The gut microbiome and immune system work closely together. However, as people age, the composition and balance of microorganisms in the gut changes, with fewer beneficial bacteria.
Canada is seeing a surge in measles cases. Find out what measles is, why it’s returning to Canada, and how people can protect themselves and others.
Your immune system is often able to fend off pathogens it’s never seen before. But defending your body against all of them all at once is a tough challenge.
From breast implants to prosthetic knees, implants can trigger a foreign body response that results in your body rejecting them. Suppressing an immune cell gene could reduce this risk.
Firstly, there is no such thing as ‘too much’ immunity. Beyond the regular side-effects of a vaccine, there are no known additional risks to being re-vaccinated soon after an infection.
People with Down syndrome have an extra chromosome 21. Understanding the effects of those triplicated genes could help improve the health of those with Down syndrome and other medical conditions.
Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.
Evidence is growing there are changes to your immune system that may put you at risk of other infectious diseases.
Your blood can hold a record of past illnesses. That information can reveal how many people have had a certain infection – like 58% of Americans having had COVID-19 by the end of February 2022.
Research suggests that too-frequent immunizations may lead to a phenomenon called “immune exhaustion.”
Medications to treat COVID-19 are in no way a substitute for the vaccine. But under the right circumstances, some show great promise for helping patients.
An FDA panel has voted against recommending approval of a booster COVID-19 shot for the general population – disappointing some public health officials.
Although there is no evidence yet that it affects COVID-19 vaccines, schistosomiasis, a neglected tropical disease, has been associated with lower vaccine immunity for several vaccines.
A COVID-19 vaccine does not cause infertility – but it can protect you from the dangerous complications of contracting the virus.
COVID-19 vaccination produces a more consistent immune response than a past infection. With the delta variant, the difference in protection may be even greater.
Various companies use different ingredients and different delivery systems in their COVID-19 vaccines. Researchers are investigating whether it’s better for individuals to mix what’s available.
Most shots work best when inserted into muscle. The shoulder muscle known as the deltoid works best.
The survival of the human body is a fine balancing act between cell growth and cell death. Understanding our cells’ complex “licence to die” could give us new ways to combat disease.
Many people never experience the least bit of discomfort from the COVID-19 vaccines, but mild side effects are common. They include swelling in the affected arm, nausea and chills.
