The appearance of hives can vary with skin color.

Hives are an allergic reaction and can sometimes be a sign of a more serious immune response.
The immune system usually stays dormant in the lungs in times of health.

While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.
Consuming an ample supply of fresh fruits and vegetables is still a tried and true way of getting vitamins and minerals and achieving lasting health benefits.

Despite the popular belief that vitamin E and beta carotene supplements help prevent heart disease and cancer, the latest research suggests they do not – but the supplements do have potential risks.
Immunosenescence, or immune aging, can lead to less effective responses to vaccines and greater vulnerability to invading pathogens.

While the immune system naturally gets weaker with age, social stressors like trauma and discrimination can hasten immunosenescence.
With mask mandates and vaccine requirements lifting, public health information remains crucial so people can weigh their own COVID-19 risks.

To help people make informed decisions about ongoing COVID-19 risks, public health messaging needs to adapt as the pandemic evolves, just as immune systems adapt to new viruses and variants.
Seven nasal vaccines for COVID-19 are currently in clinical trials around the world.

Research suggests that giving a person a vaccine through their nose can provide a better defense against future exposure to the coronavirus compared to a shot in the arm.
MS is an autoimmune disease in which elements of the immune system begin to damage the brain and spinal cord.
The causes of multiple sclerosis (MS) are complex, but recent research found Epstein Barr virus, the same virus that causes mononucleosis, is an environmental trigger for MS.
The stress of exercising while sick could potentially make our immune cells less effective.

As little as 30 minutes of exercise five times a week can benefit your immune system.
Viewing immunity as a carpet that we weave together evokes labour and artistry, and suggests we have a role in crafting something rather than simply being acted upon by a virus.
The metaphor of a collective “carpet of immunity” invites us to imagine immunity as a collaborative project, spreading out to protect those for whom the end of mandates means increased vulnerability.
Immunologists are studying how the SARS-CoV-2 virus interacts with antibodies in the immune system.

DNA and mRNA vaccines produce a different kind of immune response than traditional vaccines, allowing researchers to tackle some previously unsolvable problems in medicine.
Regret can increase stress and negatively affect one’s physical health.

Remorse and sorrow from a bad choice can haunt you for years, even decades. But there are evidence-based ways to move past regret.
If it’s been six months since your second COVID vaccine dose, it’s time to book in for your booster. Here’s why.
Many vaccine formulations are tweaked for patients of different ages.

First CDC signed off on a COVID-19 vaccine for adults, then teens. Now US children ages 5 to 11 are officially eligible for shots. Here’s the science on why each group needs to be considered separately.
Protection from infection wanes over time. So boosters will offer extra protection and hopefully reduce the spread of the virus even further.
Exercise is still one of the best ways to boost longevity.
Life-extension therapies may be coming sooner than you think.
But the immune cells that vaccination spurs do last a long time.
The estimated lifetime costs of antiretroviral therapy for someone who acquires HIV at age 35 is $358,380.

People with HIV need to take daily medication to keep the virus at bay. A study has found that a new treatment combination could boost immunity and control virus levels even after stopping medication.
Several thousand protestors opposed to the COVID-19 vaccine march through the streets of midtown Manhattan in New York on Sept. 18, 2021.

A growing body of research shows that nutrition, sleep, exercise and a host of other lifestyle choices can help optimize the immune system. But they are no substitute for life-saving vaccines.
