help.

Before a vaccine is available to teach your immune system to ward off the coronavirus, maybe you can directly use molecules that have already fought it in other people.
A test that detects antibodies against the coronavirus behind COVID-19 would reveal those people who have already encountered the virus - and therefore who might be ok to resume normal life.

Traditional vaccines can take years to create. Rather than immunizing people with viral proteins, the new approach gives the molecular instructions that allows the body to make its own vaccine.
Stress about the coronavirus pandemic can actually increase your risk of infection, but exercise can alleviate the immune system’s stress response. Above, a lone jogger in Ottawa, on March 17, 2020.

The immune system can respond to stress in ways that harm health. But there's a stress-buster that can help keep you calm and healthy: exercise.

Different demographics are more or less vulnerable to serious complications from the coronavirus. A virologist explains the aging-related changes in how immune systems work that are to blame.
If your child has accidentally eaten something you thought they were allergic to, but doesn't have a response, they may have grown out of their food allergy. Here's the safest way to check.
It’s an age-old battle between parents and kids.
Leaving your coat at home on a cold winter day doesn't automatically mean you're going to get sick. But it could make you more susceptible to germs.
Increased scientific understanding of the role microbes play in humans and other animals has led to the development of probiotics to improve heath.
From dietary supplements to poop transplants, probiotics are now a multi-billion dollar market.
Researchers discovered a cream could stop the spread of deadly viruses from mosquitoes.
The cream was found to boost the body's anti-viral immune response, stopping mosquito-borne viruses in their tracks.
