Copyright 2018 Medical News TodayDiseases that vaccines prevent can be dangerous, or even deadly. Vaccines greatly reduce the risk of infection by working with the body’s natural defenses to safely develop immunity to disease. Vaccines help develop immunity by imitating an infection. This type of infection, however, does not cause illness, but it does cause the immune system to produce T-lymphocytes and antibodies. Once the imitation infection goes away, the body is left with a supply of “memory” T-lymphocytes, as well as B-lymphocytes that will remember how to fight that disease in the future.http://www.medicalnewstoday.comadmin@medicalnewstoday.com (MNT Admin)editors@medicalnewstoday.com (MNT Editors)en-us Tue, 24 Apr 2018 00:00:00 PDThttps://www.medicalnewstoday.com/articles/321584.phphttps://www.medicalnewstoday.com/articles/321584.phpIn a new study, researchers demonstrate that immune molecules activated by gut bacteria could negatively impact cardiac health following heart failure.Cardiovascular / Cardiology Fri, 20 Apr 2018 00:00:00 PDThttps://www.medicalnewstoday.com/articles/321561.phphttps://www.medicalnewstoday.com/articles/321561.phpHarnessing the power of immune cells, researchers create a compound that successfully treats psoriasis in mice.
